The Canadian Food Inspection Agency announced that a "worrisome" parasite has been confirmed in at least one area of Prince Edward Island, and samples from several oyster farms have been sent for testing.

Daniel Williams, a technical specialist in diseases at the Canadian Food Inspection Agency, stated that the parasite known as multinucleate Sphere X - or MSX - has been confirmed in Bedeque Bay on the southern coast of the province.

However, many other locations are considered "suspected" of harboring the parasite and have been quarantined while the investigation continues to confirm its presence.

Williams mentioned that these sites include one location in Malpeque Bay on the northern shore of the province, which is a water body known for its oysters.

She explained that the parasite prefers to stay in "small pockets of areas," and if scientists can identify it quickly and prevent it from moving further, they can mitigate the damage to the industry.

The parasite affects the growth of oysters and increases mortality rates, but there are no associated health risks to humans related to MSX disease.

The agency stated that MSX has previously been found in Nova Scotia and British Columbia, but this is the first time it has been discovered in the waters of Prince Edward Island.

Tests confirmed the presence of the parasite earlier this month after the province reported significant oyster deaths in Bedeque Bay this spring.

A regional government study indicated that in 2019, Prince Edward Island accounted for 32 percent of the national economic value of oysters - about $54 million - making it one of the largest producers in Canada in terms of dollar value.
