Why should food handlers not have painted fingernails?

Food handlers should not have painted fingernails primarily because they may harbor pathogens. The presence of nail polish can create small crevices where dirt and bacteria can accumulate, making it difficult to maintain proper hygiene. When food handlers with painted nails handle food, there is a risk of those pathogens contaminating the food, which poses a significant food safety concern. This is especially critical in a restaurant environment, where the emphasis is on preventing foodborne illnesses.

While it's true that visual appeal and potential distractions can play a role in food handling environments, the main focus for health and safety is preventing contamination. Allergic reactions, although possible, are less of a widespread concern compared to the fundamental issues related to food safety and hygiene associated with pathogen growth on unclean surfaces, including the area beneath painted nails.
