Arkansas Department of Health reports Cyclosporiasis in two north central Arkansas counties

The Arkansas Department of Health has confirmed an increase in cases of Cyclosporiasis across the state, with new reports emerging in north central Arkansas. Officials identified 79 total cases within the state boundaries for 2026. While the majority of these infections are concentrated in Benton County, Marion and Boone counties have also documented cases.

Cyclosporiasis is an intestinal illness caused by the Cyclospora cayetanensis parasite. Infection occurs after consuming food or water contaminated with the parasite. Health experts state that while the condition is rarely life-threatening, it causes watery, sometimes explosive diarrhea that can persist or return after a period of improvement.

State health investigators are tracking the source of the outbreak. Current efforts focus on shredded iceberg lettuce distributed by Taylor Farms in central Mexico. Although the FDA previously removed a positive lab result linked to this supplier, it remains a primary point of interest in the ongoing investigation.

Medical professionals recommend a standard treatment involving trimethoprim-sulfamethoxazole for those affected. Patients are advised to focus on rest and hydration. Individuals with healthy immune systems typically recover without medical intervention, but symptoms may continue for a month if left untreated. People in poor health face a higher risk of severe or prolonged illness.

To reduce infection risks, residents should wash their hands thoroughly before preparing food. All produce requires careful rinsing under running water, and damaged portions of fruits or vegetables should be discarded before preparation. Cut or prepared produce needs refrigeration within two hours. While outbreaks typically occur during warmer months, current data indicates a higher frequency of cases this year compared to previous years.
