How to reduce your risk
Health officials recommend the following steps when handling fresh produce:
- Wash your hands before and after handling fruits and vegetables.
- Clean and sanitize cutting boards, knives and food preparation surfaces.
- Scrub firm produce, such as melons and cucumbers, with a clean produce brush.
- Remove bruised or damaged areas of produce.
- Rinse fresh produce thoroughly under running water before eating.
- Refrigerate cut, peeled or cooked fruits and vegetables promptly.
- Cook food when possible, as heat can kill the parasite.
When to seek medical care
Cyclosporiasis is usually not life-threatening, but severe diarrhea can cause dehydration, particularly among older adults, young children and people with weakened immune systems.
Anyone experiencing persistent diarrhea, signs of dehydration, severe abdominal pain or symptoms lasting more than several days should contact a health care provider.
