E. coli O157:H7 Outbreak Response Guide for Food Co-ops

Immediate Actions: First 24 Hours

The moment you receive notice of a potential E. coli O157:H7 contamination—whether from the FDA, FSIS, or your local health department—quarantine all affected products immediately and prevent sale or distribution. Notify your management team, food safety officer, and legal counsel within 1-2 hours; do not delay. Call your local health department's food safety division to report the situation and ask for guidance on product scope, customer notification timeline, and any required testing. Pull all point-of-sale records to identify which customers purchased the affected product and when, and secure any remaining inventory in a designated quarantine area with clear labeling.

Staff Communication & Customer Notification

Brief all staff—especially checkout and produce teams—with a factual statement of the outbreak, the specific products involved (UPC, lot codes, date ranges), symptoms to watch for, and a clear directive to remove items from shelves immediately. Prepare a customer-facing statement that identifies the product by brand and lot code, explains the health risk, lists symptoms of E. coli O157:H7 infection (bloody diarrhea, severe stomach cramps, kidney failure in severe cases), and directs customers to discard the product or return it for a refund. Post notices at store entrances and on your website; send emails or texts to loyalty program members who purchased the product within the relevant timeframe, and alert local media if the health department recommends it.

Health Department Coordination & Documentation

Establish daily communication with your local health department's investigator assigned to the outbreak; they will guide trace-back efforts to identify the supplier source and forward-trace to identify all customers. Comply fully with all requests for inventory records, supplier information, temperature logs, and storage documentation. Maintain a detailed incident log documenting the date and time of notification, all products affected, quarantine actions, staff communications, customer notifications, and conversations with health officials. Preserve all documentation for at least 2 years; the FDA and state attorneys general may request records as part of their investigation. Do not destroy or alter any records, and consult your legal counsel before making public statements beyond the approved customer notice.
