Pacific waters oysters are being recalled across that nation.
The Canadian Food Inspection Agency believes raw oysters harvested before August 18th may be contaminated with vibrio parahaemolyticus.
This is a bacteria commonly found in high volumes of coastal waters when temperatures rise.
The bacteria are often destroyed when shellfish are cooked properly.
Symptoms include diarrhea, stomach cramps, nausea, vomiting, fever, and headaches.
No injuries have been reported as of Wednesday.
The Agency recommends anyone with BC coastal waters oysters should return them or throw them away.
