Final answer:
Food handlers with sore throat and fever should be excluded from operations, especially in high-risk environments, until symptoms cease to stop the spread of foodborne illness.
Step-by-step explanation:
A food handler with a sore throat and fever should be excluded from an operation to prevent the potential spread of foodborne illnesses. In particular, for establishments that serve a high-risk population, such as hospitals and schools, exclusion is mandatory until symptoms have ceased.
Health codes typically require that food handlers with these symptoms are not involved in the preparation or serving of food to avoid the risk of transmitting illness to others. This precaution aligns with the general expectations to stay home and rest if one is experiencing such symptoms, and to see a doctor if they persist beyond 48 hours. Regular handwashing and proper food safety protocols are vital in minimizing the risk of foodborne diseases spread.
