Study Notes
Food Microbiology Introduction
- Food microbiology studies microorganisms (bacteria, viruses, fungi, protozoa) that affect, contaminate, or spoil food
- It's vital for food safety and quality
Key Areas in Food Microbiology
- Foodborne Illness: Understanding causes, prevention, and control of foodborne illnesses
- Food Preservation: Methods to maintain food safety and quality over time
- Food Spoilage: Investigating microbial processes causing food degradation
Factors Affecting Microbial Growth
- Temperature: Microorganisms thrive within optimal temperature ranges
- pH: Food acidity or alkalinity impacts microbial growth
- Moisture: Microorganisms need a certain water activity level for growth
- Oxygen: Some need oxygen, others don't
- Nutrients: Microorganisms need nutrients for growth and reproduction
Importance of Food Microbiology
- Public Health: Protecting consumers from foodborne diseases
- Food Safety: Guaranteeing food safety for consumption
- Food Quality: Maintaining food's sensory qualities and nutritional value
- Food Industry: Providing scientific knowledge for food processing, packaging, and storage
Common Foodborne Pathogens
- Bacteria: Salmonella, E. coli, Listeria monocytogenes, Staphylococcus aureus
- Viruses: Norovirus, Hepatitis A
- Parasites: Toxoplasma gondii, Trichinella spiralis
Food Intoxication
- Staphylococcus aureus is a common cause of food intoxication
Food Poisoning Symptoms (Examples)
- E. coli: Watery diarrhea (sometimes bloody), low fever, loss of appetite, nausea, vomiting, stomach pains, and cramps, fatigue
- Food poisoning symptoms vary depending on the specific pathogen
Preventing Hepatitis A
- Vaccination
- Wash fruits and vegetables
- Cook food thoroughly
- Cool food promptly
- Clean dishes
- Wash hands
- Use clean drinking water
