Lincoln, NE – As cyclosporiasis cases continue to rise nationwide, the Nebraska Department of Health and Human Services is reminding residents of the importance of routine food safety practices.
Since May 2026, Nebraska has reported 49 cases of cyclosporiasis. At this time, there have been no reported cases of cyclosporiasis in Nebraska related to the recent outbreak in the United States. DHHS is working with federal and local public health partners to investigate a number of domestically acquired cases to determine if there are shared exposures linking cases together.
“Cyclosporiasis is not a new infection. Nebraska sees a small number of seasonal cases each year between May and September, typically associated with international travel,” said Dr. Timothy Tesmer, DHHS Chief Medical Officer. “Nebraskans who develop symptoms lasting more than three days should contact a healthcare provider. Early diagnosis and treatment can help shorten the illness and reduce the risk of dehydration and other complications.”
Cyclosporiasis is an intestinal illness caused by the Cyclospora parasite, which is typically spread through contaminated food or water, most commonly fresh fruits and vegetables. Previous outbreaks have been linked to bagged salad mixes, fresh cilantro, fresh basil, raspberries, snow peas, and green onions. It is not spread from person to person. Symptoms usually develop about one week after exposure and include watery diarrhea, fatigue, loss of appetite, weight loss, bloating, stomach cramps, and nausea. Without treatment, it can last for weeks or longer, and symptoms may come and go.
Reduce Your Risk:
- Cook foods when possible. Heating food to at least 158°F (70°C) kills the Cyclospora parasite.
- Wash all fresh fruits and vegetables thoroughly under clean, running water before eating, cutting, or peeling them. Scrub firm produce such as melons and cucumbers with a clean produce brush.
- Clean and sanitize your hands, cutting boards, utensils, countertops, and other food preparation surfaces before and after handling fresh produce.
- Cut away any damaged or bruised areas before preparing or eating fruits and vegetables.
- Refrigerate cut, peeled, or cooked fruits and vegetables promptly.
Treatment
People experiencing gastrointestinal illness, such as sudden or ongoing diarrhea lasting more than three days, are encouraged to contact their health care provider. Cyclosporiasis is treated with antibiotics along with rest and drinking plenty of fluids to maintain hydration. Additionally, if you are sick with cyclosporiasis, local or state health officials may contact you to ask about what you ate in the two weeks before becoming sick.
