US EditionDermo Disease Confirmed in Quebec, P.E.I. Oysters
- The Canadian Food Inspection Agency confirmed the first case of dermo disease in oysters from Egmont Bay, Prince Edward Island, in a news release issued on July 4, 2025.
- This confirmation follows the initial detection eight months earlier in New Brunswick oysters near the Confederation Bridge, with the CFIA establishing primary control zones to limit spread.
- Dermo, caused by the parasite Perkinsus marinus, affects only oysters and is transmitted mostly among one- to three-year-old oysters, causing mortality rates typically between 50 and 75 percent.
- The CFIA indicated that if a product within a PCZ is considered potentially risky, its transportation will be regulated, requiring a permit from the agency for any movement inside, through, or outside the zone to help prevent disease transmission.
- The confirmation of dermo in P.E.I. and Quebec signals increased risk to the oyster industry but does not pose food safety concerns for humans consuming affected oysters.
