HARRISBURG, Pa. (CBS) – Pennsylvania authorities are advising people not to eat fresh or frozen shellfish from Korea.

The FDA has not issued an official recall, but state Department of Agriculture spokeswoman Samantha Krepps advises Pennsylvanians to discard or return fresh or frozen shellfish products from Korea.

“What we’ve heard so far from the FDA is that the shellfish is coming from polluted waters, and may cause illness. So as a precautionary measure, we want to let consumers in Pennsylvania know that you shouldn’t eat the Korean shellfish, which includes oyster, clams, mussels and scallops.”

But Krepps says that does not include canned shellfish. The state is not aware of any illnesses but anyone has become sick after consuming Korean shellfish is asked to call 1-877-PA-HEALTH.
