HUMAN NUTRITION

Detailed explanation-1: -The majority require relative humidity (RH) of 60 percent or more, though some can survive and multiply in >20 percent RH. Thus, decreasing temperature and moisture (relative humidity), creates a less hospitable environment for microorganisms to grow.

Detailed explanation-2: -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-3: -Moisture is the final component necessary for bacterial growth. The higher the water content of foods, the greater their chance of bacterial contamination. Due to their high water content and often low-acidity, fresh fruits and vegetables are at a high risk for bacterial contamination.

Detailed explanation-4: -A thermophile is an organism-a type of extremophile-that thrives at relatively high temperatures, between 41 and 122 °C (106 and 252 °F). Many thermophiles are archaea, though they can be bacteria or fungi. Thermophilic eubacteria are suggested to have been among the earliest bacteria.
