The Food and Drug Administration late Friday clarified an earlier warning that all oysters, clams, mussels and scallops from Korea should be considered adulterated and removed from the market, and said that ban includes canned products.


An earlier news release from the Washington State Department of Health had said the ban excluded canned products.

The FDA says inadequate sanitation controls in Korea have exposed some shellfish there to human fecal waste, and that all fresh, frozen and processed shellfish (including canned shellfish) from Korea may be contaminated with norovirus.

Korean certified shippers of molluscan shellfish have been removed from the FDA’s Interstate Certified Shellfish Shippers List. Korean molluscan shellfish that entered the United States before May 1 and any products made with Korean molluscan shellfish are considered adulterated, the agency stated.
