IMMUNOLOGY

Detailed explanation-1: -Bacteria can live in hotter and colder temperatures than humans, but they do best in a warm, moist, protein-rich environment that is pH neutral or slightly acidic.

Detailed explanation-2: -These are: temperatures, moisture, oxygen, and a particular pH. Many bacteria prefer warm environments, but there are some that thrive in low or high temperatures.

Detailed explanation-3: -Food poisoning bacteria must have moisture to stay alive. Bacteria will not multiply in dried foods such as dried pasta, rice, biscuits. As soon as water/liquid is added however, bacterial multiplication starts again.

Detailed explanation-4: -Water is essential for all living organisms. It functions as a solvent, a temperature buffer and a metabolite in living cells. Unlike animals, plants and microorganisms rely largely on their immediate surroundings for water.

Detailed explanation-5: -The Food Standards Agency (FSA) sets the temperature danger zone of food to be between 8°C and 60°C. This means that food is safest when it is either frozen or chilled below 8°C or heated beyond 60°C. The optimum temperature for bacteria growth is 37°C, which is the same temperature as the human body.

Detailed explanation-6: -Bacteria grow most rapidly in the range of temperatures between 40 °F and 140 °F, doubling in number in as little as 20 minutes. This range of temperatures is often called the “Danger Zone.” To learn more about the “Danger Zone” visit the Food Safety and Inspection Service fact sheet titled Danger Zone.

Detailed explanation-7: -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 . More items
