Study Notes
Hygiene Measures
- Food premises, equipment, and facilities should be designed to minimize contamination
- Design should allow for cleaning, disinfection, and minimize airborne contamination
- Surfaces in contact with food should be non-toxic, durable, and easy to clean
- Adequate facilities for temperature, humidity, and other controls should be available
- Protection from pests is crucial
Food Hazards
- Food hazards are contaminants that can cause harm to consumers
- Four types of food hazards: biological, chemical, physical, and allergenic
Biological Hazards
- Microorganisms contaminate food, and poor practices allow pathogens to grow
- Contamination can occur during storage, preparation, processing, packing, and distribution
- Cross-contamination, poor hygiene, and expired ingredients contribute to biological hazards
- The risk depends on the type of food: high-risk foods like dairy, eggs, meat, fish, and poultry are more susceptible
- Examples of biological hazards: bacteria, fungi, viruses, and parasites
- These microorganisms can cause foodborne illnesses, including food poisoning and intoxication
Chemical Hazards
- Chemical hazards occur when natural or human-made substances contaminate food
- Sources include cross-contamination from chemicals stored in food storage areas and non-food grade chemicals used on food surfaces
- Contamination can also occur during processing, such as acrylamide produced during high-temperature cooking
- Examples of chemical hazards: toxins from animals, plants, and microorganisms, unintentionally added chemicals (cleaning products, pesticides), intentionally added chemicals (flavorings, preservatives) in excess
- Chemical contamination can cause immediate harm or long-term health effects
Physical Hazards
- Physical hazards are foreign materials in food, present during manufacturing or in raw ingredients
- Sources include poor personal hygiene, packaging, poorly maintained premises and equipment, and pests
- Examples of physical hazards: natural hazards (dirt, fruit pips, bones) and unnatural hazards (stones, hair, fingernails, plastic, glass, metal)
- Physical hazards can cause injuries to the mouth, teeth, and gums, and can even lead to choking
- Some physical contaminants are unpleasant to find in food
Allergenic Hazards
- Allergens are proteins found naturally in some foods that can contaminate others
- Cross-contact can lead to allergic reactions in food allergy sufferers
- The risk of anaphylaxis is present in individuals with severe allergies
- 14 recognized allergens include: eggs, mustard, fish, tree nuts, milk, sesame, peanuts, soybeans, celery, cereals (gluten)
