Health authorities in the United States are monitoring a rise in infections caused by the parasite Cyclospora, which has been linked to contaminated fresh produce and can trigger prolonged diarrheal illness.
According to the US Centers for Disease Control and Prevention (CDC), 145 laboratory-confirmed cases were reported across 17 states between May 1 and June 16. At least 20 people have been hospitalised, although no deaths have been reported.
Cyclospora is a microscopic parasite that can contaminate fresh fruits and vegetables. Infection, known as cyclosporiasis, commonly causes severe diarrhea, stomach cramps, nausea, fatigue, loss of appetite and weight loss. Symptoms may last for several weeks if left untreated.
Health officials say warmer summer conditions can contribute to an increase in Cyclospora cases, making the parasite more common during this time of year. The CDC advises consumers to thoroughly wash fresh produce before eating it, although washing alone may not always eliminate the parasite.
Among the affected areas, Michigan has reported a significant increase in cases. State health officials said nearly 170 infections had been identified in just over a month, with cases concentrated in seven counties. The figures released by Michigan have not yet been fully reflected in the CDC’s national tally.
New York State has also reported an increase, recording 107 cases outside New York City since May 1. Health authorities noted that the state typically reports between 500 and 700 cases annually.
Federal and state investigators have not identified a single multistate outbreak linking all reported infections. Instead, officials are examining possible clusters to determine whether different contaminated food sources are responsible.
The CDC continues to work with state health departments to trace the origins of infections and identify any common food items associated with the cases. Public health authorities have encouraged people experiencing persistent diarrhea after consuming fresh produce to seek medical attention promptly.
