The Quebec Health Ministry has issued a public health advisory urging residents to favor locally grown fruits and vegetables as the province records a sharp increase in cyclosporiasis cases. Between May 1 and July 21, 2026, officials confirmed 140 infections, a rise from the 40 cases reported during the same period in 2025.
Cyclosporiasis is a parasitic illness that typically spreads through the consumption of contaminated fresh produce. The infection often produces gastrointestinal symptoms such as watery diarrhea, abdominal cramps, nausea, and fever, and can lead to dehydration that may require medical treatment. Symptoms usually appear within a week of exposure and may persist for several weeks.
Health authorities note that the parasite is frequently linked to produce that has been washed with contaminated water or handled under unsanitary conditions. Because the source of the recent increase has not been pinpointed, the ministry emphasizes preventive measures that reduce overall risk. The advisory advises consumers to purchase produce cultivated within Quebec, where shorter supply chains and stricter traceability can make it easier to verify safety standards.
In addition to buying local, the ministry recommends that all fresh fruits and vegetables be washed thoroughly under running water before eating, and that those that can be cooked be heated to temperatures that destroy the parasite. The guidance applies to all varieties of produce, including leafy greens, berries, and melons, which have historically been associated with cyclosporiasis outbreaks.
The health ministry continues to monitor the situation through its notifiable disease reporting system, providing weekly updates on case numbers and any identified sources. Officials are working with growers, distributors, and retailers to reinforce safety protocols and to ensure that any contaminated batches are quickly removed from the market. Residents are asked to remain vigilant and to report any illness that aligns with cyclosporiasis symptoms to their health care provider.
