I know you’re probably saying there’s no way this could be true, but it probably is. The crumbs, and food residue you rinse off your dirty plates serve as a breeding ground for bacteria. If you work with poultry in the sink it could be contaminated with Salmonella. Ground meat, and you’re looking at E Coli. Garbage disposals with their moving parts get food particles stuck in them. Solve this by wiping your sink down with a foaming disinfectant cleaner. You can also mix up bleach, and water to pour down the drain. Don’t forget to pay special attention to the drain, and the drain plug. Wash your hands thoroughly before and after handling food. Proper hand washing should last 20 seconds with vigorous scrubbing of the hands.
