Food Spoilage Food is considered contaminated when unwanted microorganisms are present. Most of the time the  contamination is natural, but sometimes it is artificial.  Natural contamination  occurs when  microorganisms attach themselves to foods while the foods are in their growing stages. For instance,  fruits are often contaminated with yeasts because yeasts ferment the carbohydrates in fruits.  Artificial contamination  occurs when food is handled or processed, such as when fecal bacteria  enter food through improper handling procedures.  Food spoilage  is a disagreeable change or departure from the food's normal state. Such a change  can be detected with the senses of smell, taste, touch, or vision. Changes occurring in food depend  upon the composition of food and the microorganisms present in it and result from chemical  reactions relating to the metabolic activities of microorganisms as they grow in the food.
