Common Symptoms of Food Poisoning
- Stomach pains
- Vomiting
- Diarrhoea
- Nausea
- Dehydration
- Fever
- Death
Causes of food poisoning
- Bacteria
- Viruses
- Poisonous Plants and Fish
- Chemicals
- Metals
Viruses
Only grow in a living cell. Found commonly in shellfish, due to their culture in sewage water. They are very small and can only be seen under an electron microscope. They remain infectious in chilled or frozen foods.
Plants
- Toad stools
- Deadly Nightshade
- Red kidney beans
- Rhubarb leaves
- Poisonous fungi
Chemicals
- Herbicides
- Pesticides
- Fungicides
- Cleaning materials
- Food additives
Metals
- Cadmium
- Copper
- Zinc
- Lead
- Tin and iron
- Mercury
Food Intolerance and Allergy:
- Unusual sensitivity to food which is harmless to most people.
- They can kill
- Cause a reaction called anaphylaxis
- Symptoms may include swelling of throat and mouth making breathing difficult
- Common foods are peanuts, shellfish and sesame seeds.
- A minute amount can trigger a reaction
BACTERIA
- Microscopic (1 -3 microns )
- Single celled
- Found everywhere
- Mostly harmless some essential
- Some cause illness called pathogens
- Poor hygiene may lead to large numbers in food
Bacteriology
Bacteria are essential to life, often referred to as germs they are found everywhere, including on and in man. However, two types create problems in the food industry.
- Spoilage bacteria
- Pathogenic bacteria
Factors influencing bacterial growth
- Nutrients
- Temperature
- Moisture
- Time
- Oxygen
- pH
High Risk Foods:
Foods involved in Bacterial Food Poisoning:
Foods which are moist and have a high protein content. They are also intended for consumption without further cooking
Examples of High-Risk Foods
- Cooked meat and poultry
- Meat products e.g. gravy and stock
- Dairy products
- Egg dishes
- Fish and shellfish
- Cooked rice
Source and Prevention:
- Hands
- Regular washing with bacterial soap
- Body
- Chopping Boards
- Separate boards, colour coded and easy to clean
- Storage
- Separate raw foods from cooked
- Airborne
- Utensils
- Preparation Surfaces
- Suitable material and use of sanitizer
- Pests
- Refuse Area
- Cleaned regularly and washing of hands after use
- Chefs Cloth
How to Establish A Supplier Safety Assurance?
- Supplier auditing
- Recognized certificates of conformity
