Level 2 Food Hygiene Certificate Cross-Contamination 2

Question 1

What is the main food safety risk associated with using the same knife to cut raw chicken and then slice cooked ham without cleaning it?

Accepted Answer

Harmful bacteria such as Salmonella and Campylobacter from the raw chicken can be transferred to the ready-to-eat ham

Answer

Raw chicken commonly carries Salmonella and Campylobacter bacteria. Using the same knife without thorough cleaning and disinfection transfers these pathogens to the cooked ham, which will not receive further cooking to kill the bacteria. This is a classic example of cross-contamination.

Question 2

What does 'clean as you go' mean in a food preparation environment?

Accepted Answer

Clean and disinfect work surfaces, equipment, and utensils throughout the working day rather than leaving all cleaning until the end

Answer

'Clean as you go' means continuously maintaining cleanliness throughout the working period. This includes wiping down surfaces between tasks, washing utensils after use with different foods, and keeping the work area tidy. It significantly reduces the risk of cross-contamination compared to batch cleaning at the end of the day.

Question 3

Why is it important to keep raw and cooked foods separated during delivery and storage?

Accepted Answer

To prevent bacteria from raw foods contaminating cooked or ready-to-eat foods, which will not undergo further cooking

Answer

Raw foods (especially meat, poultry, and fish) can carry pathogenic bacteria. If these bacteria transfer to cooked or ready-to-eat foods, those foods will not receive further cooking to kill the bacteria, creating a direct food poisoning risk. Separation must be maintained at all stages — delivery, storage, preparation, and display.

Question 4

What is the purpose of food-grade cleaning cloths being colour-coded in food premises?

Accepted Answer

To prevent cross-contamination by using different coloured cloths for different areas and tasks, preventing bacteria transfer between zones

Answer

Colour-coded cleaning cloths work on the same principle as colour-coded chopping boards — they prevent cross-contamination between different areas. For example, one colour might be used for raw food areas, another for ready-to-eat areas, and another for toilets/washrooms. This prevents bacteria being transferred between high-risk and low-risk areas.

Question 5

A food handler is preparing sandwiches (ready-to-eat food). What should they do if they need to handle raw eggs during the task?

Accepted Answer

Wash hands thoroughly, change gloves if worn, and clean/disinfect the preparation area before returning to sandwich preparation

Answer

Raw eggs can carry Salmonella bacteria. When switching between raw and ready-to-eat foods, food handlers must wash their hands thoroughly, change gloves if worn, and clean and disinfect any surfaces or equipment. This breaks the chain of cross-contamination between raw and ready-to-eat items.
