US – Oysters Vibrio parahaemolyticus Warning

Food Poisoning Bulletin 

Massachusetts health officials are warning that oysters harvested from Cape Cod Bay may be contaminated with Vibrio parahaemolyticus, a bacteria that causes about 4,500 cases of foodborne illness every year.

That area has tidal flats with shallow water that can become very warm during the day. In just the right conditions of warm temperatures and the water’s salt content, the bacteria grows very quickly  in the shellfish. Then when those oysters are eaten raw or undercooked, the bacteria can make people sick.
