Final answer:
The PIC should ensure that food handlers have their long, loose hair tied back before entering the prep area to prevent food contamination.
Step-by-step explanation:
Before food handlers enter the prep area, the Person in Charge (PIC) should ensure that they are wearing clean uniforms and have taken certain hygiene precautions to maintain a safe food preparation environment. The correct option is d. Long, loose hair tied back. This is essential as it helps prevent hair from contaminating food. While electronic devices, jewelry, and tattoos might concern workplace professionalism or personal expression, they are not primarily hygiene-related issues in the context of food safety. Therefore, food handlers should tie back long hair and also adhere to other practices like wearing closed shoes with flat heels and ensuring proper handwashing. These protocols are critical in preventing the spread of foodborne diseases and ensuring a safe working and dining experience.
