Level 3 Food Safety Certificate Contamination and Allergen Control Questions and Answers — Questions and Answers
Question 1: A customer informs their server they have a severe sesame allergy. The dish they want does not list sesame as an ingredient, but the kitchen uses sesame oil and tahini frequently. What is the most appropriate action for the supervisor to take to comply with UK food safety law?
- Instruct the chef to use a separate, clean chopping board and utensils to prepare the meal.
- Advise the customer that due to the high risk of cross-contamination, the business cannot safely guarantee an allergen-free dish. (Correct answer)
- Check the supplier's specification sheet for the dish's ingredients to confirm it is sesame-free.
- Reassure the customer that as long as sesame isn't a direct ingredient, the dish will be safe for them.
Correct answer: Advise the customer that due to the high risk of cross-contamination, the business cannot safely guarantee an allergen-free dish.
Under UK food law, businesses must provide accurate allergen information. When a severe allergy is declared and a high risk of cross-contamination exists that cannot be reliably controlled, the safest and most legally compliant action is to inform the customer that an allergen-free dish cannot be guaranteed. This prioritises customer safety above making a sale.
Question 2: Which of the following represents the most effective and comprehensive approach a supervisor should implement to control the risk of physical contamination from glass?
- Training all staff to immediately report any glass breakages to their supervisor.
- Banning all glass items from food production and storage areas without exception.
- Implementing a documented glass and brittle plastics policy, including a register of items, regular checks, and clear breakage procedures. (Correct answer)
- Switching from glass food storage containers to food-grade plastic alternatives.
Correct answer: Implementing a documented glass and brittle plastics policy, including a register of items, regular checks, and clear breakage procedures.
A formal, documented policy is the most robust management approach. It provides a systematic framework for identifying all glass/brittle plastic items, regularly checking their integrity, and having a clear, pre-planned procedure to follow in case of a breakage to control contamination. This is more comprehensive than any single preventative action.
Question 3: A supervisor observes a new employee about to use a concentrated, non-food-safe degreaser from an unlabelled spray bottle to clean a food preparation surface. What is the primary hazard and the supervisor's most important immediate action?
- Physical contamination hazard; immediately check the surface for any chemical residue.
- Microbiological hazard; immediately tell the employee to use a BS EN 1276 certified sanitiser instead.
- Allergen hazard; immediately ensure the employee washes their hands thoroughly.
- Chemical contamination hazard; immediately stop the activity and secure the chemical and unlabelled bottle. (Correct answer)
Correct answer: Chemical contamination hazard; immediately stop the activity and secure the chemical and unlabelled bottle.
The primary hazard is chemical contamination, which could lead to poisoning if the non-food-safe substance comes into contact with food. Under COSHH Regulations 2002, the supervisor's first priority is to prevent harm by stopping the unsafe act and controlling the hazardous substance. Subsequent actions would involve dealing with any affected food and retraining the employee.
Question 4: *Campylobacter* is the most common cause of bacterial food poisoning in the UK and is strongly associated with raw poultry. Which of the following is the most critical control for a supervisor to enforce to prevent its spread via cross-contamination?
- Strict separation of raw poultry and ready-to-eat (RTE) foods, using dedicated equipment and thorough hand washing. (Correct answer)
- Ensuring all poultry is cooked to a core temperature of 75°C.
- Storing all raw poultry below 5°C in a designated refrigerator.
- Washing all raw chicken thoroughly under cold running water before cooking.
Correct answer: Strict separation of raw poultry and ready-to-eat (RTE) foods, using dedicated equipment and thorough hand washing.
While cooking kills the bacteria in the chicken itself, the question asks about preventing cross-contamination. The Food Standards Agency (FSA) guidance strongly emphasises that the most critical control is preventing the bacteria from spreading from raw poultry to other surfaces and ready-to-eat foods. This is achieved through strict separation, using colour-coded equipment (e.g., red boards for raw meat), and rigorous hand hygiene. Washing raw chicken is discouraged as it splashes bacteria.
Question 5: A coffee shop supervisor oversees the packaging of sandwiches made on-site, which are then placed in a chilled display for customers to choose from. Under the UK legislation commonly known as 'Natasha's Law', what information is legally required on the label of each sandwich?
- A statement advising customers with allergies to speak to a member of staff.
- The name of the food and a full ingredients list, with any of the 14 major allergens emphasised. (Correct answer)
- A list of only the 14 major allergens that are present in the sandwich.
- A 'may contain' warning for any allergens handled in the kitchen environment.
Correct answer: The name of the food and a full ingredients list, with any of the 14 major allergens emphasised.
This type of food is classified as 'prepacked for direct sale' (PPDS). The UK Food Information (Amendment) (England) Regulations 2019, or 'Natasha's Law', mandates that all PPDS food must have a label showing the name of the food and a full ingredients list. Within that list, any of the 14 statutory allergens must be clearly emphasised (e.g., in bold).
Question 6: A food business has excellent prerequisite programmes (PRPs) in place, such as pest control, a cleaning schedule, and staff hygiene policies. What is the primary role of these PRPs in controlling contamination within a food safety management system?
- They identify the specific Critical Control Points (CCPs) for the food preparation process.
- They are the documented corrective actions to be taken if a critical limit is breached.
- They provide the foundational operating and environmental conditions to prevent general hazards from occurring. (Correct answer)
- They are a complete replacement for a HACCP plan in all food businesses.
Correct answer: They provide the foundational operating and environmental conditions to prevent general hazards from occurring.
Prerequisite Programmes (PRPs) are the foundation upon which an effective HACCP system is built. They control the general food safety environment and prevent many common hazards (microbiological, physical, and chemical) from arising in the first place, allowing the HACCP plan to focus on the significant hazards specific to the process steps.
A customer informs their server they have a severe sesame allergy.
The dish they want does not list sesame as an ingredient, but the kitchen uses sesame oil and tahini frequently.
