Quebec's recent surge in cyclosporiasis cases has sparked concern, with 223 cases reported since the beginning of the year, compared to an average of 70 cases from 2022 to 2025. This increase is particularly notable given the disease's travel-related origins, primarily attributed to Mexico. The intestinal illness, characterized by severe diarrhea, is caused by the microscopic parasite cyclospora, which is typically contracted through contaminated food and water. The Quebec Health Ministry has confirmed that the majority of cases are linked to travel exposure, especially to Mexico, and has urged residents to prioritize local and Canadian produce to mitigate the risk of infection. The ministry is actively investigating the outbreak, focusing on imported fresh produce, and has issued a questionnaire to patients with local cases not linked to travel. The Canadian Food Inspection Agency is also monitoring the situation, conducting routine testing of imported fresh produce, and collaborating with federal and provincial health partners. While the investigation is ongoing, the agency reassures the public that there is no evidence of contaminated products distributed in Canada. The Public Health Agency of Canada supports this, noting that reported cases in Canada are linked to travel or imported produce. The rise in cases has prompted discussions about improved technology and testing capabilities, with many Quebec labs upgrading their technology for more accurate detection. However, experts caution that the increase in testing and awareness may also contribute to the perceived surge. The situation highlights the importance of vigilance and collaboration between healthcare professionals, public health authorities, and the public to manage and prevent the spread of cyclosporiasis.
