Cyclospora Outbreak Response for School Cafeterias

Immediate Actions: First 24 Hours

Upon notification of a suspected Cyclospora outbreak, isolate and stop serving any suspect items immediately—typically fresh produce like lettuce, berries, or cilantro that arrive within the suspected exposure window (typically 7-10 days before illness onset). Contact your local health department and state epidemiology office without delay; they will guide testing and investigation. Secure all product invoices, delivery dates, and supplier information for affected items. Pull Point of Sale (POS) data or meal records to identify which students and staff consumed the suspect meal, enabling targeted notification. Document all actions taken, including time, personnel involved, and specific products removed, as this creates the foundation for your investigation file.

Health Department Coordination & Testing

Work directly with your county or city health department—they have legal authority to investigate foodborne illness clusters and access to CDC epidemiological resources. Provide them with patient contact lists, meal rosters, and produce sourcing documents. The health department will likely request stool samples from ill individuals and may coordinate testing through state public health laboratories (which are part of the CDC's FoodNet surveillance network). Cyclospora is detected via microscopy, so samples must be preserved properly and shipped to a certified lab. Continue communication with the health department daily; they may issue product recalls or supplier holds affecting your area. Follow all their directives, as they have epidemiological expertise and regulatory authority.

Product Tracing, Documentation & Staff Communication

Conduct complete trace-back of the suspected product(s) to suppliers and distributors using invoices, lot numbers, and receiving records. Contact your produce distributors and food suppliers immediately to identify all customers who received the same lot. Retain all original packaging, labels, and documentation in a secure location for health department inspection. Issue a factual, measured communication to staff and families: confirm that illness cases are being investigated, name the suspect food item(s), specify the affected meal date(s), explain what actions you've taken, and provide symptoms to watch for (diarrhea, stomach cramps, loss of appetite appearing 7-10 days after exposure). Establish a dedicated phone line or email for questions. Document all communications sent and received. Implement enhanced cleaning protocols for all food contact surfaces and equipment that may have touched the contaminated product.
