is a Risk of Disease Transmission in Pig Transportation
PIC has been a leader in transportation biosecurity since its entry into the
breeding stock business in North America. PIC drivers and farm staff alike are
trained on the importance of following science-based protocols for loading and
unloading animals, cleaning and disinfection of the trailers, as well as with
all equipment used both inside and outside of the farm.
After the PRRS virus was identified, PIC worked with researchers to assure
procedures were effective to deactivate the virus. Early research with Drs.
Amass, Harris and Dee identified steps needed to reduce risk of spreading the
disease through transportation.
Research demonstrated the importance of drying as a critical step, helping to
assure year-round effectiveness of the total process. PIC coined the acronym
“TADD”, Thermal Assisted Drying and Decontamination, as a critical step to
inactivate PRRS virus and other pathogens.
With increasing concerns about transmission of Brachyspira, additional
emphasis was applied on cleaning the equipment to prevent fecal oral
transmission. Coronavirus outbreaks experienced by the industry in the last
year, have made it even more important to ensure all cleaning, disinfecting and
drying steps are performed consistently.
PIC has developed multiple documents (below) that are available for the
training process of anyone working in the transportation arena. Recent research
at Iowa State with Dr. Derald Holtkamp has confirmed the effectiveness of
washing with a detergent, disinfecting with the proper concentration of
disinfectant, and various contact times of a combination of heat and temperature
to deactivate the PED virus. The National Pork Board also has information on its
website with training materials
