How long should food handlers wash their hands?

1. 30 seconds

2. 20 seconds

3. 3 minutes

4. 1 minute

The correct answer is: 20 seconds

Food handlers should wash their hands for at least 20 seconds to effectively remove germs, dirt, and food residues. This duration is supported by research and guidelines from health authorities, as it allows enough time to ensure thorough cleaning, particularly when using soap and running water. The 20-second recommendation is particularly important as it aligns with findings that shorter washing durations, such as 10 seconds or less, may not be sufficient to provide adequate microbial reduction. By washing for a full 20 seconds, food handlers can significantly decrease the risk of foodborne illnesses caused by the transfer of pathogens from hands to food. Relying on this standard helps ensure compliance with health regulations and promotes safe food handling practices in a kitchen or food service environment.
