"systematic review of the food safety of unpasteurized milk concluded that science-based data to substantiate claims of health benefits ""are lacking or do not exist"" and the risks associated with disease outbreaks as a result of raw milk consumption are ""considerably higher"". Pasteurization was first used in the United States in the 1890s after the discovery of germ theory to control the hazards of highly contagious bacterial diseases, including bovine tuberculosis and brucellosis, that could be easily transmitted to humans through the drinking of raw milk.

Patients who have had brucellosis should probably be excluded indefinitely from donating blood or organs. Exposure of diagnostic laboratory personnel to ""Brucella"" organisms remains a problem in both endemic settings and when brucellosis is unknowingly imported by a patient.

"pasteurization can include tuberculosis, brucellosis, diphtheria, scarlet fever, and Q-fever; it also kills the harmful bacteria ""Salmonella"", ""Listeria"", ""Yersinia"", ""Campylobacter"", ""Staphylococcus aureus"", and """", among others. Prior to industrialization, dairy cows were kept in urban areas to limit the time between milk production and consumption, hence the risk of disease transmission via raw milk was reduced. As urban densities increased and supply chains lengthened to the distance from country to city, raw milk (often days old) became recognized as a source of disease. For example, between 1912 and 1937, some 65,000 people died of tuberculosis contracted from consuming milk in"

However, the microbiological techniques used until the 1960s did not allow for the actual reduction of bacteria to be enumerated. Demonstration of the extent of inactivation of pathogenic bacteria by milk pasteurization came from a study of surviving bacteria in milk that was heat-treated after being deliberately spiked with high levels of the most heat-resistant strains of the most significant milk-borne pathogens. The mean log reductions and temperatures of inactivation of the major milk-borne pathogens during a 15-second treatment are: The Codex Alimentarius ""Code of Hygienic Practice for Milk"" notes that"

However, the use of more than one antibiotic is needed for several weeks, because the bacteria incubate within cells. Surveillance using serological tests, as well as tests on milk like the milk ring test, can be used for screening and play an important role in campaigns to eliminate the disease. Also, individual animal testing both for trade and for disease-control purposes is practiced. In endemic areas, vaccination is often used to reduce the incidence of infection. An animal vaccine is available that uses modified live bacteria. The World Organisation for Animal"

Pasteurization is widely accepted to improve the safety of milk products by reducing the exposure to pathogens. Opponents of pasteurization argue that unpasteurized milk has benefits associated with superior taste, nutritional qualities and certain health benefits over pasteurized milk. While pasteurization of milk kills off bacterial pathogens, other bacteria species with possible health benefits are also destroyed. Pasteurization of cow's milk destroys any potential pathogens and increases the shelf life. During pasteurization, however, these lactic acid bacteria are mostly destroyed. A 2009"

In 1892, chemist Earnest Lederle experimentally inoculated milk from tuberculosis-diseased cows into guinea pigs, which caused them to develop the disease. In 1910, Lederle, then in the role of Commissioner of Health, introduced mandatory pasteurization of milk in New York City. Developed countries adopted milk pasteurization to prevent such disease and loss of life, and as a result milk is now widely considered one of the safest foods.

Complete inactivation of ""Coxiella burnetii"" (which was thought at the time to cause Q fever by oral ingestion of infected milk) as well as of ""Mycobacterium tuberculosis"" (which causes tuberculosis) were later demonstrated.

Current practices of animal husbandry generally control the pastures and feed of cattle, and the pooling of milk from many producers lowers the risk of tremetol present in dangerous amounts. The poison tremetol is not inactivated by pasteurization. Although extremely rare, milk sickness can occur if a person drinks contaminated milk or eats dairy products gathered from a single cow or from a smaller herd that has fed on the white snakeroot plant. There is no cure, but treatment"
"In addition to careful screening of donors, each batch of milk is tested for bacterial counts before pasteurization. Some milk banks pool milk before testing it, others test each mother's milk as it comes in before it is pooled. Milk banks require freezers and pasteurizers for processing milk. Most milk banks have two freezers, for unprocessed and processed milk. The HMBANA guidelines state that ""all milk should be heat treated for 30 minutes at 62.5 °C. Heat treatment of milk occurs at 62.5°C for 30 minutes (Holder pasteurizing)"" (Arnold, 1997, p. 243). At the end of pasteurization, another sample of"

High-temperature short-time (HTST) pasteurization, such as that used for milk ( for 15 seconds) ensures safety of milk and provides a refrigerated shelf life of approximately two weeks. In ultra-high-temperature (UHT) pasteurization, milk is pasteurized at for 1–2 seconds, which provides the same level of safety, but along with the packaging, extends shelf life to three months under refrigeration. Direct microbiological techniques are the ultimate measurement of pathogen contamination, but these are costly and time-consuming, which means that products have a reduced shelf-life by the time pasteurization is verified.

This move successfully controlled the spread of highly contagious bacterial diseases including ""E. coli"", bovine tuberculosis and brucellosis (all thought to be easily transmitted to humans through the drinking of raw milk). In the early days after the scientific discovery of bacteria, there was no product testing to determine whether a farmer's milk was safe or infected, so all milk was treated as potentially contagious. After the first tests were developed, some farmers took steps to prevent their infected animals from being killed and removed from food production, sometimes even falsifying test results to make their animals appear free"
"soon go to surgery, but even if such people have low hemoglobin, they should be given oral treatment or intravenous iron. Iron is needed for bacterial growth making its bioavailability an important factor in controlling infection. Blood plasma as a result carries iron tightly bound to transferrin, which is taken up by cells by endocytosing transferrin, thus preventing its access to bacteria. Between 15 and 20 percent of the protein content in human milk consists of lactoferrin that binds iron. As a comparison, in cow's milk, this is only 2 percent. As a result, breast fed babies have fewer infections."
"of the unsuitability of microbiological techniques, milk pasteurization efficacy is typically monitored by checking for the presence of alkaline phosphatase, which is denatured by pasteurization. Destruction of alkaline phosphatase ensures the destruction of common milk pathogens. Therefore, the presence of alkaline phosphatase is an ideal indicator of pasteurization efficacy. For liquid eggs, the effectiveness of the heat treatment is measured by the residual activity of α-amylase. During the early 20th century, there was no robust knowledge of what time and temperature combinations would inactivate pathogenic bacteria in milk, and so a number of different pasteurization standards were in use.
