Mexico Argues Glyphosate In GM Corn Is Unsafe For Human Consumption (reuters.com) 106

Posted by BeauHD from the safety-first dept.
Mexico is waiting for the United States to provide evidence that shows imported genetically modified corn is safe for human consumption. "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," reports Reuters. From the report: [Deputy Agriculture Secretary Victor Suarez] said the onus is now on the United States to show GM corn is not harming Mexico's population, which consumes a higher amount of corn than many countries through daily diet staples like nixtamalized dough and tortilla. The United States "argues that the decisions in Mexico are not based on science and that their decisions are," Suarez told Reuters in an interview. "But we still haven't seen the science of the United States or the companies. We are looking forward to that study with great pleasure."

A spokesman for the U.S. Department of Agriculture said Mexico's approach to biotechnology runs counter to "decades' worth of evidence demonstrating its safety." A senior official for the U.S. Trade Representative said, "Scientific authorities, including in Mexico, have consistently found biotech products like corn to be safe over a period of decades." [...] Mexico's written response cited studies it said showed links between GM corn consumption and glyphosate exposure to liver inflammation in people and impacts to immune response in animals, saying it considers the risk to human health "extremely serious."

The United States in August requested a dispute settlement panel under the USMCA over Mexico's decree to ban GM corn for human consumption, specifically in the use of making flour for tortillas. The decree allows the use of GM yellow corn in animal feed, which accounts for the majority of Mexico's nearly $5.9 billion worth of U.S. corn imports annually. Washington argues Mexico's decree banning imports of GM corn used for tortillas is not based on science and violates its commitments under the USMCA, which has been in place since 2020. "There is no impact on trade," Suarez said of Mexico's decree. "The value and volume of exports of GM corn to Mexico has increased."

Mexico's decree also calls for the gradual substitution of GM corn, a point of contention highlighted by U.S. officials. In its written response, Mexico argued that no specific time frame has been established and therefore it has had no trade impact. "It is a strategic goal, like the United States would like to have energy sovereignty and energy self-sufficiency," Suarez said. The United States is expected to issue a rebuttal to Mexico's response.

        Glyphosate is an issue for farmer workers exposed during spraying.

        Using glyphosate as a desiccant is also a concern and is banned in the EU.

        But glyphosate is sprayed on corn months before it is harvested. It is not a persistent chemical and the amount present in harvested grain is infintesimal.

        This is protectionism rather than real concern about health effects.

    The article mashes two issues together, that really need to be considered separately.

    First, glyphosate. From a paper reviewing know results: "a scientific community consensus does not exist at the present time, and glyphosate’s safety and health consequences are controversial." Certainly, it is not dramatically dangerous, but the discovery that it persists much longer in soil than expected, and the sheer mass of exposure that we have, means that small dangers may accumulate. This is not an open-and-shut issue.

    Second, GM. GM is not, in and of itself, a problem. The question is: what genetic changes have been made? Each individual change to a plant's genetics can have its own consequences. Which means that each individual genetic change needs to be individually reviewed. Just as an example: some kinds of pest resistance involve introducing pesticides into the product. Externally applied pesticides can be washed off. If they are an integral part of the grain, well...

      This is the corn that is highly resistant to glyphosate, so farmers can spray it over their cropland liberally and kill only the competing weeds.

      Normally, you do not spray your crop with glyphosate; so roundup-ready GM crops increase the amount of it dramatically. How big a problem this is, is another question completely.

          With a non-gm crop you cannot spray on the crop itself or it dies, so once the weed reaches your crops you are fucked. To solve this you create safe zones around the crops and those zones you have to spray vigilantly to keep them weed free and to prevent any weed to spread from there to your crops.

          With a gm crop however there are no dangers of letting the weed reach your crops, so instead you simply spray on the entire crop field on a much more lenient schedule to just keep the weed in check

          For corn, once it gets established, I wouldn't think weeds matter that much. Corn is taller than I am, assuming it gets enough water, so it isn't as though weeds are competing for light meaningfully, and the weeds may be tilled under at the end of the year anyway along with the corn stalks, so there's potentially little to no long-term soil nutrient depletion, either, though there might be if you're doing no-till.
