types of pathogenic microorganisms in food
Bacteria, yeasts, and mold are microorganisms associated with foods. The individual microorganism cannot be seen without the aid of a microscope. The size of these microorganisms are measured in microns (1 micron is 1/1000 of a millimeter or U25,40A of an inch).hen enough salt or sugar is added to a food, the water activity will be lowered to a level that will prevent microorganisms from growing. 1  In general, bacterial glowth is inhibited by the addition of 5-15% salt. 2  To inhibit mold growth, 65-70% sugar must be added.
