Explain the term cross contamination - Junior Cycle Home Economics - Question 5 - 2007

Cross contamination refers to the transfer of bacteria or other harmful substances from one food item or surface to another, which can significantly increase the risk of food poisoning. This often occurs when raw foods, particularly meats, come into contact with cooked foods or food surfaces that are not properly sanitized.

For example, if a cutting board used for raw chicken is not cleaned before being used to prepare vegetables, bacteria from the chicken can contaminate the vegetables, posing a health risk to consumers. It is essential to prevent cross contamination in food preparation areas to ensure food safety.
