  1. Food Safety Hazards PAPER-2-UNIT-1A

  2. Food safety hazards are found throughout the food supply chain and can be described as: ‘biological, physical or chemical agents in food that are reasonably likely to cause illness or injury in the absence of their control.’ PAPER-2-UNIT-1A

  3. There are three main types of food safety hazards: 1. Biological Hazards Caused by bacteria, viruses or parasites that are present in air, food, water, soil, animals and humans. Food infections and food intoxications can cause severe vomiting, diarrhoea, nausea, abdominal pain and fever to one or lots of people, they can even result in death in some serious cases. Biological hazards receive the most attention in HACCP systems due to presenting the greatest risk of harm and the highest frequency of occurrence. PAPER-2-UNIT-1A

  4. Microorganisms of concern include: Salmonella species, Campylobacter, Escherichia coli, Hepatitis A Staphylococcus aureus,   and Rotovirus. Shigella,  Clostridium perfringens, Clostridium botulinum, Listeria monocytogenes,  PAPER-2-UNIT-1A

  5. .2.PhysicalHazards Foreign bodies in food are usually due to accidental contamination and / or poor handling practices. Physical hazards are most recognized by consumers as they usually find this food safety hazard. PAPER-2-UNIT-1A

  6. Examples of physical hazards include: Metal, dirt, wire, glass, jewellery, plastic, wood, hair, paper insects, fingernails, and personal items, cardboard. stones, soil, bone, nuts / bolts, PAPER-2-UNIT-1A

  7. 3. ChemicalHazards  Can include: CLEANING CHEMICAL RESIDUES: Chemicals used for cleaning and sanitizing food contact surfaces FACTORY CONTAMINANTS: Pest control chemicals, lubricants, coatings, paints, refrigerants and water treatment chemicals AGRICULTURAL RESIDUES: Pesticides, fertilizers, fungicides, antibiotics and growth hormones PAPER-2-UNIT-1A

  8. FOOD ALLERGENS: Eggs, fish, milk, peanuts, sesame seeds, soy, sulphites, tree nuts and wheat NATURALLY OCCURRING HARMFUL CHEMICALS: Mycotoxins, scombrotoxin (histamine), mushroom toxins and shellfish toxins INDUSTRIAL HEAVY METALS: Lead, zinc, cadmium, arsenic and mercury. PAPER-2-UNIT-1A

  9. Food safety hazards are best controlled through the use of HACCP systems. All significant food safety hazards at each stage of production must be identified in a HACCP plan. Once you know where food safety hazards occur, it is possible to implement control measures to prevent, reduce or eliminate food safety hazards to an acceptable level. PAPER-2-UNIT-1A
