Cross-contamination is a potential risk when preparing a variety of foods. It happens when harmful bacteria from one food, especially raw meat, is transferred to another food. It usually happens when cutting boards, knives, counter tops, and your hands are not washed after handling each food item.
Steps to prevent cross-contamination include:
- When shopping, keep produce and meats separate by putting each in plastic bags. Make sure the grocery bagger keeps them separate as well.
- Always use a clean cutting board. If possible use different boards for fresh produce and raw animal products. Also, do not use excessively worn cutting boards; replace them.
- Wash dishes and counter tops with hot soapy water before and after preparing each food item. When refrigerating food, make sure juices from raw meat and other animal products do not drip onto other foods. Keep them in sealed plastic bags or containers and stored below ready-to-eat food items.
- Wash your hands before and after handling food, allowing about 20 seconds while using soap and warm water.
