How to Combat the Spread of Cyclospora Outbreaks in Retail Foodservice
Cyclospora poses a significant threat to foodservice operations, and outbreaks continue to challenge the retail foodservice industry, particularly during peak summer produce season. This microscopic parasite presents a unique challenge in food safety and underscores the critical need for robust food sourcing, preparation, and sanitation protocols.
While well-designed cleaning products effectively remove dirt, debris, and organic matter from surfaces, thereby creating a clean environment, these solutions do not directly kill the Cyclospora parasite. Cyclospora is also not killed by common sanitizers or disinfectants. There are currently no EPA approved registered products for cyclospora for this use. Consequently, the primary control strategy is reducing contamination thorough washing to physically remove and flush away the oocysts and cooking produce to at least 158°F.
Key Recommendations for Mitigating Cyclospora Spread Risk:
- Source Control: Purchase produce exclusively from approved suppliers adhering to GAP/GMP standards. Regularly check FDA and CDC alerts for high-risk items like lettuce, cilantro, basil, and berries. Reject any damaged or improperly cooled produce.
- Produce Handling: Thoroughly wash all produce under running potable water, scrubbing firm items to remove potential contaminants. Always keep raw produce separate from ready-to-eat foods, utilizing dedicated equipment to prevent cross-contamination. Properly store cut produce, and when feasible, cook produce to at least 158°F. Note that while effective, produce washing alone does not guarantee the complete removal of all Cyclospora oocysts (the parasite's eggs); thus, a combination of thorough produce washing and cooking provides the best protection.
- Employee Hygiene & Training: Educate staff on Cyclospora symptoms and reinforce stringent handwashing practices, especially after handling raw produce or using the restroom. Encourage prompt reporting of illness.
- Cleaning & Sanitation: Cyclospora oocysts are notoriously "sticky" and cling heavily to plastic cutting boards, prep sinks, and slicer blades. Using a strong detergent has the potential to lift these organic matter traps, physically removing the parasite from the surface and preventing it from hitchhiking onto the next batch of raw produce. Follow proper FDA food preparation protocols for cleaning and sanitization to help minimize the likelihood of cross-contamination.
- Outbreak Response: In the event of an outbreak, immediately cease using implicated produce, isolate affected lots, and conduct a deep clean of all produce prep areas.
