Maryland health officials issued a warning to consumers Thursday, advising them not to eat any fresh or frozen molluscan shellfish that come from South Korea because they are considered potentially unsafe for consumption.
Shellfish grown and produced in Maryland are not affected.
The affected Korean shellfish includes fresh or frozen oysters, clams, mussels, and whole and roe-on scallops, either shucked or in the shell, whole or in part. This includes frozen breaded shellfish products from South Korea.
Health officials said there are no recent cases of illness in Maryland known to be related to Korean shellfish.
Maryland health officials said the warning follows action by the federal Food and Drug Administration, which removed certified dealers in Korean shellfish from an approved list of shippers on May 1, because of potentially unsafe product. Maryland officials have contacted the state’s major distributor, and affected Korean shellfish products have been pulled off grocery shelves, according to Alan Brench, chief of food emergency response and planning at the Maryland Department of Health and Mental Hygiene.
