oysterVibrio parahaemolyticus is a naturally occurring bacterium in sea water. Its numbers increase when water temperature rises during the summer months. The bacteria may grow in molluscan shellfish such as clams, oysters and mussels when seawater temperatures are warmer and then, when those shellfish are eaten raw or undercooked,  a foodborne illness may occur. The largest outbreak of V. parahaemolyticus in BC history occurred in 2015, when 62 persons became ill.
