Cyclospora in Berries: Louisville's Outbreak History & Safety Guide

Cyclospora Outbreaks Linked to Louisville & the Midwest

Cyclospora cayetanensis has caused multistate outbreaks affecting Kentucky and surrounding regions, primarily traced to imported berries from Central and South America where contaminated water is common during growing seasons. The CDC and FDA have investigated several clusters involving raspberries and blueberries distributed through national grocery chains and local markets in Louisville. Louisville Metro Department of Public Health has coordinated with the Kentucky Department for Public Health to notify residents and healthcare providers about implicated products. Symptoms—including severe diarrhea, nausea, and abdominal cramps—can take 7-10 days to appear, making source identification critical.

How Louisville Health Departments Respond

The Louisville Metro Department of Public Health works directly with the FDA and FSIS to trace contaminated produce back to distribution centers and farms. When cases cluster, epidemiologists conduct interviews to identify common food sources and issue public health alerts through local media and the Jefferson County Health Department network. The department coordinates with local hospitals and laboratories to confirm Cyclospora cases using stool samples and genetic sequencing. Response protocols include product recalls coordinated with the FDA, consumer notifications, and guidance for healthcare providers on diagnosis and treatment with antibiotics like trimethoprim-sulfamethoxazole.

Protect Yourself: Consumer Safety & Real-Time Alerts
