Study Notes
Salmonella
- Found in human and animal intestines, present throughout the food chain
- Incubation period: 12-36 hours
- Control measures: proper cooking, temperature control, hygiene practices, avoiding cross-contamination, pest control, staff training, and using quality-assured eggs
Staphylococcus Aureus
- Carried by humans (nose, hair, mouth, etc.) and infects raw milk or processed foods handled by many people
- Incubation period: 1-6 hours
- Control measures: temperature control, good personal hygiene, excluding infected individuals from food handling, using pasteurized milk, and staff training
Clostridium Perfringens
- Originates from human intestines, spread by insects and flies to raw meat and cooked dishes like stews
- Incubation period: 8-24 hours
- Control measures: cooking in small batches, washing vegetables thoroughly, maintaining strict hygiene and temperature control, staff training, and designated food zones
Clostridium Botulinum
- Found in soil and intestines of animals/humans, can grow in canned foods under improper conditions
- Incubation period: 12 hours to several days
- Control measures: proper heat treatment of canned foods, strict controls on fish smoking and handling, discarding defective cans, maintaining acidic environments, and staff training
Bacillus Cereus
- Originates from soil and dust, contaminates cereals, spices, dairy products, and starchy foods
- Incubation period: 0-24 hours
- Control measures: thorough cooking, proper temperature control, reheating only once, and staff training
E.Coli
- Found in human and animal intestines, present in raw meat (especially minced), untreated water, and unpasteurized milk
- Incubation period: 12-72 hours
- Control measures: personal hygiene, milk pasteurization, proper cooking of meat, and staff training
Campylobacter Jejuni
- Originates from animal intestines, transmitted through raw milk, untreated water, cross-contamination with poultry, and can cause relapses
- Incubation period: 2-7 days
- Control measures: milk pasteurization, thorough cooking, washing vegetables, proper reheating, strict temperature control, staff training, and designated food zones
Listeria
- Found in contaminated utensils, soil, dust, raw milk products, vegetables, and some cheeses
- Incubation period: 1-72 days (long incubation period)
- Control measures: milk pasteurization, thorough cooking, meticulous vegetable washing, proper reheating, strict temperature control, staff training, and designated food zones
