Cyclospora, a microscopic parasite found in water that can spread to produce, is causing outbreaks in more than half of U.S. states, with Michigan emerging as the epicentre.
The parasite is typically found in wet and warm climates and can enter grocery stores through imported lettuce, raspberries, carrots, and other fresh produce. Once ingested, it causes severe gastrointestinal illness.
Keith Warriner, a professor of food microbiology at the University of Guelph, said the real question now is whether Canada will be next. Cyclospora outbreaks have historically been linked to imported produce, particularly from Central and South America, and contaminated produce can cross the border relatively easily.
The parasite causes symptoms including severe diarrhea, nausea, and abdominal cramping that typically appear 7 to 10 days after infection. Symptoms can persist for several weeks if untreated.
Canadian food safety authorities have not reported any cases linked to the current U.S. outbreak as of Thursday.
