Canada’s food inspection agency has detected the first confirmed cases of the aquatic animal disease dermo in oyster samples collected in Quebec and Prince Edward Island.

Oyster samples taken in Egmont Bay, P.E.I., were found to have dermo, also known as perkinsosis, says a July 4 statement from the Canadian Food Inspection Agency (CFIA). This is the first confirmed case in the province.
