What is the proper technique for handwashing?

• A. Wash for at least 10 seconds with soap
• B. Use only water without soap
• C. Wash with soap and water for at least 20 seconds
• D. Rinse hands without soap

Answer: (C)

The correct answer emphasizes the importance of washing hands with soap and water for at least 20 seconds. This duration is crucial because it allows enough time for soap to effectively remove dirt, germs, and viruses from the skin. The mechanical action of scrubbing, combined with the surfactants in the soap, breaks down and dislodges contaminants. It’s widely recommended by health organizations, including the Centers for Disease Control and Prevention (CDC), that 20 seconds is the minimum duration for effective handwashing to ensure that hands are properly cleaned. In contrast, washing for only 10 seconds may not provide adequate time to remove all pathogens effectively. Using only water without soap fails to effectively eliminate germs, rendering the handwashing process ineffective. Similarly, rinsing hands without soap does not remove contaminants and poses a risk of spreading germs. Thus, the combination of soap, water, and the recommended duration significantly enhances the effectiveness of handwashing in reducing the risk of foodborne illness and the spread of infections.
