SHIC Receives Extension from National Pork Board and Reviews 2019 Results

Ames, Iowa — When the Swine Health Information Center (SHIC) was formed July 1, 2015, it was with the understanding it was a five-year project. The proposal language surrounding the Center’s formation stated, “Funding of the Center past its five-year life will depend on it being able to demonstrate a sufficient return on the investment to justify keeping it running.” Following presentation and approval of SHIC’s 2019 Progress Report on January 7, 2020, the National Pork Board (NPB) Board of Directors voted to extend the project for two more years, using SHIC’s existing funds. NPB also agreed to continued consideration of future funding and coordination beyond the two-year extension. In the 2019 report, it is clear African swine fever (ASF) required significant resources, however, SHIC remained faithful to its mission to protect the health of the US swine herd through comprehensive preparedness, monitoring, response, and communications activities. The 2019 Progress Report details progress in each of these areas.

Preparedness Activities on Behalf of US Swine Herd Health

Developed the Diagnostic Assay Catalog which includes polymerase chain reaction (PCR) assays and enzyme linked immunosorbent assays (ELISAs) for detection of emerging disease and made available to all diagnostic labs
Developed PCR and ELISA tools now widely available to labs in the US
Researched priority pathogens porcine circovirus 3 (PCV3), foot-and-mouth disease (FMD), and African swine fever (ASF)
Administered USDA-Foreign Ag Service grant to fund the analysis of Vietnamese field oral fluid samples
International transportation biosecurity practices of four cooperating US breeding stock companies were analyzed
Due to a Senecavirus A (SVA) outbreak in Brazil, investigated the possibility a Brazilian feed mill and/or its ingredients could be a source of the pathogen’s transmission

Monitoring Swine Disease Transmission Vectors

SHIC and the National Pork Board (NPB) co-funded a project analyzing the risk of ASF and classical swine fever (CSF) being introduced into the US through prohibited swine products by air passengers
Joined with the American Association of Swine Veterinarians (AASV), National Pork Producers Council (NPPC) and NPB to meet multiple times with the Department of Homeland Security (DHS) Customs and Border Protection (CBP) during 2019 to voice concerns about the lack of secondary screening of travelers after declaring contact with foreign farms or animals relating to ASF and FAD threats

Improving Transport Biosecurity Domestically

Investigating Common Inputs as Vectors for Disease Introduction

Kansas State University project improved the half-life calculations of ASF in feed ingredients exposed to transatlantic shipment conditions
Examined 14 feed additives to determine their ability to negatively affect viral survival and be cost-effective mitigants
Encouraged the American Feed Industry Association (AFIA) as they updated feed mill biosecurity guidelines
Participated in a feed processor ASF task force to define prevention, detection, and response protocols for feed ingredients, feed manufacture, and on-farm feed delivery
Sponsored a workshop to increase understanding of the vitamin supply chain and identify potential risk factors for introducing foreign animal disease to the US
Brought together soybean industry stakeholders to increase understanding of the soy supply chain and identify potential risk factors for introducing foreign animal disease into the US

Improving Swine Health Information

Continued to support the Morrison Swine Health Monitoring Project (MSHMP) which monitors approximately 50% of the US sow herd for economically important pathogens
Described key differences in the biosecurity aspects of breeding herds with relatively low porcine reproductive and respiratory syndrome (PRRS) incidence, compared to those with relatively high PRRS incidence
Funded a study applying machine-learning to predict porcine epidemic diarrhea virus (PED) outbreaks on sow farms
Funded thorough study of the National Poultry Improvement Plan (NPIP), its associated organizational structure and operations, and industry participation and execution across the various segments of the US poultry industry to assess the potential for establishing a similar program for the US swine industry

Surveillance and Discovery of Emerging Disease

New variant of porcine sapovirus identified in 2019 and appears to be the first detection of a single porcine sapovirus infection in piglets with diarrhea in the US
Real time RT-PCR to detect viral RNA in clinical samples and determine the viral load being developed
Developed and evaluated a serum/oral fluid ELISA to detect antibodies against atypical porcine pestivirus (APPV)
Improvements made toward a nationally coordinated swine health surveillance system to prepare, detect and rapidly respond to emerging and foreign animal diseases were investigated
Streptococcus equi ssp zooepidemicus confirmed in assembly yards resulting in isolates being sequenced, a species-specific PCR being developed, and a challenge study being done
Continued further diagnostic work into understanding a hemorrhagic tracheitis syndrome in Canada

Responding to Emerging Disease

US pork industry created the National Swine Disease Council made up of key industry leaders, the North American Meat Institute and representatives from SHIC, NPB, NPPC, and AASV along with USDA and state animal health official representation
In collaboration with AASV, held a webinar titled Disease Management of Viral Myelitis for veterinary practitioners and pork producers.

African Swine Fever

Funded a project to report the current state of knowledge regarding possible strain differences and pathogenicity of ASF
USDA-Foreign Ag Service grant awarded to SHIC, with active support from NPPC, funds project in Vietnam helping to build strategic partnerships while increasing trade of US pork to the region including swine health field projects ultimately informing North American pork producers about effective ASF preparedness and response

Funded by America’s pork producers to protect and enhance the health of the US swine herd, the Swine Health Information Center focuses its efforts on prevention, preparedness, and response. As a conduit of information and research, SHIC encourages sharing of its publications and research for the benefit of swine health. Forward, reprint, and quote SHIC material freely.
