Which of the following is a sign of good food safety practices?

The choice of employees washing hands frequently is a clear indicator of good food safety practices. Frequent handwashing is crucial in preventing the spread of foodborne illnesses. It helps eliminate pathogens that can be transferred to food through hands, which is a common route for contamination. Proper hand hygiene among food handlers not only safeguards the health of consumers but also supports compliance with food safety regulations.

In contrast, the other options reflect poor practices. Storing food at room temperature can lead to the growth of harmful bacteria, cooking food unevenly may result in parts of the food being undercooked, allowing pathogens to survive, and using expired ingredients poses a significant risk as they might harbor dangerous bacteria or toxins. Therefore, regular handwashing directly correlates to maintaining high standards of food safety in any food service operation.
