This is why food handlers have a legal responsibility to ensure that the food they prepare is free from these contaminants and safe for the consumer.

What are the 3 types of contamination that can affect food?

There are three different types of food contamination – chemical, physical and biological.

What two things does bacteria need to multiply?

Conditions needed for bacterial growth

Moisture – Bacteria need moisture in order to grow.
Food – Food provides energy and nutrients for bacteria to grow.
Time – If provided with the optimum conditions for growth, bacteria can multiply to millions over a small period of time via binary fission .

What are the 4 main growth requirements for bacteria?

What bacteria need to grow and multiply

What are the six 6 conditions in which bacteria can sustain growth?

FAT TOM is a mnemonic device used in the food service industry to describe the six favorable conditions required for the growth of foodborne pathogens. It is an acronym for food, acidity, time, temperature, oxygen and moisture.

What is the danger zone for bacteria?

Bacteria are all around us, including those that can cause food poisoning. Food poisoning bacteria grow best at temperatures between 5°C and 60°C. This is called the Temperature Danger Zone. Keeping potentially hazardous foods cold (below 5°C) or hot (above 60°C) stops the bacteria from growing.

What temperature will kill bacteria?

Bacteria multiply rapidly between 40 and 140 degrees. Bacteria will not multiply but may start to die between 140 and 165 degrees. Bacteria will die at temperatures above 212 degrees. 2.3: How to Take Food Temperatures Know how to get an accurate reading with your thermometer!

Do Germs burn off in the oven?

The problem isn’t with the baking process, because most viruses and bacteria are killed in a hot oven. Gerba’s work has shown that even after 72 hours, 700 viral particles of the cold virus can linger, enough to potentially sicken seven people.

What bacteria can survive boiling water?

Clostridium bacteria can survive in boiling water even at 100 degrees Celsius, which is its boiling point for several minutes. This is because its spores can withstand temperatures of 100 degrees Celsius. However, all waterborne intestinal pathogens are killed above 60 degrees Celsius.

How long do you need to boil water to kill germs?

Boiling is sufficient to kill pathogenic bacteria, viruses and protozoa (WHO, 2015). If water is cloudy, let it settle and filter it through a clean cloth, paperboiling water towel, or coffee filter. Bring water to a rolling boil for at least one minute.

How fast does boiling water kill bacteria?

Does simmering kill bacteria?

The World Health Organization (WHO) notes that bacteria are rapidly killed at temperatures above 149°F (65°C). This temperature is below that of boiling water or even a simmer.

Can boiled water go bad?

Alberta Health Services agrees with the CDC that properly boiled and stored water remains safe to drink for 6 months, as long as the containers are well-sealed. The overall consensus seems that boiling the water sanitizes it, and then storing it in a well-sealed, sanitized container keeps it that way for months.

Does boiling tap water remove chlorine?

Does Boiling Water Remove Chlorine? Yes, boiling water for 15 minutes is one way to release all the chlorine from tap water. At room temperature, chlorine gas weighs less than air and will naturally evaporate off without boiling. But heating up the water to a boil will speed up the chlorine removal process.

Does Brita filter out chlorine?
