Cases of cyclosporiasis are surging across the United States, with Michigan alone reporting nearly 1,000 confirmed cases as of July 8. This is a stark contrast to the national average, which recorded just 145 cases from May 1 to June 16, showcasing the rapid escalation of this local outbreak.
The culprit behind this distressing intestinal illness is the Cyclospora parasite, responsible for causing symptoms like watery diarrhea, stomach cramps, bloating, and increased gas. As these cases continue to rise, especially in Southeast Michigan, health officials are left wondering about the source of the outbreak.
The Michigan Department of Health and Human Services (MDHHS) has created a dedicated webpage to monitor the situation, showing an alarming count of 992 cases. Interestingly, none of the first 145 individuals affected reported any international travel, raising questions about domestic sources of infection.
Traditionally, Cyclospora is more common in tropical and subtropical regions, and the U.S. has seen foodborne outbreaks attributed to imported produce nearly every year. Past outbreaks have been linked to items such as basil, cilantro, and raspberries. Traceback investigations are currently underway to identify the cause of this year’s spike.
The MDHHS has also issued guidelines recommending that restaurants and food services in Southeast Michigan focus on selecting whole produce rather than pre-washed, bagged items. Food handlers are urged to wash all produce thoroughly and consider cooking greens, herbs, and berries to help eliminate any potential parasites.
In summary, this peak season—which the CDC designates as running from May 1 to August 31—promises to be particularly concerning this year, given the unprecedented rise in cases and the mystery surrounding their origins.
