Beginning July 1, 2010, a European Commission Regulation allowing import of live and fresh molluscan shellfish and certain marine invertebrates from the U.S. will expire. This is expected to halt the import of these products into the European Union (EU) at that time.
The Regulation includes live and fresh bivalve mollusks, echinoderms, tunicates, and marine gastropods from all U.S. states. Shellfish from the five states bordering the Gulf of Mexico are already not allowed into the EU for other reasons. Wild scallop meats, fresh or frozen, will be allowed entry; whole scallops or scallop adductor muscles with the roe attached will not be allowed.
The U.S. Food and Drug Administration (FDA) and the European Union have been in discussion about the reciprocal equivalence between the nations for live mollusks but for now differences have not been resolved.
