Which of the following is important for personal hygiene in food handling?

Maintaining personal hygiene is crucial in food handling to prevent foodborne illnesses and ensure a safe environment for food preparation. Keeping hair tied back and wearing clean clothing are essential components of personal hygiene because they help minimize the risk of contaminants being transferred to food. Loose hair can fall into food, potentially carrying bacteria or other pathogens, while clean clothing reduces the likelihood of bacteria or dirt being introduced into the food preparation area.

Other options do not align with best practices for personal hygiene in food handling. Wearing gloves at all times might give a false sense of security if the gloves are not changed properly or if handwashing is neglected. Washing hands only when visibly soiled does not meet the gold standard of frequent handwashing, particularly before handling food, after using the restroom, or after touching any potentially contaminated surfaces. Additionally, wearing fragrances is not advisable, as they can mask odors, but they don't address the underlying cleanliness and hygiene that is paramount in food safety.
