Desafios da listeriose na produção pecuária: uma breve revisão

Abstract

This work is a literature review on listeriosis, a disease caused by the bacterium Listeria monocytogenes. This disease is usually associated with the consumption of poor quality food and the presence of decomposing organic matter in the environment, and can affect mammals, including ruminants, monogastric animals and humans. Listeriosis is a disease that in domestic animals can trigger a series of clinical changes, being difficult to control, because its pathogen can be present on any surface of the environment. Encephalitis cases are the most common among the species and cause direct economic losses, either through the death of animals or the need for euthanasia, medication expenses, decreased production and sporadic cases of abortions. Listeria monocytogenes, the main species causing listeriosis, has been isolated from different products of animal origin such as raw milk, beef, pork, poultry, fish, sausages, as well as products of plant origin that have not had the proper cleaning process. The presence of the bacteria in foods of animal origin is due to the natural presence of this microorganism in the gastrointestinal system of these animals. The study of this topic will be based on a bibliographic review to understand the importance of approaching this subject, especially in the area of livestock production.
