FOOD The nutrients available in food often determines whether microorganisms will grow. While some microorganisms have simple nutrient requirements, some pathogens require a complex diet, including proteins. Moist protein-rich foods, such as meat, milk, eggs and fish, are potentially hazardous. They are most likely to cause foodborne illness because they are a food source for pathogenic bacteria and can support growth of these bacteria. 6

ACIDITY The degree of acidity or alkalinity (base) of a substance is measured by its p. H is measured on a scale from 0 to 14. 0. An environment with a p. H of 7. 0 is exactly neutral. Foods with a p. H below 7. 0 are acidic; a p. H above 7. 0 is alkaline. The lower the p. H, the higher the acidity; the higher the p. H, the lower the acidity. Bacteria grow best in an environment that is neutral or slightly acidic. Most bacterial growth is inhibited in very acidic conditions. That is why acidic foods, like vinegar and fresh fruits (especially citrus), seldom provide a favorable climate for pathogenic bacteria. Most bacteria will not grow at p. H levels below 4. 6 because the environment is too acidic. Microorganisms thrive in a p. H range between 6. 6 and 7. 5. 7

T=TEMPERATURE Microorganisms grow and reproduce quickly between the temperatures of 41° and 135°F (5° to 57° c). During the two-hour period in the TEMPERATURE DANGER ZONE (TDZ) , minimal growth and reproduction will occur especially if there is a neutral environment and protein source. One important rule of food safety is to limit time that foods are in the TDZ. Keep foods refrigerated (below 41°F) until it is time to cook. Cool left over foods quickly. 10

TIME Also known as the four-hour rule Pathogenic microorganisms reproduce by cell division. One becomes two. Two become four. Small numbers of pathogens may be present in foods, but they pose a very low risk to consumers, especially if the food is cooked. However, when low acid and high protein available foods (neutral or alkaline p. H) are abused by placing them in the TEMPERATURE DANGER ZONE (TDZ) (41° to 135°F) for more than four hours, pathogens will have multiplied to such high levels in the food, eating this food will make people ill rapidly. Restricting the time low acid and high protein foods stay in the TDZ to two hours or less prevents growth of large numbers of pathogens. 11

OXYGEN Microorganisms that need oxygen (air) to grow are called aerobic. When foods such as meat, spaghetti sauce or vegetables are canned, oxygen is excluded from the environment. Therefore, growth of aerobic organisms is controlled and the food is preserved. Such foods are shelf stable and do not require refrigeration until they are opened. Some microorganisms will grow only in anaerobic conditions (in the absence of oxygen). Botulism, a rare type of foodborne illness, is caused by a specific type of bacteria called clostridium botulism that grows only in anaerobic conditions. Improperly preserved home canned foods are a typical source of botulism. Home canned items can not be used in foodservices. 14

Moisture content Microorganisms must have an abundant supply of Microorganisms water to grow. Food perishability is related to moisture content Food perishability and water activity level. Moisture content is the amount of water in food expressed as a percentage. Water activity ( aw ) is ) the amount of water available for use and is measured on a scale of 0 to 1. 0. 16

MOISTURE Foods preserved with salt or sugar, such as beef jerky or jams and jellies have a lower aw because salt and sugar deprive microorganisms of water and inhibit their reproduction. These products are shelf-stable (i. e. they do not need refrigeration, unless opened). Pathogenic bacteria have difficulty growing in foods such as dry noodles, flours, candies and crackers, where aw is below 0. 85. 18
