Under what circumstance should a food establishment manager send an employee home?

Sending an employee home who shows symptoms of diarrhea is essential for food safety and the prevention of foodborne illnesses. Diarrhea can be a sign of infections that are transmissible through food, posing a risk to customers and other staff members. In food establishments, it's crucial to uphold strict hygiene and health standards to ensure the safety of the food being prepared and served. When an employee exhibits symptoms associated with gastrointestinal illnesses, they should be sent home to prevent contamination and to allow for recovery.

Other circumstances, while relevant, do not necessarily directly impact food safety to the same extent. For instance, a mere request for a day off does not relate to health or hygiene; arriving late is usually a management issue rather than a public health concern; and while a headache can affect performance, it isn’t indicative of an infectious condition that would warrant immediate removal from the workspace. Hence, focusing on symptoms like diarrhea is critical in a food service environment to maintain health standards and protect the well-being of all involved.
