Argentina According to a study published in 2002, an estimated 10–13% of farm animals are infected with Brucella species. Annual losses from the disease were calculated at around $60 million. Since 1932, government agencies have undertaken efforts to contain the disease. Currently, all cattle of ages 3–8 months must receive the Brucella abortus strain 19 vaccine. Australia Australia is free of cattle<unk> , although it occurred in the past.<unk>  of sheep or goats has never been reported.<unk>  of pigs does occur. Feral pigs are the typical source of human infections. Canada On 19 September 1985, the Canadian government declared its cattle population<unk> -free.<unk>  ring testing of milk and cream, and testing of cattle to be slaughtered ended on 1 April 1999. Monitoring continues through testing at auction markets, through standard disease-reporting procedures, and through testing of cattle being qualified for export to countries other than the United States. China An outbreak infecting humans took place in Lanzhou in 2020 after the Lanzhou Biopharmaceutical Plant, which was involved in vaccine production, accidentally pumped out the bacteria into the atmosphere in exhaust air due to use of expired disinfectant. The outbreak affected over 6,000 people. Europe Disease incidence map of B. melitensis infections in animals in Europe during the first half of 2006 Malta Until the early 20th century, the disease was endemic in Malta to the point of it being referred to as "Maltese fever". Since 2005, due to a strict regimen of certification of milk animals and widespread use of pasteurization, the illness has been eradicated from Malta. Republic of Ireland Ireland was declared free of<unk>  on 1 July 2009. The disease had troubled the country's farmers and veterinarians for several decades. The Irish government submitted an application to the European Commission, which verified that Ireland had been liberated. Brendan Smith, Ireland's then Minister for Agriculture, Food and the Marine, said the elimination of<unk>  was "a landmark in the history of disease eradication in Ireland". Ireland's Department of Agriculture, Food and the Marine intends to reduce its<unk>  eradication programme now that eradication has been confirmed. UK Mainland Britain has been free of<unk>  since 1979, although there have been episodic re-introductions since. The last outbreak of<unk>  in Great Britain was in cattle in Cornwall in 2004. Northern Ireland was declared officially<unk> -free in 2015. New Zealand<unk>  in New Zealand is limited to sheep (B. ovis). The country is free of all other species of Brucella. United States Dairy herds in the U.S. are tested at least once a year to be certified<unk> -free with the Brucella milk ring test. Cows confirmed to be infected are often killed. In the United States, veterinarians are required to vaccinate all young stock, to further reduce the chance of zoonotic transmission. This vaccination is usually referred to as a "calfhood" vaccination. Most cattle receive a tattoo in one of their ears, serving as proof of their vaccination status. This tattoo also includes the last digit of the year they were born. The first state–federal cooperative efforts towards eradication of<unk>  caused by B. abortus in the U.S. began in 1934.<unk>  was originally imported to North America with non-native domestic cattle (Bos taurus), which transmitted the disease to wild bison (Bison bison) and elk (Cervus canadensis). No records exist of<unk>  in ungulates native to America until the early 19th century.
