360 Training Food Handlers Practice Exam

Which of the following is a key indicator of good handwashing practice?

1. Using warm water only

2. Washing for at least 20 seconds

3. Drying hands on tablecloths

4. Using antibacterial soap exclusively

The correct answer is: Washing for at least 20 seconds

Washing hands for at least 20 seconds is a key indicator of good handwashing practice because research has shown that duration plays a crucial role in effectively removing germs and pathogens from the hands. Thorough washing removes dirt, grease, and microorganisms that may be present. The act of rubbing hands together, combined with this time duration, helps to dislodge bacteria and viruses from the skin and ensures they are rinsed away completely. In addition, the Centers for Disease Control and Prevention (CDC) recommends this duration as an essential part of proper handwashing to reduce the risk of foodborne illnesses and infections. While using warm water promotes comfort and can facilitate lathering, and soap can enhance germ removal, simply using warm water alone or relying only on antibacterial soap does not guarantee effectiveness without the adequate duration of washing. Furthermore, drying hands on tablecloths is unhygienic, as it can lead to cross-contamination, undermining the effectiveness of the handwashing effort.
