AUSTIN, Texas -- Whole Foods Market Inc. said Thursday that labels on a chicken salad and those on a vegan version of the salad were reversed at some of its cold food bars in the Northeast.

The mislabeled salads – a curried chicken salad and a vegan curried "chick'n" salad – were sold in 15 stores in Connecticut, Maine, Massachusetts, New Jersey and New York, Whole Foods said. In some locations, the company said the salads were sold in the cold food bars where customers can scoop food into containers, which are then weighed at the register. In other locations, it said the salads were displayed in the prepared food sections behind glass. The salads were sold on Tuesday and Wednesday.

The Food and Drug Administration noted the vegan salad contains soy, and the curried chicken salad contains egg. It said people who have an allergy or severe sensitivity to soy or eggs run the risk of serious or life-threatening allergic reaction if they eat the salads.

The company, based in Austin, Texas, said no illnesses have been reported.

Libba Letton, a spokeswoman for Whole Foods, said the mislabeled salads came from a company-owned commissary. She said the mixup was discovered by an employee in the prepared food section at one of its stores. Whole Foods is issuing a recall in line with guidelines set by the FDA and plans to post signs in stores Friday alerting customers about the mislabeled salads, she said.

Whole Foods has about 330 stores in the U.S.
