According to experts from the Food Safety and Inspection Service (FSIS), a branch of the USDA, 99 percent of people do not wash their hands properly. FSIS authorities warn that this presents a serious problem when it comes to food preparation, because the kitchen is known to spread dangerous germs, including Salmonella, Campylobacter, E. coli, Listeria, and more. “Cleanliness is a major factor in preventing food-borne illness,” says the FSIS site. The Centers for Disease Control and Prevention (CDC) also touts the importance of the practice, calling it “one of the most important things you can do to prevent food poisoning when preparing food for yourself or loved ones.” “Your hands can spread germs in the kitchen. Some of these germs, like Salmonella, can make you very sick. Washing your hands frequently with soap and water is an easy way to prevent germs from spreading around your kitchen and to other foods,” their experts say.

The CDC says that the key to sufficient hand washing is to scrub for at least 20 seconds with warm, soapy water, wetting your hands first to work up a good lather. “Scientific studies show that you need to scrub for 20 seconds to remove harmful germs and chemicals from your hands. If you wash for a shorter time, you will not remove as many germs. Make sure to scrub all areas of your hands, including your palms, backs of your hands, between your fingers, and under your fingernails,” their experts advise. After rinsing your hands clean under running water, be sure to dry your hands on a clean towel or with a touch-free air dryer. If your sink handle hasn’t been cleaned in a while, you can use “a paper towel, your elbow, or another hands-free way” to turn off the water without re-contaminating your hands, suggests the CDC. The USDA and CDC both say there are a few key scenarios in which washing your hands is non-negotiable. If you stop to wash in these moments, you can minimize the risk of spreading dangerous germs and contaminants.ae0fcc31ae342fd3a1346ebb1f342fcb First and foremost, be mindful to wash your hands before and after handling food (especially uncooked eggs, raw meat, poultry, or fish). The health authority also recommends giving them a 20-second scrub after using the bathroom, changing diapers, handling pets and their bowls, tending to a sick individual, and after blowing your nose, coughing or sneezing. When in doubt, there’s virtually never a harm in washing your hands an extra time during food preparation—especially when you’re preparing meals for others.

Experts at Insider say that this could lead to serious health consequences, as germs spread readily in the kitchen when we neglect to wash our hands. “Diarrhea-causing illnesses, like salmonella or giardiasis, are 30 percent more likely when you don’t wash your hands,” the publication notes. “You are 20 percent more likely to catch respiratory viruses, like influenzas, the common cold, and, of course, COVID-19, potentially leading to complications or even severe pneumonia. And then there’s the norovirus. This severe stomach virus only needs a single particle to infect you. Influenzas need 50 to 100. So without hand washing, you’re almost guaranteed to catch it sooner or later,” Insider says. The next time you make a meal, take a 20-second timeout before and after to give your hands a good scrub.
