The U.S. Centers for Disease Control (CDC) said that allergic reactions in consumers were not caused by traces of Aventis’ StarLink corn variety in food products.

The CDC’s Web site says “the investigation did not find any evidence that hypersensitivity to the Cry9c protein was responsible for the self-reported allergic responses last fall.”

StarLink, a corn variety engineered to repel destructive pests, was approved by the Environmental Protection Agency for use only as animal feed in 1998. EPA scientists have expressed concern that the variety may trigger reactions such as rashes, breathing problems or diarrhea in humans.

More than 300 snack foods, taco shells and other products containing corn flour were recalled in October due in part to those concerns, and after it was discovered that some StarLink corn had inadvertently entered the corn supply used in food manufacturing.
