Prince Edward Island Detects Echinococcus Multilocularis

Residents of Prince Edward Island, Canada, were recently informed that a small tapeworm, primarily found in foxes and coyotes, known as Echinococcus multilocularis, has been detected at high levels.

Research conducted by the Atlantic Veterinary College shows that between 20 to 30% of red foxes and coyotes on the Island carry the parasite. Although rare, Echinococcus multilocularis can cause a disease in humans called alveolar echinococcosis.

The parasite is mainly spread through the feces of infected animals such as foxes, coyotes, and occasionally dogs.

Humans can become infected if they accidentally ingest microscopic eggs in contaminated food, water, soil, or through close contact with animals that have been exposed to the parasite.

"While it's essential to be aware, this is not a cause for alarm. Even in parts of Canada and Europe where this parasite has been present for some time, human infections are rare. Preventive steps, such as washing hands, washing or cooking wild-picked foods, and consulting your veterinarian about deworming your pets, are highly effective, according to a statement by Dr. Marguerite Cameron, an epidemiologist with the Chief Public Health Office.

As of September 15, 2025, Canadian public health officials emphasize that the risk to human health remains extremely low, even in regions where the parasite is well-established. Additional details were disclosed on October 3, 2025.
