This video from Southwest Yard and Garden tells viewers why it is important to wash your hands after gardening, and when and how to do so. It also emphasizes the importance of cleaning cutting boards. You should wash your hands before eating, after using the bathroom, and while you are handling food. While handling food, if you handle any meat, you must wash your hands before touching anything else. You should wash your hands for twenty seconds, with soap and water. To demonstrate the importance of washing your hands and avoiding cross-contamination, the two hosts in the video do a demonstration with iridescent dye and a black light. You should also wash both of your cutting boards (one for meat, the other for other foods) after use. To do this properly, wash them separately in warm, soapy water, then rinse them. Then, you need to dip them in a solution of bleach and water; use one quart of water per one tablespoon of bleach. Allow them to air-dry. These tips will keep your food from being cross-contaminated.
