Cross-contamination is the physical movement or transfer of harmful bacteria from one person, object or place to another. Preventing cross-contamination is a key factor in preventing foodborne illness.
Minnesota Department of Health Consumer Fact Sheet, Revised April, 2007
>Separate raw meat, poultry, and seafood from other foods in your grocery-shopping cart.
>Place these foods in plastic bags to prevent their juices from dripping onto other foods.
>It is also best to separate these foods from other foods at check out and in your grocery bags.
When refrigerating food:
>Place raw meat, poultry, and seafood in containers or sealed plastic bags to prevent their juices from dripping onto >other >foods. Raw juices often contain harmful bacteria.
>Store eggs in their original carton and refrigerate as soon as possible.
When preparing food:
Keep it clean:
>Wash hands and surfaces often. Harmful bacteria can spread throughout the kitchen and get onto cutting boards, utensils, and counter tops. To prevent this:
>Wash hands with soap and hot water before and after handling food, and after using the bathroom, changing diapers; or handling pets.
>Use hot, soapy water and paper towels or clean cloths to wipe up kitchen surfaces or spills. Wash cloths often in the hot cycle of your washing machine.
>Wash cutting boards, dishes, and counter tops with hot, soapy water after preparing each food item and before you go on to the next item.
>Always use a clean cutting board.
>If possible, use one cutting board for fresh produce and a separate one for raw meat, poultry, and seafood.
>Once cutting boards become excessively worn or develop hard-to-clean grooves, you should replace them.
>Always marinate food in the refrigerator, not on the counter.
>Sauce that is used to marinate raw meat, poultry, or seafood should not be used on cooked foods, unless it is boiled just before using.
Fruits and vegetables:
>Rinse fresh fruits and vegetables in running tap water to remove visible dirt and grime.
>Remove and discard the outermost leaves of a head of lettuce or cabbage.
>Because bacteria can grow well on the cut surface of fruit or vegetables, be careful not to contaminate these foods while slicing them up on the cutting board, and avoid leaving cut produce at room temperature for many hours.
When serving food:
>Always use a clean plate.
>Never place cooked food back on the same plate or cutting board that previously held raw food.
