What is the definition of cross contamination?

Cross contamination is primarily understood as the process by which harmful bacteria or other microorganisms are inadvertently transferred from one surface or food item to another, posing a risk for foodborne illness. This includes instances such as transferring bacteria from raw foods to cooked foods or between different surfaces that come into contact with food.

The correct definition aligns closely with the concept of transferring bacteria from one surface to another. This can occur in various situations, such as using the same utensils or surfaces without appropriate cleaning in between, thereby allowing bacteria from raw items to contaminate cooked foods that are ready for consumption. Understanding this concept is crucial in food safety practices, as it plays a significant role in ensuring that food remains safe to eat by preventing the spread of pathogens that can cause illness.

The other choices refer to aspects of food safety but do not define cross contamination specifically or accurately. For example, the idea of a link between safe water and dirty water speaks more to water safety issues rather than food practices. Mixing cooked and raw foods indeed can lead to cross contamination but does not encompass the full definition. Lastly, using the same cutting board can contribute to cross contamination, but simply the act of using a board alone does not define the term comprehensively.
