The last outbreak of brucellosis in Great Britain was in cattle in Cornwall in 2004. Northern Ireland was declared officially brucellosis-free in 2015. New Zealand
Brucellosis 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 brucellosis-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 brucellosis caused by B. abortus in the U.S. began in 1934.Brucellosis 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 brucellosis in ungulates native to America until the early 19th century. History
Brucellosis first came to the attention of British medical officers in the 1850s in Malta during the Crimean War, and was referred to as Malta Fever. Jeffery Allen Marston (1831–1911) described his own case of the disease in 1861. The causal relationship between organism and disease was first established in 1887 by David Bruce.
Hunters should refer to local game officials and health departments to determine the risk of brucellosis exposure in their immediate area and to learn more about actions to reduce or avoid exposure. See also
