Swine Bacterial Disease Matrix

The pork industry has spent millions to better understand viruses, however, it is often bacteria that kills the pig. In addition, current biosecurity practices are primarily devised to keep viruses out and potentially fail to address the endemic nature of bacteria in a herd. To go along with the Swine Health Information Center’s (SHIC) Swine Disease Matrix, a prioritized list of endemic and foreign swine viruses, a Bacterial Swine Disease Matrix has been developed. This new tool will guide a focused look at the US pork industry’s highest bacterial risks, while SHIC continues to remain focused on emerging viral pathogens. Both are important tools and part of SHIC’s mission to protect and enhance the health of the United States swine herd.
