Wise Foods to test chips for StarLink corn traces WASHINGTON, July 6 (Reuters) - Wise Foods Inc. said Friday it was testing samples of its white corn tortilla chips for possible contamination with StarLink, a genetically-altered yellow corn variety that is not approved for human use. Traces of StarLink were found in a bag of white corn tortilla chips made by Wise for the supermarket chain Kash n' Karry. Kash n' Karry and its sister retailer, Food Lion, both units of Delhaize America Inc., recently recalled 11-ounce packages of white corn tortilla chips after a Florida optometrist complained to the U.S. Food and Drug Administration (FDA) about an allergic reaction after eating chips from a bag with a code date of May 23. The chips were made by Wise for the two retailers' private brands. Wise said in a statement that it hired an independent testing lab to analyze samples of its white corn tortilla chips that are currently on store shelves. The FDA is also investigating how the StarLink contamination occurred with the Wise tortilla chips. "We expect the tests to be conducted over the weekend, and will make the results of these tests available once received," David Lilly, a spokesman for Wise Foods, said in statement. "While we are confident that the findings of our independent laboratory will conclude that the StarLink protein is not present, we want the public to know that Wise will immediately remove the product from store shelves if there is any risk to consumer safety," Lilly said. StarLink, a variety of yellow corn engineered to repel pests, was approved in 1998 only for animal feed. Last autumn traces of StarLink were discovered in more than 200 kinds of chips, snack foods and flour, apparently through inadvertent commingling by farmers, grain shippers and food processors. The contamination prompted a massive recall by U.S. food makers and grocery stores. In less than two weeks, a science advisory panel to the Environmental Protection Agency (EPA) is scheduled to meet and discuss whether small amounts of StarLink can be safely permitted in human food. Aventis SA, maker of StarLink, contends the corn is safe. But environmental groups have pressed for more scientific studies to determine its impact on human health and the environment. Wise said it already required its corn supplier to audit seed records of all its farmers, to test all incoming yellow and white corn from growers, and to test all outgoing yellow corn from its distribution facility for StarLink. Until the recent incident, StarLink had never been detected in more than 10 million pounds of corn purchased from its supplier, Wise said. "As an additional precautionary measure, Wise has requested our supplier to implement testing for all outgoing white corn from the supplier to our manufacturing locations," Lilly said. Georgia-based Wise Foods distributes snack foods throughout the Eastern United States.
