FDAs evaluation of the KSSP found significant shellfish growing area deficiencies including:
- ineffective management of land-based pollution sources that can impact shellfish growing areas;
- inadequate sanitary controls to prevent the discharge of human fecal waste from fish farms and commercial fishing and aquaculture vessels operating in and adjacent to shellfish growing areas; and
- detection of norovirus in shellfish growing areas analysed by FDA during the evaluation
Because of inadequate sanitation controls, the molluscan shellfish harvested from Korean waters may have been exposed to human fecal waste and have the potential to be contaminated with norovirus.
Noroviruses are a group of viruses that cause gastroenteritis. Symptoms of illness associated with norovirus include nausea, vomiting, diarrhea, and stomach cramping. Affected individuals often experience low-grade fever, chills, headache, muscle aches and a general sense of tiredness. Most people show symptoms within 48 hours of exposure to the virus. The illness typically lasts one to two days. Norovirus is usually not life-threatening and does not generally cause long-term effects.
The removal of Korean shellfish shippers from the ICSSL is intended to stop the import of molluscan shellfish harvested from polluted waters. Korean molluscan shellfish that entered the United States prior to 1 May and any product made with Korean molluscan shellfish are considered adulterated under the Federal Food, Drug, and Cosmetic Act.
FDA recommends that food distributors, retailers, and food service operators remove from sale or service, all fresh, frozen, and processed Korean molluscan shellfish and any product subsequently made with them.
Korean molluscan shellfish represents only a small fraction of the oysters, clams, mussels, and scallops sold in the United States. FDA is currently working to determine the distribution of the product.
Distributors, retailers, and food service operators can continue to receive molluscan shellfish from any of the other shellfish shippers listed in the ICSSL.
Consumers who have recently bought molluscan shellfish and are concerned that it may have come from Korea, should contact the store from which it was purchased and ask where the shellfish were harvested. Product from Korea should not be consumed.
No US illnesses from the consumption of Korean shellfish have been reported in 2012.
