Cold-Holding Failure During a Community Event
A hospital's catering department prepared 600 boxed lunches for a community health fair. Sandwiches with sliced turkey and cheese were assembled at 6 a.m., held in insulated coolers, and served from 11 a.m. to 2 p.m. outdoors in 88°F weather. At 1:30 p.m., a volunteer reports the coolers feel warm and several sandwiches are 'sweating.' An estimated 180 boxes remain unserved. The catering supervisor must decide what to do with the remaining food and how to respond. No one has become ill yet, and the event organizer wants to keep serving until 2 p.m.
1. Evaluate the food safety risk and decide what to do with the remaining 180 boxes.

The product is a time/temperature control for safety food containing turkey and cheese. Once assembled and held above 41°F, it accumulates time in the temperature danger zone. With outdoor heat at 88°F and coolers that are no longer cold, the sandwiches have almost certainly exceeded safe holding limits; the 'sweating' suggests condensation from warm air contacting cold product, and the warm cooler walls indicate the cold source has failed.
Without temperature logs, the supervisor cannot demonstrate the product stayed below 41°F. The conservative, defensible decision is to discard the remaining 180 boxes and stop service. The cost of 180 lunches is trivial against a foodborne illness outbreak among community members, many of whom may be older or immunocompromised. The supervisor should not rely on the absence of illness so far, because onset can lag hours to days. Document the decision, the estimated holding times, and any temperature readings taken with a calibrated thermometer.
2. Outline the corrective actions and the communication the supervisor should make.

Immediate: stop service, segregate and label the product 'do not serve,' discard, and record the discard. Take and log temperatures of any remaining product and cooler interiors. Notify the event organizer and the department director.
Communication: tell the organizer plainly that the food cannot be served for safety reasons and offer an alternative (e.g., sealed shelf-stable items) if available. Prepare a brief statement for attendees if questions arise. Notify infection prevention and the local health authority per policy if any illness is later reported.
Corrective actions:
- Require temperature logs at assembly, at departure, and every 2 hours during service.
- Use sufficient ice or gel packs and pre-chill coolers; keep coolers shaded and closed.
- For outdoor events above 70°F, set a 4-hour maximum from assembly to discard and build in a mid-event temperature check.
- Reduce batch size so product is not held all day.
- Train volunteers on the rule that warm product is discarded, not 'rescued.'
