Joint Statement – Detection of MSX in Bedeque Bay, Prince Edward Island

The Canadian Food Inspection Agency (CFIA) has confirmed the presence of multinuclear sphere X (MSX) caused by Haplosporidium nelsoni in wild oyster samples collected in Bedeque Bay, Prince Edward Island (PEI). While MSX prevents oysters from thriving, such as decreased rates of growth and increased oyster mortality, this disease poses no risk to human health, nor does it pose a risk to food safety.
