What is cross-contamination?

1. The process of cooking meat thoroughly

2. A method of preserving food

3. The spread of germs from one place to another

4. A cleaning technique

The correct answer is: The spread of germs from one place to another

Cross-contamination is when harmful bacteria or other microorganisms spread from one surface or object to another, potentially causing contamination and illness. This can occur when different types of food come into contact with each other or when surfaces and utensils are used for multiple types of food without proper cleaning. Option A, cooking meat thoroughly, may help prevent cross-contamination by killing harmful bacteria present on the meat, but it is not the definition of cross-contamination. Option B, preserving food, is unrelated to the spread of germs and bacteria. Option D, cleaning technique, is important in preventing cross-contamination, but it is not the definition of the term. Therefore, option C is the most accurate and comprehensive definition of cross-contamination.
