Dermo Detected in Prince Edward Island Oysters
The Canadian Food Inspection Agency (CFIA) has confirmed the presence of the aquatic animal disease Dermo (also known as Perkinsosis) in oyster samples collected in Egmont Bay, Prince Edward Island (PEI). Dermo does not pose a risk to human health or food safety, but it can cause increased oyster mortality and decreased growth rates. This is the first confirmed case of Dermo in PEI.
To limit the spread of the disease, the CFIA, Fisheries and Oceans Canada (DFO) and the Province of PEI are working together with partners to monitor the situation and take necessary action. These actions are part of the Government of Canada’s One Health approach to prepare for, detect, and manage animal diseases.
