Abstract

Animal food-borne microbes are pathogens that jeopardize food safety and cause illness in humans via natural infection or contamination. Most of those microbes are bacteria that have considerable impacts on public health. Their survival and pathogenicity are due to toxin production, biofilm development, spore formation, disinfection resistance, and other traits. However, detailed information about them is scattered across scientific literature.
We aimed to compile information about major zoonotic bacteria linked with human food of livestock origin and describe their typical features, transmission modes, detection, and preventative approaches. In particular, we addressed the following pathogens that cause food-borne disease worldwide: Campylobacter, Salmonella, Listeria, Staphylococcus, Brucella, Clostridium, Mycobacterium, Colibacilus, and some others.
Many of those bacteria have substantial reservoirs in food animals, and food products of animal origin are the primary vehicles of their transmission. Human beings become affected by food-borne zoonotic bacteria if they consume raw animal products or foods produced by using unstandardized slaughtering methods or unsanitary preparation and handling procedures. These zoonotic bacteria and their toxins can be detected in food by culturing, serological, and molecular diagnostic methods. They are effectively controlled and prevented by good hygiene, good management practices, cooking, and pasteurization protocols.
In addition, there is a need for a centralized surveillance and monitoring system, as well as higher awareness in society of the occurrence, prevention, and control of bacterial pathogens related to food animals.

Keywords
