What is one example of cross-contamination?

Cross-contamination refers to the transfer of harmful bacteria or allergens from one food item to another, particularly when handling raw foods. Using the same cutting board for vegetables and raw chicken is a prime example of cross-contamination because raw chicken can harbor pathogens like Salmonella and Campylobacter. If the same cutting board is used for vegetables without proper cleaning in between, these harmful bacteria can transfer from the chicken to the vegetables, increasing the risk of foodborne illness when the vegetables are consumed.

In contrast, using a clean plate for raw meats is a safe practice that prevents cross-contamination. Washing hands before food prep is a critical hygiene practice that helps prevent the spread of contaminants, safeguarding food safety. Storing food in a clean refrigerator also ensures that food is kept safe from contamination, as it provides an environment that prevents cross-contamination among different food items.
