What is the role of handwashing in food safety, and what are the steps for proper handwashing?

• A. Wet hands with warm water; apply soap and scrub for at least 20 seconds, including between fingers and under nails; rinse; dry with disposable towel; turn off faucet with towel
• B. Turn on faucet, wash quickly
• C. Rinse with cold water only
• D. Use sanitizer instead of soap and water

Answer: (A)

Handwashing reduces the microbes you can transfer to food by physically removing dirt, oils, and organisms from the hands. The best practice combines water, soap, thorough scrubbing, rinsing, and careful drying to minimize cross-contamination. Wet your hands with warm water, apply soap, and scrub all hand surfaces for at least 20 seconds, making sure to clean between fingers and under nails where germs hide. Rinse completely to wash away loosened dirt and microbes, then dry hands with a disposable towel and use that towel to turn off the faucet to avoid recontaminating your hands. This sequence provides a reliable, practical way to keep hands clean before handling food and after activities that soil them.

Rushing the wash, using only cold water, or relying on sanitizer alone aren’t sufficient, especially when hands are dirty or greasy. The soap-and-water method physically removes contaminants, while sanitizer cannot replace washing when hands aren’t clean.
