What is one of the most important thing you can do to fight food poisoning? Here are a few hints:
It takes only 20 seconds (if you do it the right way).
It requires only 3 ingredients.
Anyone can do it, even very young children.
The answer is Wash Your Hands. Over and over again, studies have shown that handwashing is one of the most effective ways to prevent the spread of many types of infection and illness–including foodborne illness.
Wash Your Hands the Right Way
When you wash your hands the right way, it takes only 20 seconds and requires only three ingredients: running water, soap, and something to dry your hands (a clean towel or air).
Here’s how to do it:
Wet your hands with clean running water (warm or cold) and apply soap.
Rub your hands together to make a lather and scrub them well; be sure to scrub the backs of your hands, between your fingers, and under your nails.
Continue rubbing your hands for at least 20 seconds. Need a timer? Hum the “Happy Birthday” song from beginning to end twice.
Rinse your hands well under running water.
Dry your hands using a clean towel or air dry.
And here’s when to do it:
Before, during, and after preparing food
Before eating food
After using the toilet
After changing diapers or cleaning up a child who has used the toilet
Before and after caring for someone who is sick
After blowing your nose, coughing, or sneezing
After touching an animal or animal waste
After touching garbage
Before and after treating a cut or wound
What About Hand Sanitizers?
Washing hands with soap and water is the best way to reduce the number of germs on them. But, if soap and water are not available, use a hand sanitizer.
Important: Hand sanitizers are not effective if your hands are visibly dirty.
Alcohol-based hand sanitizers can quickly reduce the number of germs on hands in some situations, but sanitizers do not eliminate all types of germs.
Always use an alcohol-based hand sanitizer that contains at least 60% alcohol. Here’s how to use hand sanitizer properly:
Apply the product to the palm of one hand.
Rub your hands together.
Rub the product over all surfaces of your hands and fingers until your hands are dry.
