After Cutting Raw Meat with a Knife Set

You should always clean and sanitize your knife set after cutting meats like chicken, beef, or fish. Raw meat can leave bacteria on the blade. This bacteria can get onto other foods. Wash your knives by hand using hot, soapy water right after you use them. Use a bleach solution to sanitize the knife. Let it sit for a few minutes before rinsing. Dry the knife with a clean towel or let it air dry. Every chef knife, boning knife, or utility knife used for raw meat needs this step. Cleaning and sanitizing after cutting meats helps stop foodborne illness.

Tip: Do not stack dirty knives in the sink. Wash each knife right away to stop accidents and cross-contamination.


Between Preparing Different Foods with a Knife Set

When you switch from one food to another, you need to clean and sanitize your knives. This is very important if you go from allergens or raw meat to vegetables. For example, after slicing bread with a bread knife, clean it before you chop vegetables. This keeps allergens and bacteria from spreading between foods. Cleaning and sanitizing between tasks is a good habit at home and in restaurants.


Before Storing Your Knife Set

Always clean and sanitize your knives before putting them away. Even if a knife looks clean, it can still have bacteria you cannot see. Studies show that knives can spread germs like E. coli and Salmonella to new foods if not cleaned well. Just wiping with a towel is not enough. Wash, rinse, and air dry your knife set before putting them back in the knife block or drawer. This keeps your kitchen safe and your knives in good shape.
