1. Immediate destruction of infected and in-contact animals generally in emergency situations such as response to an exotic disease outbreak (for example, foot-and-mouth eradication programs, bovine spongiform encephalopathy).
2. Test-and-slaughter programs have often been used in the past for eradication of specific diseases (bovine brucellosis and tuberculosis in Australia). In this case animals are tested and only those that are deemed to be disease positive are then slaughtered.
3. Herd depopulation may be used in extreme situations or for problem herds where eradication using other methods has failed (for example, foot-and-mouth disease, bovine spongiform encephalopathy in the UK; problem herds for bovine tuberculosis and brucellosis late in the Australian brucellosis and tuberculosis eradication programs)
4. Slaughter or early culling of individual animals may also be used in non-emergency situations as part of a voluntary or regulatory control program for some diseases (for example footrot or ovine brucellosis in sheep, chronic mastitis in dairy cows).
