• Initiate and facilitate national animal health
  programs which promote or improve U.S. animal
  health, by preventing, minimizing, or eradicating
  animal diseases of economic concern
• TB Eradication
• PRV Eradication
• Brucellosis Eradication
• Animal Identification Program (NAIS)
• National Aquaculture Program

PRV Eradication

• PRV FY 2009
• WR 3 positive transitional herds/animals
  identified
• TX (3) - one repeat herd- not indemnified with
  USDA funds.
• ER 3 positive herds
• FL (3) Two of these herds were dually infected
  with SB

Swine Brucellosis Eradication

• Swine brucellosis FY 2009
• ER 4 transitional () herds indemnified SB
• Georgia (2)
• Florida (2) These herds were dually infected with
  PRV

PRV Surveillance Plan

• Implementation progress
• Changes to existing surveillance streams
• Sow boar slaughter surveillance, Jan 2009
• Decrease to 5 as the required surveillance
  program for free SB and PRV states
• Two labs (KY and KS)
• Discarding samples to the 5 rate
• Samples from slaughter plants
• Cooperative agreement changes done by Regions
• Meat juice of market hogs-continues at decreased
  level

12
PRV Surveillance Plan

• New surveillance streams
• Rapid Detection Streams
• NAHLN Laboratory
• Convenience serology sampling, will begin late
  spring to early summer 2009
• PCR for antigen detection to begin once the test
  is validated.
• Herds with confirmed exposure to feral swine
  testing
• To implement late 2009
• IT development progressing
• Next up Swine Brucellosis

13
Feral Swine

• Populations are increasing
• Reservoirs of disease
• PRV
• Brucella Suis
• Parasites
• PRRS, etc.
• Real-time mapping accomplished with cooperative
  agreement

14
New Feral Swine Map
15
Trichinae Certification Program

• Rule finalized in November 2008
• Voluntary certification program
• Program certifies pork production sites following
  good production practices that reduce or
  eliminate risk of Trichinella
• Facilitates exports of pork

16
Swine Health Protection Act

• FY 2008 - 2783 licensed premises
• 1964 in PR
• Inspections of licensed premises
• 8747 premise inspections
• 1199 temperature checks
• 219 violations
• 37,037 Inspections for non-licensed feeders
• 104 non-licensed feeders IDed
• All increased over FY 2007

Classical Swine Fever Surveillance

• Goal is to integrate field sample collection and
  NAHLN lab PCR-based testing and FADDL serum
  testing via a coordinated plan
• Sample sources
• Slaughter plant condemnation sampling (tonsil) -
  pyrexia, erysipelas, etc.
• Diagnostic Laboratory-based surveillance of
  tissue submitted from sick pigs (tonsil)
• Feral swine (all serology starting in 2007)
• Puerto Rico - intensive surveillance
• Yola landing 3K surveillance (all serology)
• TX and FL non-commercial slaughter plants
  (serology and PCR)
• Garbage feeding sites in high risk states (2007
  all serology)

19
CSF Surveillance FY08

• Sick pigs sampled at diagnostic labs 3187
• Slaughter swine sampled 1602
• Feral swine sampled 2302
• Swine from high risk herds sampled (garbage
  feeders and high risk FL, TX, and PR herds)
  11,244
• Swine FAD investigations 12
• All negative for CSF

21
Foot and Mouth Disease Surveillance

• FMD surveillance plan developed by NSU
• FMD surveillance plan has various testing streams
• Laboratory (all susceptible species)
• Observational component (select livestock
  markets)
• Feral Swine Surveillance
• Pilot project implemented in the near future

22
Swine Influenza Surveillance

• A collaborative pilot program with CDC
• Objectives determine SIV incidence
  distribution, identify novel isolates, develop
  new diagnostic reagents, facilitate development
  of improved vaccines
• Surveillance pilot project plan developed by the
  National Surveillance Unit (NSU)
• novel strain detection in diagnostic laboratories
  
• concurrent human and swine infection public
  venues (e.g., fairs) pig herd SIV outbreaks
  linked to human flu infections
• Implementation 2009
