HUMAN NUTRITION

Detailed explanation-1: -For example, if you cut up a raw chicken, and then use the same cutting board to slice a tomato for your salad, you run the risk of cross-contamination – with bacteria from the chicken being transferred to the tomato.

Detailed explanation-2: -Food to Food Here are some examples of food-to-food cross-contamination: In a refrigerator, meat drippings from raw meat stored on a top shelf might drip onto cooked vegetables placed on lower shelf. Raw chicken placed on a grill touching a steak that is being cooked.

Detailed explanation-3: -If you cut raw meat on a chopping board, bacteria will spread from the meat to the board and knife. If you then use the same board and knife (without washing them thoroughly) to chop a cucumber, the bacteria will spread from the board and knife to the cucumber. Hands can also spread bacteria.
