Direct answer
The main ways to prevent cross-contamination are to store food in the correct order, separate raw and ready-to-eat foods, use dedicated or properly cleaned and sanitized equipment, wash hands at the right times, and protect food from allergen cross-contact.
If ready-to-eat food has been contaminated by raw meat juice, dirty equipment, bare hands, or an undeclared allergen, the manager action is usually to stop service and correct or discard the affected food.
High-value prevention steps
Most exam scenarios are not exotic. They are common kitchen mistakes: raw chicken stored above lettuce, a knife reused between raw and cooked food, gloves not changed, or cooked meat placed on a raw-meat tray.
- Store ready-to-eat food above raw animal foods.
- Use separate cutting boards or clean and sanitize between tasks.
- Wash hands after handling raw food, trash, phones, face, hair, or dirty equipment.
- Use new gloves when the task changes or gloves become contaminated.
- Keep allergen orders, utensils, and surfaces controlled.
Exam trap
If food reached the correct cooking temperature but was contaminated afterward, the temperature is no longer the main issue. The correct answer is about preventing contamination or discarding unsafe food.
