As is so often the case for controversies before the Supreme Court, this case isn't so much about glyphosate as it is about the interface between federal and state law.
Since 1991, the EPA has held that glyphosate is not carcinogenic; it was (at the time) categorized "Group E", which means that not only is there not evidence for it being carcinogenic, but that there is material evidence that it is not. Later, IARC (in a decision that was controversial among global public health agencies) listed glyphosate as a 2A probable carcinogen, alongside red meat, potatoes, deep fryer oil, and a slew of scary chemicals that includes many other insecticides and herbicides.
States like California enacted labeling-law regimes that key in part off IARC's classification, which meant that in those states Roundup products required labeling. Monsanto/Bayer lost civil cases based on failure to label.
That's the domain-specific stuff. What the court likely cares about is the preemption doctrine. In a variety of different situations, competing state and federal statutes are by explicit or implicit preemption rules. In many cases, federal preemption is a result of bargains with industry: for instance, we got programs like Energy Star after negotiations where industry (and the states dependent on those industries) made concessions to the federal government in exchange for exemptions from state regulation, which is why there's controversy over local municipal ordinances that attempt to ban gas ranges (apropos nothing, but: combustion products of gas ranges: also IARC carcinogens).
There's a weird backstory to public opposition to glyphosate which has very little to do with glyphosate itself (as someone else on this thread pointed out, glyphosate is relatively benign and relatively inert compared other common crop and landscape treatments), but rather with the idea that glyphosate is part of the technology stack of GM crops.
For those people it's worth knowing that the civil liability Monsanto/Bayer is trying to avoid here is approximately the same as the reason Jays Potato Chips bags sometimes have "Not For Sale In California" labeling. Nobody has declared that Roundup is categorically unsafe. Some states have declared that you have to label it the same way you would a gas station or Disneyland ride.
>As is so often the case for controversies before the Supreme Court, this case isn't so much about glyphosate as it is about the interface between federal and state law.
It was mentioned on a podcast recently that in many cases, the SC is not making a decision on what should/shouldn't happen/be the policy/is correct or whatever. They are deciding which layer of government gets to decide a given question. The Executive Branch? Legislation? Constitution? Who is the controlling entity?
Now, in a practical sense, by the time it gets to the SC, making a decision on who gets to decide, is, functionally, picking what the outcome is, since the various layers of government have already made their positions clear.
But the upshot is, if one is upset with what happens with a given policy after a SC decision, in many cases (although not all), the proper target of one's ire should not be the SC; since what they are usually saying is something like "this is something that is controlled by statute. If the statute is dumb/bad/poorly written, that is not our fault nor within our control, take it up with Congress to rewrite the statue", and instead one should be upset with whoever the controlling entity is for doing a bad job (in recent years: most commonly congress, not so much for doing a bad job so much as not doing any job)
Important to note it's not Glyphosate on trial, it's Roundup. There is a huge gulf between studies and conclusions on Glyphosate, and studies and conclusions on Roundup. Glyphosate is the safest and most effective herbicide known to mankind. Roundup - which includes Glyphosate, in addition to other additives - may be unnecessarily dangerous.
Also worth noting that Monsanto could stop selling Roundup entirely, and it wouldn't really matter. Monsanto's Glyphosate patent expired, so you can get cheaper Glyphosate from many different manufacturers. Which is great, because it means we can avoid the potentially-more-dangerous Roundup, and use the simpler base chemical instead. Distancing the pesticide from the "evil corporation" might actually make people less afraid of it.
> you can get cheaper Glyphosate from many different manufacturers. Which is great, because it means we can avoid the potentially-more-dangerous Roundup, and use the simpler base chemical instead.
Unspecified Glyphosate product isn't better because it's not Roundup. If some ingredient in Roundup is dangerous, let's drop the Glyphosate conversation and look for herbicides without that other mystery chemical.
It really seems like you're looking for a reason to justify Roundup as uniquely bad, in the face of evidence, with extremely vague statements.
They literally said that Roundup is bad because of the OTHER chemicals that it contains in addition to Glyphosate which is not dangerous. Then it makes total sense to use pure Glyphosate instead of Roundup.
Of course you can claim that they are wrong about their claim. But that is another point.
> Unspecified Glyphosate product isn't better because it's not Roundup. If some ingredient in Roundup is dangerous, let's drop the Glyphosate conversation and look for herbicides without that other mystery chemical.
Like the tobacco industry before them, a Monsanto employee proposed producing a scientific paper with outside scientists: “by us doing the writing and they would just edit & sign their names so to speak” — see https://retractionwatch.com/2025/12/04/glyphosate-safety-art...
I didn’t claim there was only one study. The concern is the corporate culture introducing biases into studies. In the tobacco industry, this was a pattern.
The best-reasoned criticism of glyphosate is that it disrupts the gut biome (this is a fact). I suspect that many "gluten allergies" are actually gut biome problems from glyphosate-desiccated wheat.
Anything that reaches the gut intact disrupts (ie: manipulates, interacts with, alters, stimulates or suppresses, selects) the gut biome. I'm not pushing back on you except to say that as a mechanistic axiomatic claim of harm, it's missing most of the evidence. You could be right, but you could also be wrong; what you've said so far can't possibly be dispositive.
The mechanism of action of glyphosate inhibits several important amino acid production processes in the gut. I'm simplifying here, but not having glyphosate in the food supply would be a good thing for the gut, and the science agrees on this.
Glyphosate for field prep also doesn't really come through in food, it's much worse with the pre-harvest desiccation.
You are inferring from our crude understanding of processes in general. Evidence is more specific.
Do you have an exclusion trial comparing glyphosate vs non-glyphosate diets? This is amenable to natural experiments where one country bans it on a specific date and the neighbor does not.
> Do you have an exclusion trial comparing glyphosate vs non-glyphosate diets?
That's a rather sneaky way to invert the issue. It's fishing for random luck when you ask for more and harder to obtain evidence given existing facts pointing to possible harm. A single study that doesn't show harm doesn't refute those that do.
You have to provide hard evidence that glyphosate (or another non-essential ingredient) does not cause adverse effects, and thoroughly explain the differences with the studies that show the opposite - until you do that, any in-vitro or other studies that show harmful effects count against the use of the product and you cannot ask for more evidence, you can only accept the remedies.
In this case, the appropriate remedies can be different: banning it altogether, limiting it to specific usage (e.g. no pre-harvest spraying), labeling using LARGE PRINT and scary language or some combination of the above.
You can't even get smoked fish accepted through precautionary-principle logic like that. This is the same reasoning that puts cancer warnings on bags of potato chips.
Smoked fish is a side, wheat is a staple. Degree matters.
If 90% of the raw food at the grocery were 'processed' in the same way that a smoked fish, or a french fry was, I think we'd have very valid reasons to be displeased with many of the myriad problems that come with that.
Here's a decent one: 13% of the UK reports gluten intolerance symptoms, and only 7% of Germany does. The UK allows pre-harvest glyphosate desiccation, Germany doesn't. I would be happy to bet that the trend continues past my quick Google search.
I will never understand this bizarre obsession with gut flora. We don't know what is normal, what is a beneficial ratio or when a change happens if that is good or bad thing. No one besides the people who study these things should be much attention to gut microbiomes. We just don't have enough information to let this be an influence on decision making.
Your comment seems a little flippant honestly. I know what "disrupted" is, trust me. I developed a gluten sensitivity about 10 years ago but only figured it out 5 years ago. "Healthy" is "feels healthy" and "doesn't die young", that is pretty simple.
It sounds like you think this is about hypothetical and marginal health benefits but people have very acute and immediate physical (and cognitive) issues because of disrupted gut biome that are objectively improved by cutting out, in particular, gluten. This isn't just some weird obession.
By itself, it's simply an argument that proves too much. Anything you ingest impacts your gut flora. There can be gut microbiome hypos about glyphosate! But you have to actually have them; you can't stop at "it impacts gut flora".
AFAIK the preponderance of the evidence is that most "gluten sensitivity" is actually just a FODMAP sensitivity, which also interacts with the gut biome.
> a weird backstory to public opposition to glyphosate which has very little to do with glyphosate itself
Is it required that the public have a "good reason" for wanting something?
> glyphosate is relatively benign and relatively inert compared other common crop and landscape treatments
We used to spray DDT everywhere. This isn't exactly a resounding recommendation. Perhaps there's a case for using as little additives in farming as is possible.
> Since 1991, the EPA has held that glyphosate is not carcinogenic; it was (at the time) categorized "Group E", which means that not only is there not evidence for it being carcinogenic, but that there is material evidence that it is not.

Excuse me if I dont believe "this stuff isnt harmful".
And Arsenic was once safe.
Asbestos was the most amazing fireproof wonder material.
Thalidomide was a wonder drug with no side effects.
Tetraethyl lead was perfectly safe everywhere.
Fen-phen was a great diet drug.
Id also add "consumption of fluoride in water supply" (topical/toothpaste makes sense, consumption does not).
I mean, you can believe whatever you want to believe, and the EPA can be wrong, but "the EPA has been claiming X since 1991" is not a very powerful argument for "not X".
(There are mechanistic reasons to believe glyphosate is less harmful than other landscaping treatments; it has a fairly elegant mode of action.)
Omitted here is mention that the EPA designation is under review: “the Agency is currently updating its evaluation of the carcinogenic potential of glyphosate to better explain its findings and include the current relevant scientific information”. Their February 2020 registration review decision was withdrawn and their new interim registration has not been completed.
—https://www.epa.gov/ingredients-used-pesticide-products/glyp...
I’m not claiming you needed to mention this in your original post about the lawsuit. This fact would be relevant in the sub thread here with nekusar about what we can or cannot draw from the designation.
The logical flaw in their argument also doesn't depend on the EPA's actions! In fact, the additional color you added works against the claim, in their logic.
Part of that is that I've seen enough evidence between the FDA and EPA that regulatory capture is a thing, and more stuff that we are exposed to and consume are more poisonous than they let on.
Ive also seen that with https://en.wikipedia.org/wiki/Ractopamine which is banned in most of the world. Decent countries straight up banned it, since it doesnt degrade with slaughter or cooking. My SO is also allergic to it as well - thats evidenced by not being able to eat US/Canadian pork, but being able to eat Spanish/European pork.
Tl;dr. Regulatory capture has made most of US food not good, potentially toxic, and full of nasty shit we dont want to eat. But hey, selling toxic food makes money for someone.
I'm not arguing that the EPA is right or trustworthy. I'm saying that if you want to argue the opposite of what they claim, you need evidence beyond "the EPA disagrees with me".
I think that this will be material to me in the sense in which it resolves some questions about whether Oak Park, the ultra-blue inner-ring suburb suburb in which I live, can ban gas ranges, which I enjoy cooking on. I guess I think Bayer has the better case here.
In the message board controversy over glyphosate itself, I don't think this case has much to say. The state labeling regime was either preempted or not; that's a technicality of state and federal statutory evaluation. If the labeling regime is enforceable, it doesn't much matter whether it was about IARC classification or midichlorian counts. Strict liability is strict liability.
The substantive part of this case, whether glyphosate is an inherently dangerous or flawed product, was resolved by the trier of fact in favor of Monsanto.
A simpler way to say all of this: "the safety of glyphosate is not before this court".
> whether glyphosate is an inherently dangerous or flawed product, was resolved by the trier of fact in favor of Monsanto.
You: "Courtrooms are the appropriate final venue to determine if something is inherently dangerous, using the word inherently purposefully, as I do not misuse words, as long as the result is something I agree with."
> Oak Park, the ultra-blue inner-ring suburb suburb in which I live, can ban gas ranges, which I enjoy cooking on
I guess this is why you and I write on random social media forums instead of getting elected.
In the past several years I've proposed, help draft, and gotten passed one law (making us the first municipality in Illinois with an anti-surveillance ordinance), co-wrote our municipality's police general order on ALPRs limiting them to violent crime, and created the transparency regime that allowed us to cancel our Flock contract. I've spent the last 3 years working on eliminating single family zoning, which we are likely to accomplish in just a couple months. I've funded and run two campaigns, one of which succeeded. I'm an appointed commissioner in the muni.
I got all of this done by... posting on random forums.
haha look i'll vote for you if you run for something, but you've run a campaign, you'll agree: all the activism in the world, and the people who win student council elections have won more elections than you and i have
I'm not interested in running for office; I'm very interested in helping other people run. My theory of change doesn't involve me holding office. In fact: my theory of change is heavily dependent on posting comments! It seems to be working out for me.
It sounds like this would actually be good to decide now if the court were truly a "conservative" court - there is no legitimate reason for preemption to apply to labeling laws (even as broken as California's labeling law is), as labeling a product a certain way is not a mutually-exclusive action. But I expect the rank hypocrisy will win out, especially with the "culture war" backdrop of California delenda est.
> there is no legitimate reason for preemption to apply to labeling laws (even as broken as California's labeling law is), as labeling a product a certain way is not a mutually-exclusive action.
That's not really what preemption is about. A major point of having "interstate commerce" -- actual products crossing state lines -- at the federal level, is to prevent states from enacting trade barriers.
Suppose California disproportionately has more organic food producers and other states make higher proportions of food products grown with glyphosate. California then passes a law requiring the latter (i.e. disproportionately out-of-state) products to carry a scary warning label based on inconclusive evidence. Are they trying to enact a trade barrier? It sure looks like one. Meanwhile if the stuff is actually dangerous then it's dangerous in all 50 states, so the warning label should either be everywhere or nowhere according to the evidence, right?
Relatedly, having dozens or (at the city level) hundreds of different sets of rules is also a kind of trade barrier. Some small business in Ohio is willing to ship nationwide but every state has different rules, they might be inclined to cut off everyone who isn't in the local area since that's where they get most of their current sales, but that's bad. So then there is a legitimate interest in being able to say the rules have to be uniform if the states start trying to micromanage too much.
The better way to do this would be to only apply the interstate commerce rules to actual interstate commerce. So they could preempt California from requiring labeling on products shipped from Ohio, or require specific federal labeling on the things that are, but only California gets to decide about the things that never leave California. A lot of states would then say you have to follow the federal interstate rules even if you don't cross state lines, but it would be their decision and some might not.
> Meanwhile if the stuff is actually dangerous then it's dangerous in all 50 states, so the warning label should either be everywhere or nowhere according to the evidence, right?
Only if other states or the federal government give that much of a shit about food safety, which is not a guarantee, both in theory and in practice. They might, for instance, care more about agri-profits than California does.
> So they could preempt California from requiring labeling on products shipped from Ohio, or require specific federal labeling on the things that are, but only California gets to decide about the things that never leave California.
That's just a regulatory-arbitrage race to the bottom. You'd just have out-of-state producers that don't have to follow any of your laws out-competing local ones.
> There's a weird backstory to public opposition to glyphosate which has very little to do with glyphosate itself (as someone else on this thread pointed out, glyphosate is relatively benign and relatively inert compared other common crop and landscape treatments), but rather with the idea that glyphosate is part of the technology stack of GM crops.
I still don’t understand why people seem to care about genetically modified glyphosate tolerant soybeans and corn, they’re mostly fed to animals anyways.
Apart from the health aspect, there is the thing were these GMOs are patented and the business model is one where farmers are not allowed to keep a portion of this years yield to use to seed for next year, but essentially get roped into a subscription model for the crops they plant.
Essentially turning
> You wouldn't download a car
into
> You wouldn't plant your seed for your crop.
Which is obviously absurd.
So while GM has enabled some pretty good things, it also comes with the same sort of intellectual property baggage that plagues many different areas of society, which on the face of it make some sense, but always seem to skew towards concentrating money towards those who already live a comfortable life, squeezing from those who have less to begin with.
I don't think the case law supports this argument that farmers got roped into subscription crops. Farmers use this system because it has value, and is economically superior to the systems that preceded it (or they don't use it).
There is a problem though. If you opt out of it and just use seeds without any IP and your neighbor uses IP seeds and some of the seeds are blowing into your field from your neighbour you risk trouble.
Source that it is legal to keep the profits and the plants from a patented crop that can’t be prove you have intentionally planted it there? As far as I understand Montosanto claims it would always belong to them no matter how the seed ended up there.
Feel free to cite the case they've brought where they claim that!
They have sued farmers for innocently acquiring their seeds (through the wind or whatever) and then spraying their crops with Roundup (ie: using the whole system).
There is absolutely no case law suggesting it is illegal to harvest and keep accidentally cross contaminated seed. Seeing as farming seeds is default legal there would need to be precedent otherwise for such an act to be illegal.
> Apart from the health aspect, there is the thing were these GMOs are patented and the business model is one where farmers are not allowed to keep a portion of this years yield to use to seed for next year, but essentially get roped into a subscription model for the crops they plant.
They don't get roped into anything. They elect to do that because the crop yields are significantly better and justify the cost. Further, at least part of the reasoning for not allowing replanting is to avoid genetic deviation in future generations of crop.
It's striking how many of these "product safety" cases are decided in the court of public opinion, independent of actual scientific merit. The case of DDT was pretty interesting. More recently, we have microplastics - no one has really shown they're dangerous to humans, but there's enough hand-waving that "everyone knows" they're killing us. And aspartame, etc...
Glyphosate is probably the safest of the things people spray their lawns with. I don't think we should - the worst you get on a typical suburban lawn if you mow but don't spray are dandelions and clover - but it's probably not giving you cancer. As for food... again, there are far worse, more persistent pesticides that escape this kind of scrutiny.
Well I don't know of people claiming that microplastics are "killing us", there are dozens of papers that implicate microplastics in negative health effects from hearts to intestines, to sperm.
There are a lot of studies that find correlations, and then are studies like this one that show that the direct introduction of microplastics alters cell functions negatively:
I think at this point we should stop talking about how "there's no data" or "no studies" and "no one has shown" and graduate to "oh, maybe should figure out the extent of the damage."
Microplastic pollution is a global problem amongst a whole host of global pollution problems. We'd do well to try to figure out how bad it is, because it isn't going away. Oh, and we should probably work on fixing all of our pollution problems, especially cumulative ones like this.
People are usually spraying broadleaf herbicides on their lawn like 2,4-D to control things like dandelions and yard plantains. Glyphosate just kills everything. Personally I only use it very selectively on poison ivy.
Worth noting here that the trier of fact in this case mostly agrees with you about this stuff; the issue is that the state statutes in question created strict liability conditions for failure to comply with warning label regimes. The plaintiff brought substantive charges about Roundup to the case, and the jury rejected them.
We hand some log droughts here about 10 years ago where you were not allowed to water the lawn at all.
I would have expected a single dominate weed to take over, but instead, if I let the grass grow for 6-8 weeks in summer I get this amazing field of different knee length plants. And it alive with bee's and butterflies.
From an environmental perspective you are probably right. One of the nice things is that glyphosate, unlike most herbicides, is broken down quickly by soil bacteria.
The longer term issue is evolved weed resistance due to its over use with "Roundup Ready" crops and for end of the season dry down.
I think the fears about glyphosate resistance owes too much to antibiotic resistance, but I am not really sure it makes sense.
I suppose there's some regimen where you carefully monitor every plant sprayed with a weedkiller is monitored for survival and killed with fire if it survives, or some other extreme measure to be sure there are no survivors to develop resistance, but realistically the weeds are going to develop resistances over time.
And ... so what? The value of a weedkiller like glyphosate is using it to kill a lot of weeds in wide-scale agriculture. If the weeds develop a resistance to it, and we stop using it because it's no longer effective, we're not really in a worse position than if we never used it at all. It's not like there are some really bad weeds we need to save it to be able to combat.
That people would be on the whole less healthy had glyphosate not been on the market, because other herbicides, all of which were and are in common use, are worse.
No, mass starvation would not ensue from having to fight weeds using mechanical means. It would take more work and more fuel, but it is eminently doable if the need is there. Especially if the change would be gradual.
Making do without artificial fertilizer would be a lot harder.
Perhaps if herbicides weren't viable, more work would've gone into developing the mechanical alternatives and we'd have had solar-powered machines removing weeds from fields.
Increased work and fuel means increased costs, increased costs means increased prices, increased prices means less food available for purchase by those on the margins, less food means starvation.
No, not regardless of magnitude. But anything that have a large impact on food prices will decrease the ability of poor people to pay for it. It’s not rocket science.
I don't think that is the only alternative. If the end goal is to preserve life for humans, completely nuking the soil into a wasteland, treating it with carcinogens and then allowing a company to genetically modify seeds and copyright them is a pretty bad and short sighted strategy.
Allowing a known carcinogen to make crops "easier to harvest" has to do with profit margin not food supply. People literally use this to kill dandelions in their yards. I have known many people who have died from cancer. I have eaten dandelions, while bitter, are actually healthy. A good start would be to work with nature instead of trying to out engineer it.
If roundup is your alternative to starvation you're probably just delaying the inevitable.
> If roundup is your alternative to starvation you're probably just delaying the inevitable.
Yes. That is literally exactly what we're doing. You can't sustain the current human population without fertilizers and pesticides made from fossil fuels. Half the people on the planet would die.
If we don't want half the planet to die, we need pesticides. So do you choose a pesticide that's more harmful, or less? If you said "less", then you want glyphosate.
You both have premises that are too far apart to debate productively; what you're really debating is naturalism vs. technology, scale vs. degrowth, humanism vs. environmentalism. All worthwhile philosophical debates, but you won't get anywhere sniping at each other about them.
WHO classifies it as "Probably carcinogenic to humans". But it's important to talk about the exposure model.
Glyphosate in our food supply - almost no evidence of cancer risk. (The gut microbiome is affected though).
Direct and sustained contact to glyphosate as an agricultural worker - potentially very severe risks, particularly non-Hodgkin lymphoma. The data is strong but epidemiological.
So yeah, I think your conclusion is roughly correct. Don't bathe in it. Probably avoid using it at home or work. But otherwise, its not a serious risk to consumers.
Included in this list under the same classification (2A)[1]:
> Night shift work
> Red meat (consumption of)
> Very hot beverages at above 65 °C (drinking)
Defined as[2]:
> Group 2A: The agent is probably carcinogenic to humans
> This category is used when there is limited evidence of carcinogenicity in humans and either sufficient evidence of carcinogenicity in experimental animals or strong mechanistic evidence, showing that the agent exhibits key characteristics of human carcinogens. Limited evidence of carcinogenicity means that a positive association has been observed between exposure to the agent and cancer but that other explanations for the observations (technically termed “chance”, “bias”, or “confounding”) could not be ruled out with reasonable confidence. This category may also be used when there is inadequate evidence regarding carcinogenicity in humans but both sufficient evidence of carcinogenicity in experimental animals and strong mechanistic evidence in human cells or tissues.
A reminder that most US non-organic oats contain high levels of glyphosate residues because farmers use it as a desiccant to reduce harvest fuel consumption.
And also almost all bread in the US including organic contain 10-1000 ppb of glyphosate.
America's food supply is fucked because of rampant greed, a lack of proper regulation, and a lack of application of the precautionary principle.

That makes no sense. If you accept that Glyphosate is 100% harmless. Why on earth would you drop it?
> Why on earth would you drop [Glyphosate]?
You wouldn't. You'd drop the conversation regarding whether it was safe.
A key paper on its safety from 2000 was retracted: https://news.ycombinator.com/item?id=46161125
Like the tobacco industry before them, a Monsanto employee proposed producing a scientific paper with outside scientists: “by us doing the writing and they would just edit & sign their names so to speak” — see https://retractionwatch.com/2025/12/04/glyphosate-safety-art...

I didn’t claim there was only one study. The concern is the corporate culture introducing biases into studies. In the tobacco industry, this was a pattern.

I'm not pushing back on you except to say that as a mechanistic axiomatic claim of harm, it's missing most of the evidence. You could be right, but you could also be wrong; what you've said so far can't possibly be dispositive.
The mechanism of action of glyphosate inhibits several important amino acid production processes in the gut. I'm simplifying here, but not having glyphosate in the food supply would be a good thing for the gut, and the science agrees on this.
Glyphosate for field prep also doesn't really come through in food, it's much worse with the pre-harvest desiccation.
You are inferring from our crude understanding of processes in general. Evidence is more specific.
Do you have an exclusion trial comparing glyphosate vs non-glyphosate diets? This is amenable to natural experiments where one country bans it on a specific date and the neighbor does not.
> Do you have an exclusion trial comparing glyphosate vs non-glyphosate diets?
That's a rather sneaky way to invert the issue. It's fishing for random luck when you ask for more and harder to obtain evidence given existing facts pointing to possible harm. A single study that doesn't show harm doesn't refute those that do.
You have to provide hard evidence that glyphosate (or another non-essential ingredient) does not cause adverse effects, and thoroughly explain the differences with the studies that show the opposite - until you do that, any in-vitro or other studies that show harmful effects count against the use of the product and you cannot ask for more evidence, you can only accept the remedies.
In this case, the appropriate remedies can be different: banning it altogether, limiting it to specific usage (e.g. no pre-harvest spraying), labeling using LARGE PRINT and scary language or some combination of the above.
You can't even get smoked fish accepted through precautionary-principle logic like that. This is the same reasoning that puts cancer warnings on bags of potato chips.
Smoked fish is a side, wheat is a staple. Degree matters.
If 90% of the raw food at the grocery were 'processed' in the same way that a smoked fish, or a french fry was, I think we'd have very valid reasons to be displeased with many of the myriad problems that come with that.
Here's a decent one: 13% of the UK reports gluten intolerance symptoms, and only 7% of Germany does. The UK allows pre-harvest glyphosate desiccation, Germany doesn't. I would be happy to bet that the trend continues past my quick Google search.
I will never understand this bizarre obsession with gut flora. We don't know what is normal, what is a beneficial ratio or when a change happens if that is good or bad thing. No one besides the people who study these things should be much attention to gut microbiomes. We just don't have enough information to let this be an influence on decision making.
Your comment seems a little flippant honestly. I know what "disrupted" is, trust me. I developed a gluten sensitivity about 10 years ago but only figured it out 5 years ago. "Healthy" is "feels healthy" and "doesn't die young", that is pretty simple.
It sounds like you think this is about hypothetical and marginal health benefits but people have very acute and immediate physical (and cognitive) issues because of disrupted gut biome that are objectively improved by cutting out, in particular, gluten. This isn't just some weird obession.
We know that it's really important to neurological function, which is enough reason to be careful.
By itself, it's simply an argument that proves too much. Anything you ingest impacts your gut flora. There can be gut microbiome hypos about glyphosate! But you have to actually have them; you can't stop at "it impacts gut flora".
AFAIK the preponderance of the evidence is that most "gluten sensitivity" is actually just a FODMAP sensitivity, which also interacts with the gut biome.
Off topic, but can someone ELI5 (or at least ELI20) what the deal is with FODMAP? I keep hearing about it, but I don't understand it at all.

We used to spray DDT everywhere. This isn't exactly a resounding recommendation. Perhaps there's a case for using as little additives in farming as is possible.
> Is it required that the public have a "good reason" for wanting something?
Not required but it's a nice to have, especially if the thing they want done is to have the desired outcome.
The desired outcome is simply not using Glyphosate. I'm not seeing how "reasonability" of this idea impacts it's implementation.
If you find someone using it you severely fine them and/or put them in jail.
No, it isn't. What's your point?
> Since 1991, the EPA has held that glyphosate is not carcinogenic; it was (at the time) categorized "Group E", which means that not only is there not evidence for it being carcinogenic, but that there is material evidence that it is not. Later, IARC (in a decision that was controversial among global public health agencies) listed glyphosate as a 2A probable carcinogen, alongside red meat, potatoes, deep fryer oil, and a slew of scary chemicals that includes many other insecticides and herbicides.
Excuse me if I dont believe "this stuff isnt harmful".
And Arsenic was once safe.
Asbestos was the most amazing fireproof wonder material.
Thalidomide was a wonder drug with no side effects.
Tetraethyl lead was perfectly safe everywhere.
Fen-phen was a great diet drug.
Id also add "consumption of fluoride in water supply" (topical/toothpaste makes sense, consumption does not).
Those aren't really great examples, considering that Arsenic and Asbestos have been known to be harmful for centuries/millennia.
Thalidomide never even made it to use in the USA.
Fluoride being good for teeth was discovered by fluoride naturally being in the water already
Can't speak for the other two, but I hope you're not basing your fears on stuff like that.
I mean, you can believe whatever you want to believe, and the EPA can be wrong, but "the EPA has been claiming X since 1991" is not a very powerful argument for "not X".
(There are mechanistic reasons to believe glyphosate is less harmful than other landscaping treatments; it has a fairly elegant mode of action.)
Omitted here is mention that the EPA designation is under review: “the Agency is currently updating its evaluation of the carcinogenic potential of glyphosate to better explain its findings and include the current relevant scientific information”. Their February 2020 registration review decision was withdrawn and their new interim registration has not been completed. —https://www.epa.gov/ingredients-used-pesticide-products/glyp...
I don't really care about EPA's designation. I discussed it upthread because it's very important to the legal case.
I’m not claiming you needed to mention this in your original post about the lawsuit. This fact would be relevant in the sub thread here with nekusar about what we can or cannot draw from the designation.
The logical flaw in their argument also doesn't depend on the EPA's actions! In fact, the additional color you added works against the claim, in their logic.
Part of that is that I've seen enough evidence between the FDA and EPA that regulatory capture is a thing, and more stuff that we are exposed to and consume are more poisonous than they let on.
Ive also seen that with https://en.wikipedia.org/wiki/Ractopamine which is banned in most of the world. Decent countries straight up banned it, since it doesnt degrade with slaughter or cooking. My SO is also allergic to it as well - thats evidenced by not being able to eat US/Canadian pork, but being able to eat Spanish/European pork.
Tl;dr. Regulatory capture has made most of US food not good, potentially toxic, and full of nasty shit we dont want to eat. But hey, selling toxic food makes money for someone.
I'm not arguing that the EPA is right or trustworthy. I'm saying that if you want to argue the opposite of what they claim, you need evidence beyond "the EPA disagrees with me".
So what do you think?
I think that this will be material to me in the sense in which it resolves some questions about whether Oak Park, the ultra-blue inner-ring suburb suburb in which I live, can ban gas ranges, which I enjoy cooking on. I guess I think Bayer has the better case here.
In the message board controversy over glyphosate itself, I don't think this case has much to say. The state labeling regime was either preempted or not; that's a technicality of state and federal statutory evaluation. If the labeling regime is enforceable, it doesn't much matter whether it was about IARC classification or midichlorian counts. Strict liability is strict liability.
The substantive part of this case, whether glyphosate is an inherently dangerous or flawed product, was resolved by the trier of fact in favor of Monsanto.
A simpler way to say all of this: "the safety of glyphosate is not before this court".
> whether glyphosate is an inherently dangerous or flawed product, was resolved by the trier of fact in favor of Monsanto.
You: "Courtrooms are the appropriate final venue to determine if something is inherently dangerous, using the word inherently purposefully, as I do not misuse words, as long as the result is something I agree with."
> Oak Park, the ultra-blue inner-ring suburb suburb in which I live, can ban gas ranges, which I enjoy cooking on
I guess this is why you and I write on random social media forums instead of getting elected.
In the past several years I've proposed, help draft, and gotten passed one law (making us the first municipality in Illinois with an anti-surveillance ordinance), co-wrote our municipality's police general order on ALPRs limiting them to violent crime, and created the transparency regime that allowed us to cancel our Flock contract. I've spent the last 3 years working on eliminating single family zoning, which we are likely to accomplish in just a couple months. I've funded and run two campaigns, one of which succeeded. I'm an appointed commissioner in the muni.
I got all of this done by... posting on random forums.
haha look i'll vote for you if you run for something, but you've run a campaign, you'll agree: all the activism in the world, and the people who win student council elections have won more elections than you and i have
I'm not interested in running for office; I'm very interested in helping other people run. My theory of change doesn't involve me holding office. In fact: my theory of change is heavily dependent on posting comments! It seems to be working out for me.
It sounds like this would actually be good to decide now if the court were truly a "conservative" court - there is no legitimate reason for preemption to apply to labeling laws (even as broken as California's labeling law is), as labeling a product a certain way is not a mutually-exclusive action. But I expect the rank hypocrisy will win out, especially with the "culture war" backdrop of California delenda est.
> there is no legitimate reason for preemption to apply to labeling laws (even as broken as California's labeling law is), as labeling a product a certain way is not a mutually-exclusive action.
That's not really what preemption is about. A major point of having "interstate commerce" -- actual products crossing state lines -- at the federal level, is to prevent states from enacting trade barriers.
Suppose California disproportionately has more organic food producers and other states make higher proportions of food products grown with glyphosate. California then passes a law requiring the latter (i.e. disproportionately out-of-state) products to carry a scary warning label based on inconclusive evidence. Are they trying to enact a trade barrier? It sure looks like one. Meanwhile if the stuff is actually dangerous then it's dangerous in all 50 states, so the warning label should either be everywhere or nowhere according to the evidence, right?
Relatedly, having dozens or (at the city level) hundreds of different sets of rules is also a kind of trade barrier. Some small business in Ohio is willing to ship nationwide but every state has different rules, they might be inclined to cut off everyone who isn't in the local area since that's where they get most of their current sales, but that's bad. So then there is a legitimate interest in being able to say the rules have to be uniform if the states start trying to micromanage too much.
The better way to do this would be to only apply the interstate commerce rules to actual interstate commerce. So they could preempt California from requiring labeling on products shipped from Ohio, or require specific federal labeling on the things that are, but only California gets to decide about the things that never leave California. A lot of states would then say you have to follow the federal interstate rules even if you don't cross state lines, but it would be their decision and some might not.
> Meanwhile if the stuff is actually dangerous then it's dangerous in all 50 states, so the warning label should either be everywhere or nowhere according to the evidence, right?
Only if other states or the federal government give that much of a shit about food safety, which is not a guarantee, both in theory and in practice. They might, for instance, care more about agri-profits than California does.
> So they could preempt California from requiring labeling on products shipped from Ohio, or require specific federal labeling on the things that are, but only California gets to decide about the things that never leave California.
That's just a regulatory-arbitrage race to the bottom. You'd just have out-of-state producers that don't have to follow any of your laws out-competing local ones.
> There's a weird backstory to public opposition to glyphosate which has very little to do with glyphosate itself (as someone else on this thread pointed out, glyphosate is relatively benign and relatively inert compared other common crop and landscape treatments), but rather with the idea that glyphosate is part of the technology stack of GM crops.
I still don’t understand why people seem to care about genetically modified glyphosate tolerant soybeans and corn, they’re mostly fed to animals anyways.
Crossbreeding plants is genetic modification.
Apart from the health aspect, there is the thing were these GMOs are patented and the business model is one where farmers are not allowed to keep a portion of this years yield to use to seed for next year, but essentially get roped into a subscription model for the crops they plant.
Essentially turning
> You wouldn't download a car
into
> You wouldn't plant your seed for your crop.
Which is obviously absurd.
So while GM has enabled some pretty good things, it also comes with the same sort of intellectual property baggage that plagues many different areas of society, which on the face of it make some sense, but always seem to skew towards concentrating money towards those who already live a comfortable life, squeezing from those who have less to begin with.
I don't think the case law supports this argument that farmers got roped into subscription crops. Farmers use this system because it has value, and is economically superior to the systems that preceded it (or they don't use it).
There is a problem though. If you opt out of it and just use seeds without any IP and your neighbor uses IP seeds and some of the seeds are blowing into your field from your neighbour you risk trouble.
No in fact you do not. This is an Internet/activist myth.
Source that it is legal to keep the profits and the plants from a patented crop that can’t be prove you have intentionally planted it there? As far as I understand Montosanto claims it would always belong to them no matter how the seed ended up there.
Feel free to cite the case they've brought where they claim that!
They have sued farmers for innocently acquiring their seeds (through the wind or whatever) and then spraying their crops with Roundup (ie: using the whole system).
There is absolutely no case law suggesting it is illegal to harvest and keep accidentally cross contaminated seed. Seeing as farming seeds is default legal there would need to be precedent otherwise for such an act to be illegal.
> Apart from the health aspect, there is the thing were these GMOs are patented and the business model is one where farmers are not allowed to keep a portion of this years yield to use to seed for next year, but essentially get roped into a subscription model for the crops they plant.
They don't get roped into anything. They elect to do that because the crop yields are significantly better and justify the cost. Further, at least part of the reasoning for not allowing replanting is to avoid genetic deviation in future generations of crop.
There are IP protections for non-GMO seeds as well.
It's striking how many of these "product safety" cases are decided in the court of public opinion, independent of actual scientific merit. The case of DDT was pretty interesting. More recently, we have microplastics - no one has really shown they're dangerous to humans, but there's enough hand-waving that "everyone knows" they're killing us. And aspartame, etc...
Glyphosate is probably the safest of the things people spray their lawns with. I don't think we should - the worst you get on a typical suburban lawn if you mow but don't spray are dandelions and clover - but it's probably not giving you cancer. As for food... again, there are far worse, more persistent pesticides that escape this kind of scrutiny.
Well I don't know of people claiming that microplastics are "killing us", there are dozens of papers that implicate microplastics in negative health effects from hearts to intestines, to sperm.
https://www.nejm.org/doi/full/10.1056/NEJMoa2309822
https://pubs.acs.org/doi/10.1021/acs.est.3c09524
https://pubs.acs.org/doi/10.1021/acs.est.1c03924
https://www.thelancet.com/journals/ebiom/article/PIIS2352-39...
There are a lot of studies that find correlations, and then are studies like this one that show that the direct introduction of microplastics alters cell functions negatively:
https://pmc.ncbi.nlm.nih.gov/articles/PMC12692081/
I think at this point we should stop talking about how "there's no data" or "no studies" and "no one has shown" and graduate to "oh, maybe should figure out the extent of the damage."
Microplastic pollution is a global problem amongst a whole host of global pollution problems. We'd do well to try to figure out how bad it is, because it isn't going away. Oh, and we should probably work on fixing all of our pollution problems, especially cumulative ones like this.
https://www.theguardian.com/environment/2026/jan/13/micropla...
(This is a summary of a Nature Matters Arising article).
People are usually spraying broadleaf herbicides on their lawn like 2,4-D to control things like dandelions and yard plantains. Glyphosate just kills everything. Personally I only use it very selectively on poison ivy.
Worth noting here that the trier of fact in this case mostly agrees with you about this stuff; the issue is that the state statutes in question created strict liability conditions for failure to comply with warning label regimes. The plaintiff brought substantive charges about Roundup to the case, and the jury rejected them.
> the worst you get on a typical suburban lawn if you mow but don't spray are dandelions and clover
I also get a lot of morning glory AKA bindweed that kills my grass. But spraying doesn't really help with that anyway, so :shrug:.
Bindweed is evil incarnate in plant form. Wouldn't wish that on anybody.
We hand some log droughts here about 10 years ago where you were not allowed to water the lawn at all.
I would have expected a single dominate weed to take over, but instead, if I let the grass grow for 6-8 weeks in summer I get this amazing field of different knee length plants. And it alive with bee's and butterflies.
I much prefer it to lawn.
Still probably the safest herbicide, mainly because the competition (organophosphates, etc.) is so much worse.
From an environmental perspective you are probably right. One of the nice things is that glyphosate, unlike most herbicides, is broken down quickly by soil bacteria.
The longer term issue is evolved weed resistance due to its over use with "Roundup Ready" crops and for end of the season dry down.
I think the fears about glyphosate resistance owes too much to antibiotic resistance, but I am not really sure it makes sense.
I suppose there's some regimen where you carefully monitor every plant sprayed with a weedkiller is monitored for survival and killed with fire if it survives, or some other extreme measure to be sure there are no survivors to develop resistance, but realistically the weeds are going to develop resistances over time.
And ... so what? The value of a weedkiller like glyphosate is using it to kill a lot of weeds in wide-scale agriculture. If the weeds develop a resistance to it, and we stop using it because it's no longer effective, we're not really in a worse position than if we never used it at all. It's not like there are some really bad weeds we need to save it to be able to combat.
What point are you trying to illuminate with this comment?
A 22 caliber is safer than a 40 caliber. But, I still wouldn’t a hole made in me from either.
That people would be on the whole less healthy had glyphosate not been on the market, because other herbicides, all of which were and are in common use, are worse.
It's not a complicated argument.
The alternative is mass starvation.
No, mass starvation would not ensue from having to fight weeds using mechanical means. It would take more work and more fuel, but it is eminently doable if the need is there. Especially if the change would be gradual.
Making do without artificial fertilizer would be a lot harder.
Increased fuel means a lot more CO2. That is a very significant factor you cannot ignore.
More CO2 compared to what tractors use today, yes. But that is not a lot compared to the rest of the human civilization spend on transportation.
So no, it is not a very significant factor.
Perhaps if herbicides weren't viable, more work would've gone into developing the mechanical alternatives and we'd have had solar-powered machines removing weeds from fields.
Increased work and fuel means increased costs, increased costs means increased prices, increased prices means less food available for purchase by those on the margins, less food means starvation.
So anything that effects food prices, regardless of magnitude, causes mass starvation?
No, not regardless of magnitude. But anything that have a large impact on food prices will decrease the ability of poor people to pay for it. It’s not rocket science.
Then it's a discussion about magnitude and jumping to starvation is unfounded.
Anything that causes food prices to rise a lot causes starvation yea, when prices go up people consume less.
I don't think that is the only alternative. If the end goal is to preserve life for humans, completely nuking the soil into a wasteland, treating it with carcinogens and then allowing a company to genetically modify seeds and copyright them is a pretty bad and short sighted strategy.
Allowing a known carcinogen to make crops "easier to harvest" has to do with profit margin not food supply. People literally use this to kill dandelions in their yards. I have known many people who have died from cancer. I have eaten dandelions, while bitter, are actually healthy. A good start would be to work with nature instead of trying to out engineer it.
If roundup is your alternative to starvation you're probably just delaying the inevitable.
> If roundup is your alternative to starvation you're probably just delaying the inevitable.
Yes. That is literally exactly what we're doing. You can't sustain the current human population without fertilizers and pesticides made from fossil fuels. Half the people on the planet would die.
If we don't want half the planet to die, we need pesticides. So do you choose a pesticide that's more harmful, or less? If you said "less", then you want glyphosate.
I think you meant to write herbicide rather than pesticide.
You both have premises that are too far apart to debate productively; what you're really debating is naturalism vs. technology, scale vs. degrowth, humanism vs. environmentalism. All worthwhile philosophical debates, but you won't get anywhere sniping at each other about them.
The evidence on glyphosphate causing cancer isn’t particularly strong.
I wouldn’t bathe in the stuff, but the data strongly indicates it’s one of the more benign compounds used in agriculture and landscaping.
WHO classifies it as "Probably carcinogenic to humans". But it's important to talk about the exposure model.
Glyphosate in our food supply - almost no evidence of cancer risk. (The gut microbiome is affected though).
Direct and sustained contact to glyphosate as an agricultural worker - potentially very severe risks, particularly non-Hodgkin lymphoma. The data is strong but epidemiological.
So yeah, I think your conclusion is roughly correct. Don't bathe in it. Probably avoid using it at home or work. But otherwise, its not a serious risk to consumers.

Roundup has saved far more lives than it may have cut short, if any.
Only a matter of time before japanese knotwood takes over north america. Glyphosate seems to be the only thing that stops this aggressive weed
Goats > glyphosate
If you found a way to train them to only eat the weeds I think you’d be onto something
They definitely taste better.
A reminder that most US non-organic oats contain high levels of glyphosate residues because farmers use it as a desiccant to reduce harvest fuel consumption.
And also almost all bread in the US including organic contain 10-1000 ppb of glyphosate.
America's food supply is fucked because of rampant greed, a lack of proper regulation, and a lack of application of the precautionary principle.
