Lesson 2: Core Concepts: food poisoning & food-borne illness

Duration: 50 minutes

Review Previous Lesson

Quick recap: write 3 key points from Lesson 1 on food poisoning & food-borne illness. Check them against the notes below.

Main Content (35 minutes)

Key Fact: Food poisoning is illness caused by eating food contaminated with harmful bacteria, viruses, or toxins.
Key Fact: The main food poisoning bacteria include: Salmonella, E. coli (especially O157), Campylobacter, Staphylococcus aureus, and Clostridium perfringens.
Key Fact: Salmonella is commonly found in raw poultry and eggs; symptoms include diarrhoea, vomiting, fever, and abdominal cramps.
Key Fact: E. coli O157 is found in undercooked minced beef and unpasteurised milk; it can cause severe kidney damage (haemolytic uraemic syndrome).
Key Fact: Campylobacter is the most common cause of bacterial food poisoning in the UK, often from undercooked poultry.
Key Fact: Staphylococcus aureus produces toxins in food; it is carried on skin and in nasal passages and transfers to food through poor hand hygiene.

Exam-Style Question

Attempt a past-paper style question on food poisoning & food-borne illness from the exam board past paper finder (see Resources), then mark it against the scheme.

Exam Tips: Learn the specific sources, symptoms, and prevention methods for each key bacterium — examiners often ask you to name a bacterium linked to a specific food. | Always distinguish between infection and intoxication when explaining how food poisoning occurs. | When discussing prevention, use the '4 Cs': Cross-contamination, Cleaning, Chilling, and Cooking. | Use precise names: 'Campylobacter' not 'campylobacter bacteria', 'E. coli O157' not just 'E. coli'.
Common Errors: ✗ All food poisoning is caused by bacteria. ✓ Food poisoning can also be caused by viruses (e.g. norovirus), chemical contaminants, or naturally occurring toxins in some plants and fish. ✗ Cooking food always makes it safe to eat. ✓ Cooking kills most bacteria, but if bacteria have already produced toxins in the food (e.g. Staphylococcus aureus), those toxins may not be destroyed by cooking. ✗ E. coli is always harmful. ✓ Most strains of E. coli are harmless and live naturally in the human gut. E. coli O157 is the dangerous strain that produces Shiga toxins. ✗ Food poisoning only happens in restaurants. ✓ Many food poisoning cases are caused by poor food hygiene in the home, such as cross-co
Stretch & Challenge (Grade 8-9):
  • Synoptic links: explain how food poisoning & food-borne illness connects to another Food Preparation and Nutrition topic you have studied
  • Real-world: research one real-world use or example of food poisoning & food-borne illness
  • Critical: "What are the limitations of the models used in food poisoning & food-borne illness?"
