Researchers discover Senecavirus A and PRRSV in flies at hog farms

A preliminary study ties swine viruses in infected hog farms to flies. Researchers trapped flies from Senecavirus A and porcine reproductive and respiratory syndrome virus positive farms (PRRSV). Laboratory testing confirmed one out of six traps were PCR positive for PRRSV, and two of six traps were PCR positive for Senecavirus A.

This finding presents a new risk for the swine industry to consider; are flies a potential risk factor in the transmission of Senecavirus A?

Animal and Plant Health Inspection Service revises chronic wasting disease program standards

The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) is revising its Chronic Wasting Disease (CWD) Program Standards to better meet the needs of both animal health officials and the cervid industry.

The CWD Herd Certification Program provides a national approach to control CWD in farmed cervids. The program is a cooperative effort between APHIS, State animal health and wildlife agencies, and farmed cervid owners. APHIS coordinates with State agencies to encourage cervid owners to certify their herds and comply with the CWD Herd Certification Program Standards to prevent the introduction and spread of CWD.

The revisions cover a variety of topics including:

  • Adding guidelines for live animal testing in specific situations (applies only to white-tailed deer).
  • Clarifying how disease investigations should be handled, aligning with the Code of Federal Regulations’ requirement for mortality testing.
  • Simplifying fencing requirements.
  • Adding biosecurity recommendations.
  • Describing the intended approach to update the CWD-susceptible species list.

APHIS also outlines factors for determining indemnity and includes a table that outlines possible reductions in herd certification status that States may consider for herd owners that do not submit required mortality surveillance samples or consistently submit unusable testing samples.

Invitation to participate in the Secure Pork Supply Plan

The Minnesota Board of Animal is preparing to participate in a multi-state functional exercise to prepare for the possibility of a widespread Foreign Animal Disease outbreak. The Board recently hired Dr. Dave Wright to assist producers and veterinarians in the participation process. He is available to walk you through the plan at no charge, and we encourage you to take advantage of his expertise.

From Dr. Dave Wright, 

I recently attended a Webinar reviewing a mock exercise to prepare us for a multi-state Foreign Animal Disease outbreak. It became apparent that if this should occur, participation in the Secure Pork Supply plan will no longer be voluntary; it will be mandatory in order to obtain a permit to move pigs. Details on the plan are available at www.securepork.org.

I have met with several producers and systems to facilitate participation and have outlined a step-by-step approach to make the process more manageable. The Board of Animal Health has hired me to assist in the participation process at no charge to you, so I encourage you to take advantage of the free service. Contact me at wright2me.dave@gmail.com or 763-242-7535 to arrange a visit.

Written statements may be filed at the meeting or filed with the Committee before or after the meeting by contacting Dr. Denise Heard at Denise.L.Heard@aphis.usda.gov.

At the General Session of the Biennial Conference, State Delegates representing the poultry industry, will discuss and debate the adoption of Proposed Changes to the NPIP Provisions and Program Standards. Some of the proposals that will be discussed include:

  • Approval of new diagnostic tests.
  • Amending Avian Influenza program requirements and test standards.
  • Amending Salmonella Classifications.
  • Proposing and revising new Sanitation standards for flockowners, hatcheries and dealers.
  • Proposing new tests and classifications for Newcastle Disease.

A complete listing of the proposals to be considered can be found on the NPIP website, www.poultryimprovement.org APHIS is also proposing updates to its NPIP regulations, as voted on and approved at the 2016 biennial conference. The changes would update and clarify several provisions, including those concerning NPIP participation, voting requirements, testing procedures, and standards. Full text of the updates will be available after Federal Register publication.

Minnesota re-certified "Pseudorabies Free"

State pseudorabies status is important for interstate movements and offers state and federal animal health officials a known standard of Minnesota's swine health status.  Additionally, the state status provides important information on swine surveillance.

USDA's Veterinary Services Surveillance, Preparedness, and Response Services unit reassigns Stage V State-Federal-Industry Pseudorabies Eradication Program status to Minnesota for a 1-year period.
