How quickly can bacteria multiply in ideal conditions?

In ideal conditions a bacterium divides in two roughly every ten to twenty minutes, so a small number can become millions within a few hours.

What is a high-risk food?

A high-risk food is one that is ready to eat, moist and rich in protein, and that needs refrigeration because it will receive no further cooking to destroy bacteria.

Which foods are most associated with salmonella, and what is the usual onset time?

Salmonella is most associated with poultry, raw eggs, raw meat and unpasteurised milk, and symptoms usually begin between twelve and seventy-two hours after eating.

Questions from this subtopic

Each one with the model answer underneath.

1
Which four conditions do bacteria need in order to multiply?
Model answer
Bacteria need food, moisture, warmth and time in order to multiply, and most food poisoning bacteria also prefer a near-neutral acidity.
2
How quickly can bacteria multiply in ideal conditions?
Model answer
In ideal conditions a bacterium divides in two roughly every ten to twenty minutes, so a small number can become millions within a few hours.
3
What is a high-risk food?
Model answer
A high-risk food is one that is ready to eat, moist and rich in protein, and that needs refrigeration because it will receive no further cooking to destroy bacteria.
4
Name five high-risk foods.
Model answer
Cooked meat and poultry, cooked rice and pasta, dairy products, shellfish, and gravies, stocks and sauces are all high-risk foods.
5
Why do bacterial spores matter in food safety?
Model answer
Some bacteria form spores that survive normal cooking temperatures, so if food is then left in the danger zone the spores germinate and the bacteria multiply again.
6
Which foods are most associated with salmonella, and what is the usual onset time?
Model answer
Salmonella is most associated with poultry, raw eggs, raw meat and unpasteurised milk, and symptoms usually begin between twelve and seventy-two hours after eating.
