The dips were distributed nationwide primarily through Costco and Trader Joe's grocery stores, the California Department of Health Services said Friday. They are: Senor Felix's 5-Layer Fiesta Dip, Delicioso 5-Layer Fiesta Dip and Trader Joe's 5-Layer Fiesta Dip.

The dips contain layers of black beans, salsa, guacamole, nacho cheese and sour cream. The recall applies to products prepared without preservatives with an expiration date of Feb. 9 or earlier and products prepared with preservatives with an expiration date of March 4 or earlier.
