How can cross-contamination occur in food handling?

Cross-contamination can occur during food handling when there is a transfer of harmful microorganisms from one surface or food item to another. When someone adjusts their hair while wearing a hairnet and then continues to prepare food without changing their gloves or washing their hands, they can inadvertently transfer pathogens from their hair to the food. This behavior does not maintain proper hygiene standards and increases the risk of foodborne illness.

Using hand sanitizer before preparing food is a proactive step to ensure cleanliness, while separating raw and cooked foods and wearing gloves when handling food are practices put in place to prevent cross-contamination. These practices help maintain food safety by reducing the chances of harmful bacteria spreading during food preparation. Proper hygiene and food handling procedures are crucial in preventing cross-contamination and ensuring food safety.
