What temperature should soup be heated to before serving on the buffet line?

For serving soup on a buffet line, it is essential to heat it to a temperature of at least 165°F. This temperature is critical for ensuring food safety, as it effectively kills harmful bacteria and viruses that could cause foodborne illnesses. Heating soup to this temperature also ensures that it remains safe for consumers, particularly when it may sit out for extended periods.

Additionally, reaching 165°F helps to maintain the quality and flavor of the soup, providing a pleasant dining experience. Generally, foods need to be held at or above this temperature to prevent pathogens from growing. It's important for food service establishments to adhere to these guidelines to protect public health and comply with food safety regulations.
