USDA: Most people wash their hands wrong, cross contaminating



(Meredith / USDA) – A new study by the US Department of Agriculture shows that hand washing before meals fails to clean hands 97 percent of the time. Rushed hand washing can lead to cross-contamination of food and other surfaces, leading to food-borne illnesses.

"As the mother of three young children, I am very familiar with the frenzied beat that families go through to put food on the table," said Carmen Rottenberg, Deputy Undersecretary for Food Security at the USDA. "You can not see, smell, or feel bacteria, just by washing your hands properly, you can protect your family and prevent bacteria from contaminating your food and key areas in your kitchen."

With the barbecue season, the USDA recalls using a food-grade thermometer to cook meat and poultry products at recommended indoor temperatures. When cooking meat and chicken patties, insert the thermometer through the side of the patty until the probe reaches the center of the patty. Meat and poultry products are produced when this minimum internal temperature is reached:

  • Beef, pork, lamb and veal (steaks, roasts and chops): 145 ° F
  • Minced meat (burgers): 160 ° F

    • 19659006 ] Poultry (whole or ground): 165 ° F

    After handling raw meat, poultry or eggs, wash hands thoroughly with soap and water. Make sure you wash for a full 20 seconds, and always dry your hands with a clean towel.
