Cyclospora Prevention Guide for Louisville Food Service

Produce Sourcing and Water Safety Protocols

Cyclospora is typically transmitted through contaminated water used in produce cultivation or washing. The FDA's Produce Safety Rule requires documented water testing for farms supplying to food service operations. Louisville food service establishments should verify that suppliers maintain water quality certifications and request documentation of water testing for high-risk produce including berries, lettuce, and cilantro. Wash all produce thoroughly under running water—the CDC recommends at least 15-20 seconds of friction washing for leafy greens. Consider sourcing from suppliers enrolled in third-party food safety certification programs (GFSI-recognized), and maintain records of produce shipment dates and origins to support trace-back investigations if an outbreak occurs.

Employee Health Screening and Sanitation Requirements

The Louisville-Metro Department of Public Health & Wellness enforces employee health policies requiring staff to report gastrointestinal symptoms including diarrhea, which is the primary sign of Cyclospora infection. Implement daily health attestations before shifts, especially for employees handling ready-to-eat produce. Establish a policy requiring employees to remain off-duty for at least 24 hours after diarrhea symptoms resolve, and encourage staff to seek medical evaluation if symptoms persist beyond a few days. Require proper handwashing with soap and warm water for at least 20 seconds, particularly after restroom use and before food handling. Train all staff on cross-contamination prevention, as Cyclospora can survive on hands and surfaces if sanitation is inadequate.

Monitoring, Documentation, and Regulatory Compliance

Establish a documented sanitation schedule for all food contact surfaces, with particular attention to produce preparation areas. The Louisville health department expects food service establishments to maintain cleaning logs showing frequency and sanitizer concentrations. Use an approved sanitizer (chlorine, quaternary ammonium, or iodine) at FDA-recommended levels and verify effectiveness through ATP testing or sanitizer test strips. Real-time food safety monitoring platforms like Panko Alerts track FDA and CDC outbreak announcements, allowing Louisville operators to quickly identify affected produce lots and remove them from inventory.
