2 Overview What we do: FMD/ASF Pilot Objectives Goals Activities Comprehensive Integrated Surveillance (CIS) SECD Emerging Diseases Procedures when a FAD is suspected Picture from Wikipedia of Corona Virus 2

3 Background Foreign Animal Diseases- US Status Foot and Mouth Disease (FMD)-FREE Classical Swine Fever (CSF)-FREE African Swine Fever (ASF)-FREE 3

4 ASF/FMD Surveillance Pilot Overarching goal Support substantiation of freedom for swine foreign animal diseases (FADs) 4

5 ASF and FMD Surveillance Pilot Purpose and Rational for Surveillance Maintaining international market confidence Protecting the economy of the U.S. livestock industry Protecting the health and well-being of the Nation s meat / milk herds and flocks Increasing the levels of diagnostic testing preparedness and diagnostic capabilities 5

6 ASF and FMD Surveillance Pilot Objectives: Enhance awareness for the reporting /collection of samples from cases compatible with ASF and FMD Implement active diagnostic testing for ASF and FMD surveillance in eight authorized laboratories from the NAHLN Collect baseline surveillance information from surveillance streams that could be used to substantiate ASF and FMD disease freedom and to monitor for early detection of disease 6

7 ASF and FMD Surveillance Pilot Exercise a communication plan for potential suspect cases of ASF and FMD and ensure that all parties involved understand the communication process and implement it in an effective and timely manner Increase diagnostic preparedness and provide the laboratory testing network with an exercise for a potential outbreak 7

8 ASF and FMD Surveillance Pilot 12 month pilot/8 approved NAHLN labs Sept FMD implemented February ASF implemented Notification plan = handled same as CSF ASF or FMD suspected FAD investigation Surveillance streams = CSF Test: rrt-pcr Sample types ASF = whole blood (EDTA) FMD= oral swabs FADDL validation of additional tests and tissues 8

9 ASF and FMD Surveillance Pilot Sample sources Laboratory submissions of whole sick pigs On-farm collection of swine samples from licensed feeders under the Swine Health Protection Act (aka garbage feeders) On-farm collections from swine in known premises with feral swine exposure Slaughter samples collected from FSIS due to septicemia and other ante and post mortem condemn reasons 9

10 ASF and FMD Surveillance Pilot Sample sources cont. o o Samples collected at slaughter plants in states having higher risk for CSF (Florida, Texas, Puerto Rico) Swine suspected to have ASF, FMD, or CSF and included for testing as part of an FAD investigation. Duplicate samples will be tested in the NAHLN laboratory and at the National Veterinary Services Laboratories (NVSL) Foreign Animal Disease Diagnostic Laboratory (FADDL), where confirmatory test results will be issued. 10

11 LMS ASF/FMD Data Submission Program Guide Messaging specifications for the NAHLN labs Collection site Reason for Submission Comparison of data on the submission form to messaged values Date of birth/age class 11

12 ASF and FMD Surveillance Pilot Pilot testing completed Aug samples for FMD Data is being analyzed prior to full program implementation Preliminary data indicates pilot was successful in identifying areas for improvement such as Surveillance data management Field operations/implementation Diagnostic validations 12

13 CIS-Comprehensive Integrated Surveillance What is CIS? An approach to animal disease surveillance that connects and engages partners in animal heath Exchanging information to maintain animal health knowledge Evaluation and improvement process allowing increase or decrease of animal surveillance needs 13

14 CIS Components Field operations resources for surveillance; Sources for surveillance information and surveillance streams. Veterinary Diagnostic infrastructure, lab network, and messaging; Systems for data collection, management, storage, analysis and reporting; Methodologies for data analysis and communicating reports; 14

15 Surveillance activities for CIS include testing for Swine brucellosis Pseudorabies Classical Swine Fever Influenza SECD Pilot FMD/ASF CIS 15
