Parasite Lurks in Produce: Is Anything Safe?
13 Jul
Summary
- No fresh produce is entirely risk-free from the cyclospora parasite.
- Hundreds of cyclosporiasis cases are under investigation across the US.
- Thick-skinned fruits and cooked vegetables are considered lower risk.
Health officials are investigating a surge in cyclosporiasis cases across the United States, prompting consumer concerns about the safety of fresh produce. Hundreds of confirmed cases have been reported in at least 31 states, with symptoms including fatigue and severe diarrhea. The illness is caused by the parasite Cyclospora cayetanensis, which contaminates food or water through human fecal matter.
While no raw fruits or vegetables are completely risk-free, experts suggest lower-risk options. These include fruits with thick, inedible peels like bananas, citrus, avocados, pineapples, watermelons, and mangoes. Cooking produce thoroughly is also an effective safeguard, making items like corn, green beans, peas, and squash safer than their raw counterparts. Washing produce under running water and refrigerating cut items are recommended practices to reduce exposure.
The canning process, which uses heat, significantly reduces the risk associated with fruits and vegetables. Previous outbreaks have been linked to various produce, including bagged salads, cilantro, raspberries, and basil. Although the specific source of the current outbreak has not yet been identified, public health agencies continue to emphasize that eating fruits and vegetables remains vital for a healthy diet.
