You can find the document submitted by Mexico here: https://www.iatp.org/sites/default/files/2024-03/MexUSMCAInitialEng.pdf

On the point of transgenic varieties having a negative impact on local strain diversity, I think the concerns are valid. The introduction of high-yielding GMOs can lead to displacement of local varieties and ultimately decrease diversity.

I skimmed through the document to see if they make some good points about the health impact of GMOs. From what I can gather, the arguments are:

• Glyphosate herbicides are commonly used when farming GMO corn. There is no global consensus on the potential long-term health effects associated with exposure to glyphosates and formulations that contain it.

• Techniques to modify the genome are not perfect. Often, viruses are used, and some viral proteins could be inserted into the genome. Other things could go wrong. Ultimately, you may have an unexpected phenotype that turns out to make the plant toxic.

• They argue that the GMO corn has a worse nutritional profile than native varieties. This worse nutritional profile ultimately has a negative health impact.

Personally... Maybe the glyphosate claim I can get somewhat behind but the other two health claims I don't find compelling. The risks over-stated, and their use of citations is not great.

I have an example of their use of citations that made me chuckle... They write:

Mexican corn, mainly native corn, has a better quality in nutritional terms, including compounds that prevent diseases and promote human health.^75^

And the citation reads:

^75^ In Mexico there are scientific compilations and files that bring together the aforementioned literature.

Ah, well, thank you for that 😅

In a written submission to a panel of the United States-Mexico-Canada Agreement, Mexico, the top buyer of U.S. corn, argued that science proves GM corn and the herbicide glyphosate are harmful to human health and its native varieties, and that its decree to ban GM corn for human consumption is within its right.

TBF, we're not picking on Mexico, we give it to our own people too. I like that they're making them prove it's safe as opposed to proving it's harmful. That's the way to go about it.

anytime I see anything about GMO, and anything about Monsanto, that doesn't explicitly mention the health impacts of glyphosate and or other chemical herb and pesticides, I die a little inside.

and yeah there's a passing mention, but it's linked directly to the GM crops, as if they're hand in hand. I dunno i've spent too long around hippies who have no idea what they're talking about.

Do... do they not know that corn was selectively bred from what amounts to a wheat like grass? Modern corn is NOTHING like its wild ancestor (which still grows there) granted thats a different method of altering what genes are or are not there but its still a form of modification by humans. What we used to do is just a very crude and haphazard way of doing it in a way that we have no idea what actually happened whereas with modern GMO, you are making very specific changes.
