Bacteria are a form of tiny germ that thrive is certain environments bacteria can reproduce outside or inside the body given the right conditions and in. Water -- bacteria need water to dissolve the food they use for energy and growth water allows the food to get into the cells, is used for the many chemical reactions necessary for life and growth, and allows waste products to escape. Most foods have a water activity above 095 and that will provide sufficient moisture to support the growth of bacteria, yeasts, and mold the amount of available moisture can be reduced to a point that will inhibit the growth of microorganisms.
