A California company is recalling various guacamole dips because the avocados used in them may be contaminated with Listeria monocytogenes.

Fresh Food Concepts, Inc. of Buena Park was notified by the U.S. Food and Drug Administration (FDA) that routine sampling of its Layer Dip products revealed that the imported avocado pulp contained the bacteria, the FDA said in a news alert late Friday.

The company said it has stopped using avocado from the supplier. 

The dips were distributed nationwide in the U.S. and in Canada through retail supermarkets and club stores.
