Using the same knife to chop carrots for a salad immediately after cutting up raw chicken is an example of what?

This is an example of cross-contamination.

Here's why:

* Raw chicken carries bacteria: Raw chicken can harbor harmful bacteria like Salmonella and Campylobacter.

* Knife transfers bacteria: When you use the same knife to chop carrots after cutting raw chicken, you transfer these bacteria from the chicken to the carrots.

* Potential illness: If you eat the raw carrots, you can become sick from these bacteria.

To prevent cross-contamination:

* Use separate cutting boards: One for raw meat and another for produce.

* Wash knives and cutting boards thoroughly: Use hot, soapy water to clean them after each use.

* Wash your hands: Wash your hands thoroughly with soap and water after handling raw meat.
