The need for stringent screening increased the cost of operating milk banks, forcing them to close doors. Improved screening methods and standardization of procedure have made donated milk a viable alternative to mother's breast milk. The ability to pasteurize and store breast milk for up to 8 months means milk banking could become a global enterprise.

The smoke from the embers also has a preservative effect which prevents undesired bacterial multiplication that causes spoilage, while allowing natural souring. The charcoal smoke imparts a special flavour to the milk, and a bluish colour which is of high aesthetic value to the consumer. Having prepared the gourd, women pasteurize the milk by boiling. The pasteurized milk is left to cool before pouring into the gourd.

The USDA approved a proposal by the Almond Board of California to pasteurize almonds sold to the public, after tracing cases of salmonellosis to almonds. The almond pasteurization program became mandatory for California companies in 2007. Raw, untreated California almonds have not been available in the U.S. since then. California almonds labeled "raw" must be steam-pasteurized or chemically treated with propylene oxide (PPO).

There had been three multimillion-dollar expansions since 1985 to provide more efficient production and distribution of dairy products. Trauth Dairy was one of the first dairies in the area to vacuum pasteurize milk, and the first in Cincinnati to introduce tamper-evident packaging for sour cream, cottage cheese and dips. Trauth Dairy was the sole manufacturer of Fat Free plus a/B milk. In 1997, the company was sold to Suiza Food Corp for an undisclosed price.

Spoilage microorganisms and some enzymes can be deactivated by HPP, which can extend the shelf life while preserving the sensory and nutritional characteristics of the product. Pathogenic microorganisms such as Listeria, E. coli, Salmonella, and Vibrio are also sensitive to pressures of 400-1000 MPa used during HPP. Thus, HPP can pasteurize food products with decreased processing time, reduced energy usage, and less waste. The treatment occurs at low temperatures and does not include the use of food additives.

The WHO infant feeding guidelines advise the use of donor milk when the mother's milk is not available. With the understanding that breast milk provides immune protection that is absent in formula, mothers have turned to milk sharing options to in order to give formula alternatives to their infants. A donation of milk without monetary benefit defines milk sharing. In addition, milk banks have emerged to regulate and pasteurize donated milk to be sold in the legal market.

Irradiation can be used to pasteurize food products, such as seafood, poultry, and red meat, thus making these food products safer for consumers. Some irradiation is also used to delay fruit ripening processes, which can kill microorganisms that accelerate the ripening and spoilage of produce. Low dosages of radiation can also be used to kill insects living in harvested crops, as the radiation will stunt the insects' development at various stages and damage their ability to reproduce.

The Minden Butter Manufacturing Company, also known as the Minden Creamery, is a historic creamery building located at 1617 Water St. in Minden, Nevada. Built in 1916, the creamery was designed by noted Nevada architect Frederic Joseph DeLongchamps. The creamery replaced the Minden Butter Manufacturing Company's first building, which was built in 1908, so the company would have space to pasteurize its products. The company sold butter and other produce under the Windmill brand name and eventually became the largest creamery in Nevada.

Other thermal and non-thermal processes have been developed to pasteurize foods as a way of reducing the effects on nutritional and sensory characteristics of foods and preventing degradation of heat-labile nutrients. Pascalization or high pressure processing (HPP) and pulsed electric field (PEF) are examples of these non-thermal pasteurization methods that are currently commercially utilized. Microwave volumetric heating (MVH) is the newest available pasteurization technology. It uses microwaves to heat liquids, suspensions, or semi-solids in a continuous flow.

Steam infusion can be used to pasteurize a variety of dairy products. For ultra pasteurization, also known as ultrahigh-temperature (UHT) pasteurization, the milk is heated to temperatures in the order of 140 °C. During steam infusion, milk is brought into contact with steam at 140 °C for one or two seconds. The heating is instantaneous, and the milk is cooled rapidly by evaporative cooling exposure to a slight vacuum, removing any water added to the milk by condensation of the steam.

While in Heidelberg, Reba Hurn met Nathan Straus, co-owner of Macy's department store in New York City. He was in Germany to introduce his milk distribution charity, already established in American cities, whereby he provided safe, pasteurized milk to the poor. By preventing the transmission of bovine tuberculosis and other milk-borne diseases, Straus was able to reduce the shocking infant and child mortality of the period. Reba took a keen interest in his work, began volunteering, and learned to pasteurize milk.

The conversion cycle consists of several sequential steps or phases. The waste is first ground and pulverized to an unrecognizable mixture by a combination of fixed and actuated hardened steel blades. The mixture is then heated through the injection of steam and also by the heat generated by frictional forces of the grinding phase. The exact temperature required to pasteurize, and in the subsequent phase to sterilize the waste, is maintained for a time that allows for an 18 log 10 reduction in microorganisms.

Traditional cheese is ground, combined with emulsifying agents and other ingredients, mixed and heated until it forms a "melted homogeneous" mixture. To pasteurize it, the cheese mixture must be heated to a temperature of at least for a minimum of 30 seconds. Composition requirements of processed American cheese control the percentage of milkfat, moisture, salt and pH value in the final product, along with specifications for flavor, body and texture, color, and meltability. Processed American cheese is packaged in individually wrapped slices, as unwrapped slices sold in stacks, or in unsliced blocks.

In 1988, Francis R. Keeler patented a similar but smaller and more mobile version of the recycling shower for usage in motor homes, boats and airplanes. In 2011, Nick Christy of Australia won the Postcode Lottery Green Challenge, an annual competition for sustainable ideas for his version of the water recycling shower. The shower aimed to collect, filter, pasteurize and then dilute the water with fresh tap water to cool it again to the set temperature. Citing cultural problems and lack of traction in his native Australia, Christy aimed for the UK market.

The Odwalla plant had several food safety issues, many of which arose because Odwalla did not pasteurize its juice. Tests discovered low levels of Listeria monocytogenes, a pathogen that can harm pregnant women, at the Odwalla factory in 1995. In response, the company spent several million dollars to upgrade the plant's safety features, and bacteria were reduced to "relatively low levels". The next year, Dave Stevenson, Odwalla's technical services director who oversaw quality assurance, suggested to Odwalla executives that the company should add a chlorine rinse to guard against bacteria on the skin of processed fruit, supplementing its existing phosphoric acid wash process.

Hot dogs being cooked with a solar funnel cooker A solar cooker is a device which uses the energy of direct sunlight to heat, cook or pasteurize drink and other food materials. Many solar cookers currently in use are relatively inexpensive, low-tech devices, although some are as powerful or as expensive as traditional stoves, and advanced, large-scale solar cookers can cook for hundreds of people. Because they use no fuel and cost nothing to operate, many nonprofit organizations are promoting their use worldwide in order to help reduce fuel costs and air pollution, and to help slow down deforestation and desertification.

Thus dairy farms that pasteurize their milk can have unsanitary facilities without the attendant outbreaks of disease that would occur if a raw milk dairy kept its herds in similar unsanitary conditions. People with weakened immune systems, such as elderly, children, and those with certain diseases or conditions, are most at risk for severe infections from pathogens that can contaminate raw milk. In pregnant women, Listeria monocytogenes-caused illness can result in miscarriage, fetal death, or illness or death of a newborn infant, and Escherichia coli (E. coli) infection has been linked to hemolytic uremic syndrome, a condition that can cause kidney failure and death.

Ethylene oxide (EO, EtO) gas treatment is one of the common methods used to sterilize, pasteurize, or disinfect items because of its wide range of material compatibility. It is also used to process items that are sensitive to processing with other methods, such as radiation (gamma, electron beam, X-ray), heat (moist or dry), or other chemicals. Ethylene oxide treatment is the most common chemical sterilization method, used for approximately 70% of total sterilizations, and for over 50% of all disposable medical devices. Ethylene oxide treatment is generally carried out between with relative humidity above 30% and a gas concentration between 200 and 800 mg/l.

The technology of the clean cook stove has been dubbed "The Rocket Stove" because of the simple yet effective design. The cook stove has a large vertical cylinder that holds a pot and an opening at the bottom to feed the fuel to cook a meal or pasteurize drinking water. The combustion chamber of the Envirofit stoves use up to 60% less fuel than other stoves or open fires to reduce toxic emissions by up to 80%. The Envirofit stoves include the CH-4400 charcoal stove, the CH-5200 charcoal stove, the CH-2200 charcoal stove, the Z-3000 Built-In wood stove, the G-3300 wood stove, and the M-500.

Clostridium botulinum bacteria can grow in food in the absence of oxygen and produce the deadly botulinum toxin, so sous vide cooking must be performed under carefully controlled conditions to avoid botulism poisoning. Generally speaking, food that is heated and served within four hours is considered safe, but meat that is cooked for longer to tenderize must reach a temperature of at least within four hours and then be kept there for sufficient time, in order to pasteurize the meat. Pasteurization kills the botulism bacteria, but the possibility of hardy botulism spores surviving and reactivating once cool remains a concern as with many preserved foods, however processed. For that reason, Baldwin's treatise specifies precise chilling requirements for "cook-chill", so that the botulism spores do not have the opportunity to grow or propagate.

George Washington Goler, M.D. (born August 24, 1864, died September 18, 1940) was a pioneer in pediatrics. In addition to being the founder of the first prenatal clinic in the United States, he was the first to advocate a municipal department for the pasteurization of milk.Current Biography 1940, p344 After his appointment in 1896 as the Director of the Board of Health in Rochester, New York, Goler set about to reduce infant mortality. Following the efforts of New York City merchant Nathan Straus, who had provided pasteurized milk at cost to residents of tenements, Goler organized a station for the purification and distribution of milk.Albert Joseph Kennedy and, Robert Archey Woods, The Settlement horizon: A National Estimate (Russell Sage Foundation, 1922) During the months of July and August 1897, when infant deaths were at their highest, Goler arranged for an Infants' Milk Depot to be set up in a storefront in Rochester, with two nurses to pasteurize and cool milk, then to sell it at cost to mothers of small children.
