HUMAN NUTRITION

Detailed explanation-1: -When you leave foods that are prone to contamination in the danger zone temperature range (40–140°F or 4–60°C), the number of bacteria on them can double in as little as 20 minutes. After 2 hours, the food is likely unsafe to eat.

Detailed explanation-2: -Why it matters: Bacteria are among the fastest reproducing organisms in the world, doubling every 4 to 20 minutes.

Detailed explanation-3: -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.” Never leave food out of refrigeration over 2 hours.

Detailed explanation-4: -Some bacteria multiply or double every fifteen minutes. For example if we take a piece of cooked turkey and leave it sitting out at room temperature (which is about 80oF) and it has one harmful bacterium, this is how the bacterium will grow: Fifteen minutes later, there are 2 bacteria.
