About the Wean-to-Harvest Biosecurity Program
SHIC, along with the Foundation for Food & Agriculture Research (FFAR) and Pork Checkoff joined together to fund a Wean-to-Harvest Biosecurity Program to be implemented over two years. Phase I involved identifying subject matter experts and assembling task forces with the responsibility of establishing research priorities. Phase II investigates cost-effective, innovative technologies, protocols or ideas to implement biosecurity during the wean-to-harvest phase of production.
Proactively enhancing wean-to-harvest biosecurity will help control the next emerging disease in the U.S. pork industry and improve U.S. swine herd health.
Priorities for the research proposals reflect input from key industry stakeholders recruited to join the SHIC Wean-to-Harvest Biosecurity Program Site Task Force and Transport Task Force. These experts come from allied industry, academia, veterinary practice and organizations involved in pork production. Collectively, their experience and interest reflect contemporary issues related to wean-to-harvest biosecurity. Working at a rapid pace, each Task Force has met virtually several times to develop and refine priorities for the research proposals now requested.
Research Biosecurity Priorities
1) Personnel biocontainment and bioexclusion
- Compare implementation and compliance incentives and/or rewards and their successes, shortcomings, or adoption barriers across sites or systems to help understand worker motivation to consistently execute biocontainment and/or bioexclusion protocols.
- Investigate innovative, biosecurity-effective, and cost-effective alternatives to the “shower in” and “shower out” facilities and protocols currently used by personnel – find an enhanced “next generation” PPE or Danish Bench system.
- Investigate biocontainment or bioexclusion engineering controls (modifying equipment, physical barriers, site design, ventilation, robotics, or other technologies) that will help overcome labor shortages and the need to share personnel, such as with loading, vaccination, or cleaning and disinfection crews, across sites in a production or contracting service network.
- Identify pathways for pathogen introduction or movement from truck driver activities within the truck, at loading/unloading, or across a contracting service network and validate technologies or techniques to decrease these risks.
- Investigate innovative facility designs that can be retrofitted into existing facilities to inherently increase biosecurity during pig loading (modifying chute or loading area, permanent infrastructure, designing physical barriers) to increase effectiveness of staged loading.
2) Mortality management
- Investigate innovative engineering, containment technologies, equipment, or facility design solutions to prevent mechanical vectors, aerosols, and secretions from causing pathogen transmission from mortality holding boxes, their surrounding environment, and/or rendering pickup to the pig growing facilities.
3) Truck wash efficiency
- Investigate innovative ideas to increase throughput in truck wash facilities. Projects must demonstrate increased throughput while maintaining or improving efficacy across trailer configurations and styles. Examples could include:
- Engineering, mechanical, or robotic solutions
- Cost-effective, novel washing or disinfecting technologies
- Investigate cost-effective technologies that can be applied to existing trailer designs and configurations to improve ease of cleaning and disinfection. Examples could include cost-effective alternatives that eliminate the need for bedding or use novel bedding materials (other than wood shavings) and/or floor coverings or floor 3 coatings that could be more efficiently removed or cleaned to facilitate trailer cleaning and disinfection.
4) Alternatives to fixed truck wash
- Design or demonstrate deployable techniques, mobile systems or temporary structures for interior trailer cleaning and disinfection with water that are either season-specific or, preferably, that can be applied across seasons and that provide solutions to waste and bedding removal, water sourcing, and wastewater management. Consideration should be given to:
- Technologies and techniques to focus on cleaning and disinfection efficacy
- Time needed to complete the cleaning and disinfection process
- Cost of implementation
- Design or demonstrate deployable techniques, mobile systems or temporary structures for interior trailer cleaning and disinfection without water that are either season-specific or, preferably, that can be applied across seasons that consider waste and bedding removal. When applying cleaning and disinfection processes, potential impact of application on the lifespan of the truck and trailer equipment should be assessed. Consideration should be given to:
- Technologies and techniques to focus on cleaning and disinfection efficacy
- Time needed to complete the cleaning and disinfection process
- Cost of implementation
- Examples may include the sequence or combination of mechanical blow out or vacuuming of trailer contents, scraping, application of heat or steam, and/or fogging or gas disinfectants, along with shrouding or other innovative ways to facilitate disinfection.
5) Packing plant or other first point of concentration biocontainment
- Investigate and validate innovative techniques and/or technologies that can be applied at the unloading docks at markets, packing plants, and other first points of concentration, including entry and exit to these sites, to demonstrate decrease of the pathogen load and the opportunity for tractors and trailers to transfer pathogens from these facilities back to the farm.
- Objectively track and demonstrate high risk driver and plant personnel traffic patterns and movements and investigate interventions to mitigate these risks. Among other mitigations, implementing electronic technologies to eliminate the need for physical document transfer between driver and plant could be considered.
- Investigate diagnostic sampling or monitoring protocols to identify areas of highest concentration of pathogens within packing plants or secondary markets.
The Swine Health Information Center, launched in 2015 with Pork Checkoff funding, protects and enhances the health of the U.S. swine herd by minimizing the impact of disease threats through preparedness, coordinated communications, global disease monitoring, analysis of swine health data, and targeted research investments. As a conduit of information and research, SHIC encourages sharing of its publications and research.
