Grupo Maseca, Mexico’s top producer of corn flour, says it will phase out its use of genetically modified corn. Mexico purchased $500 million of US corn in 1998. [Food & Drink Weekly, 9/13/1999; Canadian Business, 10/8/1999]

Dr. Ignacio Chapela, a microbial ecologist, and his assistant, David Quist, a graduate student at UC Berkeley, discover the presence of genetically modified (GM) genes in native Mexican maize growing in the remote hills of Oaxaca, Mexico. The contaminant genes contain DNA sequences from the cauliflower mosaic virus, which is often used as a promoter to “switch on” insecticidal or herbicidal properties in GM plants. Contamination is also found in samples from a government food store that purchases animal feed from the US. The Oaxaca region is considered to be the birthplace of maize and the world’s center of diversity for corn, “exactly the kind of repository of genetic variation that environmentalists and many scientists had hoped to protect from contamination,” the New York Times reports. Scientists worry that the genes could spread through the region’s corn population reducing its genetic diversity. Critics of genetically modified crops have long argued that the technology cannot be contained. According to Dr. Norman C. Ellstrand, evolutionary biologist at University of California at Riverside, the discovery “shows in today’s modern world how rapidly genetic material can move from one place to another.” The findings are not good news for the biotech industry which is currently lobbying Brazil, the European Union, and Mexico to lift their embargoes on genetically modified crops. [New York Times, 10/2/2001; Manchester Guardian Weekly, 12/12/2001; BBC, 3/13/2002] It is later learned that the contamination resulted from Oaxacan peasants planting kernels they purchased from a local feed store. Though there’s a moratorium on the growing of GM crops, there’s no such ban on animal feed containing GM seed. [Cox News, 10/2/2001]

Mexico’s Ministry of the Environment and Natural Resources announces that it has found genetically modified (GM) corn growing in 15 different localities. It began investigating potential GM contamination after two Berkeley scientists found maize growing in Oaxaca (see October 2000) that was contaminated with genetically engineered DNA sequences from the cauliflower mosaic virus. [New York Times, 10/2/2001] Mexico does not release its study until January 2002 (see January 2002).

Jorge Soberon, the executive secretary of Mexico’s biodiversity commission, announces that government scientists have confirmed that genetically modified (GM) corn is growing in Mexico. The finding supports what two US scientists reported several months earlier (see Late November 2001) in a highly controversial paper published in the journal Science. Calling it the “world’s worst case of contamination by GM material,” he says 95 percent of the sites sampled in Oaxaca and Puebla were found to have GM maize. Samples taken from these sites indicated a contamination level as high as 35 percent. [Daily Telegraph, 4/19/2002; Mother Jones, 7/9/2002]

The US, Mexico, and Canada enter into a trilateral agreement that allows food and grain shipments to have GM contamination levels as high as 5 percent. Shipments containing less than the five percent level will only have to bear a label indicating that the grain may contain genetically modified organisms. Additionally, accidental contamination of corn shipments into Mexico will not trigger any labeling requirements. Only the distributor will have to be informed of the contamination. The Mexican government enters into the agreement without the Mexican Senate’s approval. [Associated Press, 2/26/2004] Critics of the deal say the US is attempting to protect agricultural biotech companies and US agriculture. A large percentage of the country’s crop is genetically modified and as a result US farmers and biotechs are having a tough time finding markets abroad. Raising the acceptable contamination limits in other countries will help increase US grain exports. Critics also say that the deal could have a dramatically adverse effect on the genetic diversity of Mexico’s maize. It could result in the planting of more genetically modified corn since small farmers have been known to occasionally plant feed as seed. A few years before, maize growing in Oaxaca and Puebla was discovered to contain genetically modified genes (see October 2000; April 18, 2002). It is believed that the contamination was caused in part by farmers who had planted feed from local stores selling grain imported from the US. The ETC Group, a Canadian-based organization that is opposed to genetically modified crops, warns that if Mexico permits the import of grain with such high levels of contamination, the country’s “maize crop would be riddled with foreign DNA from the Rio Grande to Guatemala in less than a decade.” [ETC Group, 2/26/2004] Greenpeace believes that US efforts to convince countries to lower the accepted levels of contamination are aimed at undermining the Cartagena Protocol on Biosafety (see January 24-29, 2000), which has been set up to regulate transboundary shipments of genetically modified organisms.
