Which of the following is an essential step in washing hands properly?

Scrubbing hands for at least 20 seconds is crucial for effective handwashing. This duration is essential because it allows sufficient time for the soap to break down dirt, grease, and microbes that accumulate on the hands. The mechanical action of scrubbing, combined with soap, helps to dislodge pathogens and contaminants from the skin's surface. Research has shown that washing hands for at least 20 seconds significantly reduces the presence of harmful bacteria and viruses, thereby lowering the risk of foodborne illness and cross-contamination in food service settings. Proper handwashing technique is a key element in food safety practices and is emphasized in training programs to ensure safe food handling.
