Seed Suppliers Find Biotech Contamination

More than a quarter of the nation’s seed suppliers have found corn seed contaminated with traces of a biotech variety that wasn’t approved for human consumption, the government said.

The U.S. Department of Agriculture agreed to buy the contaminated corn to ensure that it doesn’t get planted. So far, 77 of the nation’s 281 companies have asked for the purchase contracts, USDA spokesman Kevin Herglotz said Monday.

“The important thing was to get [the buyback program] up and running, to make sure we could prevent any potentially contaminated seed from being planted,” Herglotz said.

The biotech seed, named StarLink, was approved only for animal consumption because of unanswered questions about whether a special protein, called Cry9C, in the corn can cause allergic reactions in people.

Discovery of the corn in the food supply last fall forced nationwide recalls of taco shells and other products and grain shipping was disrupted as processors and handlers started testing for the grain.

Sixty-eight companies are still testing their seed, but most of the contamination would have been found by now, said Angela Dansby, a spokeswoman for the American Seed Trade Assn.

She said there have been no shortages of seed for farmers this spring.

The testing probably will continue for several years. “The seed industry and USDA will continue to bird-dog this issue or situation until there is evidence that Cry9C is no longer in corn seed,” she said.

The department has estimated, based on information supplied by the companies, that less than 1% of the 40 million bags of corn seed produced for planting this year contains some trace of StarLink.

The company that developed StarLink, Aventis CropScience of Research Triangle Park, N.C., has asked the Environmental Protection Agency to grant temporary food-use approval for the corn.

The EPA is awaiting results of an investigation into reports of possible allergic reactions to corn products.
