When should food workers wash their hands?

Food workers should wash their hands before handling food and after using the restroom to ensure proper food safety and hygiene. Washing hands before handling food helps to remove any contaminants, bacteria, or viruses that could be transferred to food during preparation or serving, which is crucial in preventing foodborne illnesses.

In addition, handwashing after using the restroom is critical because hands can easily become contaminated with pathogens in that environment. This practice helps to reduce the risk of cross-contamination and keeps both food workers and consumers safe from potential health hazards.

The other options focus on limited handwashing instances that do not encompass the full range of scenarios where handwashing is necessary for food safety. Hand hygiene is a fundamental part of maintaining health standards in any food service operation.
