French supermarket Auchan is recalling a line of fish n' chips style "cod" fillets because of a labeling mix up.

The product, which actually contains flounder, is processed by Brittany, France-based processor Cité Marine.

A warning to consumers with an allergy to eggs was missing from packaging. Eggs are used to make batter and similar coatings.

The product sold under Auchan's Le Poissonnier brand relates to batch number 9282528 with a validity date of Oct 28.
