What personal hygiene practice is critical before handling food?

Washing hands thoroughly is a critical personal hygiene practice before handling food because it effectively removes dirt, bacteria, and pathogens that can be present on the hands. This practice helps to prevent cross-contamination and foodborne illnesses, ensuring that any contaminants from the environment or prior activities do not transfer to the food being prepared or served.

Handwashing should be done using soap and clean, running water for at least 20 seconds, focusing on all areas of the hands, including between the fingers and under the nails. While wearing gloves and using hand sanitizer are also important components of food safety, they should complement proper handwashing rather than replace it. Gloves can become contaminated just like hands can, and hand sanitizer is not as effective at removing all types of pathogens and is not a substitute for thorough handwashing. Brushing teeth, while important for overall hygiene, is not relevant in the context of food handling and does not contribute to food safety in the same manner as handwashing.
