A Southern California company is recalling dried mushroom slices sold at Costco Wholesale stores that may have been contaminated with chemicals.
L.A. Link Corporation issued the voluntary recall Wednesday for Shiitake-Ya brand gourmet shiitake mushroom slices with a sell-by date of April 16, 2013.
The mushrooms were sold at Costco locations in California, Oregon and Washington.
The company says it discovered the mushrooms may have been contaminated with carbendazim and other chemicals.
Carbendazim is a fungicide used to control plant diseases.
The contamination was found after U.S. Food and Drug Administration regulators tested a product sample.
Shiitake mushrooms are common to Asian cuisines and have a meaty cap and woody stems.
They are often sold dried and are reconstituted for cooking.
