The Correct Handwashing Procedure: A Step-by-Step Guide

Washing hands effectively requires more than just a quick rinse under water. The following steps outline the proper handwashing procedure:

1. Wet Hands: Use clean, running water. The water should be warm, if possible.
2. Apply Soap: Use a generous amount of soap to cover all surfaces of your hands. Antibacterial soap is preferred, but regular soap is also effective.
3. Lather Thoroughly: Rub your hands together vigorously for at least 20 seconds. Make sure to lather the backs of your hands, between your fingers, and under your fingernails.
4. Scrubbing Time:
   • Palm to Palm: Rub palms together in a circular motion.
   • Backs of Hands: Rub each palm over the back of the other hand with fingers interlaced.
   • Between Fingers: Interlace fingers and rub back and forth.
   • Fingertips: Clasp fingers of one hand into the palm of the other and rub in a circular motion to clean under the fingernails.
   • Thumbs: Rub each thumb in a rotating manner, clasped in the opposite hand.
   • Wrists: Don't forget to wash your wrists.
5. Rinse Well: Rinse your hands thoroughly under clean, running water to remove all traces of soap.
6. Dry Hands: Dry your hands with a clean, disposable paper towel. Do not use cloth towels, as they can harbor bacteria.
7. Turn Off Faucet: Use the paper towel to turn off the faucet to avoid recontaminating your hands.
8. Use Hand Sanitizer (Optional): After drying your hands, you can use an alcohol-based hand sanitizer for extra protection. Make sure the sanitizer contains at least 60% alcohol.

Handwashing Facilities: Essential Requirements

Providing adequate handwashing facilities is essential for ensuring that food handlers can practice proper hygiene. Handwashing facilities should be:

• Conveniently Located: Easily accessible in food preparation areas.
• Equipped with Hot and Cold Running Water: Providing water at a comfortable temperature is crucial for effective handwashing.
• Supplied with Soap: Provide a readily available supply of soap, preferably in a dispenser to avoid contamination.
• Equipped with Drying Devices: Provide disposable paper towels or a hand dryer for drying hands.
• Clean and Well-Maintained: Regularly cleaned and sanitized to prevent the buildup of bacteria.
• Clearly Marked: Signage should clearly indicate that the area is for handwashing only.

The Role of Gloves in Food Safety

While gloves can provide an additional barrier between hands and food, they are not a substitute for proper handwashing. Gloves should be used:

• When Handling Ready-to-Eat Foods: To prevent direct contact with bare hands.
• If You Have Cuts or Sores on Your Hands: To protect the food from contamination and your hands from further irritation.
• According to Regulations: Some jurisdictions require the use of gloves for specific tasks.

It's important to remember that gloves can become contaminated, so they should be changed:

• Between Tasks: Especially when moving from a potentially contaminated task to a cleaner one.
• When Torn or Damaged: Immediately replace gloves that are torn or damaged.
• At Least Every Four Hours: Even if they appear clean.
• After Interruptions: Such as answering the phone or handling money.
