Excessive moisture pickup can result in product spoilage and spoilage by: Microorganisms — microorganisms need water to dissolve the food they use. Water allows the food to get into bacterial, yeast and mold cells where it is used for energy and growth.

What are the causes of food spoilage and deterioration?
