The StarLink corn recalls occurred in the autumn of 2000, when over 300 food products were found to contain a genetically modified corn that had not been approved for human consumption. It was the first-ever recall of a genetically modified food. The anti-GMO activist coalition Genetically Engineered Food Alert, which detected and first reported the contamination, was critical of the FDA for not doing its job. The recall of Taco Bell-branded taco shells, manufactured by Kraft Foods and sold in supermarkets, was the most publicized of the recalls. One settlement resulted in $60 million going to Taco Bell franchisees for lost sales due to the damage to the Taco Bell brand.
StarLink is a genetically modified maize, containing two modifications: a gene for resistance to glufosinate, and a variant of the bacillus thuringiensis (Bt) protein called Cry9C. Cry9C had not been used in a GM crop prior to StarLink, causing heightened regulatory scrutiny. StarLink's creator, Plant Genetic Systems, which later became Aventis CropScience during the time of the incident, had applied to the US Environmental Protection Agency (EPA) to market StarLink for use in animal feed and in the human food supply. However, because the Cry9C protein lingers in the digestive system before breaking down, the EPA had concerns about its allergenicity, and PGS did not provide sufficient data to prove that Cry9C was not allergenic. As a result, PGS split its application into separate permits for use in food and use in animal feed only. StarLink was approved by the EPA for use in animal feed only in May 1998. After the incident the company at first tried to get the application for human consumption approved, and then withdrew the product entirely from the market.
The Garst Seed Company (part of the Advanta group) was licensed by Aventis to produce and sell StarLink seed in the US.
In 2000, Genetically Engineered Food Alert was launched by seven organizations (Center for Food Safety, Friends of the Earth, Institute for Agriculture and Trade Policy, National Environmental Trust, Organic Consumers Association, Pesticide Action Network North America, and The State PIRGs) to lobby the FDA, Congress and companies to ban or stop using GMOs. One of their activities was testing food for the presence of GMOs via a lab called Genetic ID, the vice president of which was Jeffrey M. Smith.
