Bovine paratuberculosis, also known as Johne’s disease, is a pathology caused by the bacterium Mycobacterium avium subsp. paratuberculosis (MAP), which is characterized by chronic intestinal injury.
It’s a disease distributed worldwide with a considerable economic impact on production due to its negative consequences on milk yield and the greater predisposition to the development of other pathologies or lower the commercial value of animals. The infection is mainly transmitted through the contact through feces between animals and by contaminated colostrum or milk intake from an infected animal.
The presence of MAP in milk and dairy products is a food safety concern due to its possible relationship with various human diseases, such as Crohn’s disease or type 1 diabetes. Therefore, detecting MAP in milk and slaughtering animals that excrete MAP can help improve consumer safety.
