Three cocoa products packaged for Christmas sale are being recalled because they may contain the industrial chemical melamine.

Wisconsin authorities say the products -- G&J -- are sold nationwide at Shopko and Big Lots stores.

They include G&J Hot Cocoa Stuffer, G&J His and Hers Hot Cocoa Set and G&J Cocoa in French vanilla and double chocolate flavors. No illnesses from consuming the products have been reported so far, but a few samples tested positive for melamine.

Consumers should return the products to the store where they bought them for a refund.
