Little Mermaid Smoke House is recalling its Smoked Herring and Pickled Herring because the viscera of the fish were not removed and the products now pose a risk of contamination by Clostridium botulinum, according to the U.S. Food and Drug Administration.

Botulism bacteria can cause life-threatening illness and consumers are warned not to eat the products even if they don’t look or smell spoiled.

The recalled products are manufactured by Little Mermaid Smoke House and were distributed in California. The products are sold as whole fish, packaged in vacuum-sealed packaging, and labeled “Little Mermaid Smoke House.” There are no codes listed on the products. The recall includes products sold before April 3.
