How many types of bacterial food poisoning are there?
There are two types
What are the two types of bacterial food poisoning?
Infectious food poisoning and toxic food poisoning
What is infectious food poisoning?
An illness caused by eating food containing pathogenic bacteria that produce endotoxins
What is toxic food poisoning?
An illness caused by eating food containing pathogenic bacteria that produces exotoxins
When are endotoxins released by a bacteria?
They are released when the bacterial cell dies
When are exotoxins produced by a bacteria?
Before or after the food is eaten
How are endotoxins destroyed?
They are destroyed easily by normal cooking temperatures
How are exotoxins destroyed?
They are difficult to destroy and can be destroyed by 30 minutes of boiling
What is the incubation period of infectious food poisoning?
It has a long incubation period of over 12 hours
What is the incubation period of toxic food poisoning?
It has a short incubation period of around 2 hours
What are two examples of infectious food poisoning causing bacteria?
Salmonella
E.coli
