Biosecurity considerations for pork production units

Abstract

This paper summarizes and critiques the peer-reviewed literature concerning biosecurity considerations in the pork industry. Manuscripts concerning source of genetic material and segregation procedures were examined to address the risks of introduction of new genetics. Other biosecurity risks reviewed include transmission of pathogens by aerosol, birds, insects, nonporcine animals, and vehicles; and pathogen survival in dead pigs, feed, manure, water, and soil. Many decisions regarding biosecurity protocols on pork production units are currently based on producer and veterinary experience and opinion, not on scientific research. Consequently, research is needed in many areas either to validate current protocols or to develop new scientifically sound biosecurity measures for the pork industry.
