How to Prevent Cross Contamination in Food Handling

When bacteria or other microorganisms are transferred from one substance to another, unintentionally, the process is called cross-contamination. Cross-contamination may have harmful effects as it transfers harmful bacteria, and when they reach the other substance, they contaminate it too.

In the given scenario, George cut raw meat with a large knife and then used the same knife to chop vegetables, without cleaning it in between. This action led to cross-contamination, as the bacteria from the raw meat were transferred to the vegetables he planned to serve.

To prevent cross-contamination, it is crucial to use separate knives for different food items or thoroughly clean utensils between uses. By following this practice, we can ensure the safety of the food we prepare and prevent foodborne illnesses.
