Veterinary Services USDA Swine Program Initiatives and Updates: Collaborations to Achieve Results Troy T. Bigelow U.S. Department of Agriculture Animal and Plant Health Inspection Service Veterinary Services April 1, 2014
Veterinary Services Swine Health Programs Overview • Update on surveillance and program activities • PRV, SB, CSF, IAV-S • PEDV collaborations • VS swine health activities towards enhancing surveillance • Next steps
Veterinary Services Swine Surveillance Pseudorabies FY 13
Veterinary Services Swine Surveillance • Pseudorabies • States submitting samples from herds with high probability of contact with feral swine receiving positives and coordinating traceback • 99.9 percent of domestic swine samples were negative • 21 percent of feral swine tested positive (FY13 convenience samples)
Hotspot Analysis Slide provided by VS, STAS,CEAH
Veterinary Services Swine Surveillance • FY14 PRV initiatives: • TAIO? Tool for assessment of intervention options (part of overall comprehensive TAIO) • Collaborating with industry on PRV sample reduction initiatives • Collaboration with States high risk samples • Updating list of high risk states • Improve the capture of State and premises identifying information on market slaughter (meat juice) and NAHLN samples
Veterinary Services Swine Surveillance • Swine Brucellosis FY 13 • TAIO? • Collaborating industry on SB sample reduction. • Implementing SB into NAHLN system
Veterinary Services Swine Surveillance • Classical Swine Fever • Goals of rapidly detecting disease • Targets 5 areas • Waste feeder/backyard (high priority) • Sick pig specimens to VDL • Slaughter swine with risks • Feral swine • FAD investigations
Veterinary Services Swine Surveillance (CSF) Even with PEDV highlighting the importance of rapid detection, zero swine FAD’s were reported in FY13
Veterinary Services Swine Surveillance CSF Improvement • Improve data quality (no state of origin reported) • Continue efforts to transfer CSF serology to NAHLN laboratories • Promote correct VS form usage for collection of samples • Explore CSF testing platform possibilities
Veterinary Services Swine Surveillance Influenza A Virus in Swine
Influenza A Virus in Swine Veterinary Services Swine Surveillance
PEDV Activities • PEDV • Confirmed by NVSL in May 2013 • VS cooperation with states and industry • Conference calls • Notifications • VS is actively participating in: • Risk assessments, diagnostic testing (including bioassays), assisting in epidemiological investigations to determine route of disease spread, strategic task force, disease reporting, supporting research • VS NAHLN is instrumental, information reporting
Collaborations to Achieve Results • What is Comprehensive Integrated Surveillance (CIS)? • CIS is a standardized data collection and information management approach that facilitates designed sample targeting in response to multiple and evolving swine health information needs. • October, 2013 -USAHA resolution update of Comprehensive Integrated Surveillance in Swine (CISS) activities on implementing surveillance through appropriate surveillance streams and results.
CISS- Collaborations to Achieve Results Surveillance activities • Disease updates-previous slides • Planning for FAD surveillance • Non-regulatory surveillance and information. • Influenza A virus in swine. • PEDV information coordination
CISS- Collaborations to Achieve Results CISS – Completed tasks • Initiated discussions on data standards with states. • Result reporting to stakeholders • Validated diagnostic methods (ASF, CSF, FMD, PRV) • Pilot project on utilizing Prem ID tags
CISS- Collaborations to Achieve Results Completed tasks • Developed surveillance strategies for FMD, ASF surveillance pilots • Developed methods for sample collection, testing and data messaging including NAHLN network. • PEDV- receiving network data sharing from 12+NAHLN labs. (4,000 PEDV testing records every week from NAHLN labs.)
CISS- Collaborations to Achieve Results Areas for improvement: • Consistency • State support on individual premises data sharing agreements varies. • Continued discussions among all parties in sharing premises information with VS • Testing efficiencies -targeting • Information technology infrastructure
CISS-Collaborations to Achieve Results CISS -Conclusion • VS cannot implement CIS alone, nor can the States or industry. • CISS must operate as a unified system with participation and support from all stakeholders to be effective. • To date, access to needed premises data is missing. • All parties must reach consensus on ways to share premises identifiers.
Collaborations to Achieve Results • VS-Next steps • Continue collaboration with stakeholders to enhance current surveillance structure • Enhance surveillance by adding future diseases of concern • Collaborate to overcome the next CISS data constrains
Other VS Activities • Risk Analyses • October, 2013 USAHA resolution seeking support and collaboration • Risk analyses regarding the introduction of diseases via production inputs sourced from outside US.
Other VS Activities • Pathway Assessment • VS has initiated a pathway assessment for exotic viral diseases of swine • The assessment is to determine whether significant gaps exist in commodities imported • VS is analyzing the likelihood of disease entering the country from a various pathways such as processing of feed materials, transport, equipment import mitigation procedures, etc. • VS plans sharing results with stakeholders
