What must food handlers avoid wearing to maintain food safety?

Food handlers need to maintain a high level of personal hygiene and prevent any potential contaminants from coming into contact with the food. Wearing makeup can pose a risk because it may flake off or slip into the food, which can lead to physical contamination. Additionally, makeup can harbor bacteria and other pathogens, compromising the food safety standards that food handlers must strictly adhere to.

In contrast, other choices like headbands, watches, and hair nets are not inherently unsafe when it comes to food handling. Hair nets are actually required to keep hair contained and prevent it from falling into food, while headbands and watches do not directly increase the risk of contamination, as long as they are kept clean and do not interfere with the handling of food.
