StarLink is a brand of transgenic 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 became Aventis CropScience during the time of the incident, had applied to the United States Environmental Protection Agency (EPA) to market StarLink for use in both animal feed and human foods. The Garst Seed Company (part of the Advanta group) was licensed by Aventis to produce and sell StarLink seed in the US.

However, because the Cry9C protein lingers in animal digestive systems 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 foods intended for human consumption and for use in animal feed only. StarLink was approved by the EPA for use in animal feed in May 1998. Following the recalls, PGS at first tried to get the application for human consumption approved, and then withdrew the product entirely from the market.
