The mesophiles group that well at 30-37 degrees Celsius. And bacteria is the main cause of milk left at room temperature the location references and lose. As well as the bacteria that cause the disease. The diseases of the digestive system. Microorganisms the group that mainly found from the counting the total microbial sources come from the environment, such as within the housing. On the floor, stables, the equipment is used to milk the personnel involved. The containers of raw milk.Coliform bacteria, coliform group Found in the intestines of humans and animals in the feces. In dairy cows with mastitis. Contaminated from the container, milking, personnel, and in the stables, which clean not thoroughly. From the container of milk bacteria groups are an indicator to the hygienic production if detected microorganisms this group more than 100 cells. On 1 ml milk that healthy bad traits of farm milking cows, and may come from a inflammatory breast diseases. The bacteria in milk pasteurization. Show errors in the production process. And may the heat for disinfection is not enough were contaminated while packing group thermodurics bacteria. A high temperature resistant microorganisms and not be sterilized with the natural convection สเจ. So if this group of bacteria in raw milk. To have left in milk's homemade luck more. But the infection will not grow. The source is used milk processing equipment and piping system in dairy processing plants, a group of thermophiles. Bacteria can grow at high temperature 55 degrees Celsius. Temperature and pasteurization. But if the temperature is too high, 70 degrees Celsius. This group of bacteria will not thrive. The source is from soil and forage, and found in the machinery, equipment, food processing, a group of psychrotrophic. As the bacteria that well at low temperatures, the source of the contamination. Is from the water used in the clean water tank farm, raw milk, milk truck, which has low temperature 2-7 degrees Celsius.
