Since 1987, Porcine Reproductive and Respiratory Syndrome virus (PRRS) has become a global drain on pig productivity, profitability, and many a producers’ morale. One thing that remains certain is PRRS virus continually finds ways to circumvent our best bio-management efforts. PRRS marches on in a ceaseless continuum of antigenic change making current vaccines and other control techniques of limited value.

The cleaning and disinfection process are critical steps in any biosecurity program in order to minimize the transmission of diseases. Washing is the most critical step of the entire process. This step will remove over 99% of the microorganisms.

Pathogens which are highly infectious and only require small doses to establish infection in susceptible pigs and/or those which are able to survive environmentally for relatively long periods can be spread from farm to farm as fomites

Trailers contaminated with PRRSV can serve as a source of infection for naïve pigs. Therefore, sanitation for livestock trailers and transport vehicles is considered a high priority when it comes to biosecurity practices.
