United States raw milk debate temperatures may be used by different processors, pasteurization is most commonly achieved with heating to 161 degrees Fahrenheit (71.7 degrees Celsius) for 15 seconds. Milk is tested following pasteurization to confirm that bacteria have been killed to an acceptable level. Pasteurization kills pathogenic bacteria which occasionally may be present in milk, including those causing tuberculosis ("Mycobacterium bovis"), listeriosis ("Listeria monocytogenes"), Q fever ("Coxiella burnetii"), brucellosis ("Brucella"), campylobacteriosis ("Campylobacter"), salmonellosis ("Salmonella"), and several other foodborne illnesses (e.g., ). Pasteurization may not kill some resistant bacteria, which can eventually cause souring and spoilage of fresh milk. UHT pasteurization (Ultra High Temperature) is
Swine brucellosis Swine brucellosis Swine brucellosis is a zoonosis affecting pigs, caused by the bacterium "Brucella suis". The disease typically causes chronic inflammatory lesions in the reproductive organs of susceptible animals or orchitis, and may even affect joints and other organs. The most common symptom is abortion in pregnant susceptible sows at any stage of gestation. Other manifestations are temporary or permanent sterility, lameness, posterior paralysis, spondylitis, and abscess formation. It is transmitted mainly by ingestion of infected tissues or fluids, semen during breeding, and suckling infected animals. Since brucellosis threatens the food supply and causes undulant fever, "Brucella suis" and other
