Caseous lymphadenitis (CLA), also called pseudotuberculosis, is a chronic and highly infectious disease of sheep and goats, subject to obligatory registration in the European Union. The EU law also applies to special territories, which include the Falkland Islands. On the Falkland Islands 99% of sheep and goats are slaughtered in one slaughterhouse, overseen by veterinary authorities, and approved for export to EU countries (mainly the UK). The export season begins about the middle of January and usually lasts 3-4 months. In the years 2013-2015 were examined 162 317 sheep, including 39 971 lambs, 35 357 yearlings and 86 989 mature rams. During the study lung tissue clippings were collected. During the 2013 season lesions were observed in 8 025 of animals (13.9% CLA). In 2014 lesions were noted in 7716 with CLA accounting for 13.91% and in 2015 lesions were noted in 5743 with CLA accounting for 11.7%. Further analysis of cases of CLA on the Falkland Islands seems interesting, as they are British overseas territories and therefore part of the European Union.
