What is the recommended length of time that hands should be washed prior to handling food to prevent disease spread?

Washing hands thoroughly for 20 seconds is the widely recommended duration to effectively remove pathogens and contaminants before handling food. This duration allows adequate time to ensure that all areas of the hands, including between the fingers and under the nails, are cleaned properly. The effectiveness of handwashing in reducing the transmission of foodborne illnesses is well-supported by research, which emphasizes that a longer washing time significantly enhances the removal of harmful microorganisms.

While shorter durations, such as 10 or 15 seconds, might seem adequate for basic cleaning, they are not long enough to ensure thorough sanitization, especially in environments where food safety is paramount. Likewise, washing for 25 seconds, although it may seem more thorough, exceeds the optimal amount of time recommended for balancing effectiveness and practicality in food-handling practices. Consistency in following the 20-second guideline helps promote better hygiene and reduces the risk of foodborne diseases.
