What action must be taken to prevent bare hand contact in food treatment?

To effectively prevent bare hand contact in food treatment, a comprehensive approach that includes multiple actions is required. Using gloves when handling food is crucial as it acts as a physical barrier between the hands and food, thus reducing the risk of contamination. Washing hands frequently is equally important as it ensures that any potential pathogens present on the hands are removed, maintaining food safety standards. Additionally, monitoring staff health helps to ensure that employees are not working while ill, further reducing the risk of contaminating food with germs. Therefore, the combination of these actions—using gloves, ensuring proper handwashing, and monitoring health—forms a robust strategy to minimize the risk of bare hand contact with food, making the answer encompassing all these practices the most effective choice.
