The FDA said See's Candies Inc. of San Francisco initiated the voluntary recall of the 16-ounce bags of semi-sweet chocolate chips because the product might contain undeclared traces of milk, posing a health hazard for people allergic to dairy products.

The recalled product was sold in California, Arizona, Nevada, Oregon, Washington, Utah, Colorado, Idaho, Hawaii, New Mexico, Illinois, Nebraska, Iowa, Kansas, Michigan and Texas, as well as in Japan and Hong Kong. See's mail order department also sold small quantities nationwide.

The company said the recalled product was produced on a line that also is used to manufacture milk chocolates.

The product is sold in a black and white See's logo flexible bag. The recall applies to all code dates (30757, 31327, 32067, 33157, and 23397).
