Level 3 Food Safety Certificate Food Contamination and Allergen Management — Questions and Answers
Question 1: What is 'cross-contamination' in food safety?
- The transfer of harmful microorganisms or allergens from one food or surface to another (Correct answer)
- Only the transfer of allergens
- The contamination of food by pests only
- Physical contamination by foreign objects
Correct answer: The transfer of harmful microorganisms or allergens from one food or surface to another
Cross-contamination is the transfer of harmful microorganisms, allergens, or other contaminants from contaminated food, surfaces, equipment, or people to previously safe food.
Question 2: Which of the following bacteria is most commonly associated with undercooked poultry and is a leading cause of foodborne illness in the UK?
- Campylobacter jejuni (Correct answer)
- Salmonella typhi
- Listeria monocytogenes
- Escherichia coli O157
Correct answer: Campylobacter jejuni
Campylobacter is the most commonly reported cause of food poisoning in the UK and is most frequently associated with undercooked poultry and cross-contamination from raw chicken.
Question 3: What temperature must poultry reach at its thickest point to ensure it is safe to eat?
- 75°C (Correct answer)
- 65°C
- 80°C
- 70°C
Correct answer: 75°C
Poultry must reach a core temperature of 75°C (or 70°C for 2 minutes) to kill Campylobacter and Salmonella. Some UK guidance uses 75°C as the safe minimum core temperature.
Question 4: What is 'anaphylaxis' and why is allergen management critical in catering?
- A severe, life-threatening allergic reaction that can be triggered by even a trace amount of a food allergen (Correct answer)
- A mild allergic reaction treated with antihistamines
- A bacterial infection from food
- A type of food intolerance without immune system involvement
Correct answer: A severe, life-threatening allergic reaction that can be triggered by even a trace amount of a food allergen
Anaphylaxis is a severe, systemic allergic reaction that can cause airways to close and lead to death within minutes — even trace amounts of an allergen can trigger it in sensitised individuals.
Question 5: What are the 14 major allergens that must be declared under UK food information law?
- Celery, cereals containing gluten, crustaceans, eggs, fish, lupin, milk, molluscs, mustard, peanuts, sesame, soya, sulphites/sulphur dioxide, tree nuts (Correct answer)
- Milk, eggs, peanuts, tree nuts, fish, crustaceans, gluten (7 only)
- Only peanuts, tree nuts, and shellfish
- Peanuts, milk, eggs, soya, wheat, fish, shellfish (7 only)
Correct answer: Celery, cereals containing gluten, crustaceans, eggs, fish, lupin, milk, molluscs, mustard, peanuts, sesame, soya, sulphites/sulphur dioxide, tree nuts
UK law (Natasha's Law and the FIR 2014) requires declaration of 14 allergens: celery, cereals containing gluten, crustaceans, eggs, fish, lupin, milk, molluscs, mustard, peanuts, sesame, soya, sulphur dioxide/sulphites, and tree nuts.
Question 6: What is 'Natasha's Law' and when did it come into effect?
- A 2021 UK law requiring full ingredient and allergen labelling on all pre-packaged for direct sale (PPDS) foods (Correct answer)
- A 2019 law banning nut products in schools
- A law requiring allergen menus in restaurants
- A law requiring staff to hold allergen qualifications
Correct answer: A 2021 UK law requiring full ingredient and allergen labelling on all pre-packaged for direct sale (PPDS) foods
Natasha's Law (October 2021) requires full ingredient and allergen labelling on all PPDS food — food made and packaged on the same premises where it is sold, such as sandwiches and wraps.
