The Arkansas Department of Health (ADH) has confirmed 10 cases of cyclosporiasis in the state so far in 2026, prompting health officials to remind Arkansans about the importance of proper food handling and produce preparation.
Cyclosporiasis is a parasitic illness caused by Cyclospora cayetanensis. The infection most commonly affects the digestive system and can cause severe or “explosive” diarrhea. While the illness can be unpleasant and sometimes long-lasting, ADH officials say it is not considered life-threatening.
Symptoms Can Last for Weeks
According to the Arkansas Department of Health, symptoms may include:
Explosive diarrhea
Loss of appetite
Weight loss
Stomach pain or cramping
Bloating and excessive gas
Nausea
Extreme fatigue
Vomiting
Body aches
Headache
Fever
Flu-like symptoms
Health officials note that symptoms may improve before returning again, with illness lasting from several days to a month or longer. Diagnosis requires laboratory testing.
Hospitalizations Have Been Limited
The ADH reports that no Arkansas patient has been hospitalized for more than 24 hours because of cyclosporiasis this year. Officials said at least one person was admitted for observation but was discharged in less than 24 hours.
Cases Slightly Higher Than Last Year
Arkansas has confirmed:
10 cases in 2026
7 cases in 2025
11 cases in 2024
Nationwide, the Centers for Disease Control and Prevention (CDC) has recorded 1,645 cases of cyclosporiasis so far this year.
How People Become Infected
Health officials say the parasite has previously been linked to contaminated fresh produce, particularly:
Green leafy vegetables
Raspberries
Unlike many illnesses, cyclosporiasis is unlikely to spread directly from person to person because the parasite must remain outside the body for 1 to 2 weeks before it becomes infectious.
How to Protect Yourself
The Arkansas Department of Health recommends several food safety measures:
Wash your hands before handling fruits and vegetables.
Thoroughly rinse fresh produce.
Scrub firm fruits and vegetables with a clean brush.
Cut away bruised or damaged portions before eating.
Follow safe food-handling practices during preparation.
Cases Across Neighboring States
According to CDC data:
Arkansas: 1–10 cases
Louisiana: 1–10 cases
Tennessee: 11–30 cases
Oklahoma: 11–30 cases
Missouri: No reported cases
Texas: 31–80 cases
New York currently has the nation’s highest reported number of cases, with an estimated 161 to 300 infections.
The Arkansas Department of Health encourages anyone experiencing persistent diarrhea or other symptoms to contact a healthcare provider for evaluation and testing.
