Which single symptom, reported by a food handler, requires the manager to EXCLUDE (not just restrict) that employee from the operation?

解析

An employee with vomiting or diarrhea must be excluded from the operation because these symptoms strongly signal a transmissible foodborne pathogen. A restriction (keeping the person away from food and clean equipment) applies to lesser situations, such as a sore throat with fever in an operation serving the general public. Irritated eyes, a seasonal cough, and a headache are not symptoms the Food Code ties to foodborne transmission, so on their own none of them requires exclusion or restriction.
