New avian influenza strain takes flight

High-pathogenic avian influenza (HPAI) was diagnosed on Thursday in a flock of turkeys in Dubois County, Indiana.  (See map for the location of Dubois County).  The positive test result was from one barn of a reportedly 10-barn contract grower complex that is affiliated with Farbest Foods.  That farm was immediately de-populated and a 10 kilometer (roughly 6 mile) quarantine area was established. 

Here are the most recent developments:

  • The HPAI strain in this break is NOT THE SAME one that created so many problems for Midwestern turkey and egg producers last summer.  This strain, H7N8, has not been seen in the U.S. before.   The strain responsible for last year’s losses was H5N2.
  • Turkeys on ten more farms have tested positive but it appears that the H7N8 strain on these farms is not a high-pathogenic variety.  The original one from last week was characterized as high-pathogenic.   New 10 kilometer quarantine zones have been established around those farm and those zones reach into several neighboring counties.  One news report stated that just under 241,000 birds were on the affected farms and that about 120,000 have already been destroyed. 
  • One story characterized the area as “poultry-rich.”  In addition to turkeys, there are, according maps included in the 2012 Census of Agriculture, significant numbers of farms with broilers and layers in Daviess and Martin Counties, the two counties just north of Dubois County.  Quarantine areas stretch into those counties but infected birds have been found only in Dubois County. 
  • No human cases have been reported and health officials say the virus poses no food safety risk. 
  • For perspective, Indiana ranked fourth in turkey slaughter (Minnesota, Arkansas and Virginia were the top three) in 2014 but produced more pounds of turkey than any state except Minnesota.
  • Export customers will almost certainly move to ban imports from Indiana.  One report indicates that South Korea has already done so.  I expect to see more and those bans will apply to all poultry products from Indiana.

The poultry industry has been worried about a return of HPAI since the last case was reported back in mid-June.  The fear was that migrating wild birds would carry the virus from their summer grounds in Canada.   Most of last spring and summer’s trouble was in the Mississippi Flyway.  Indiana is on the eastern edge of that major pathway.  The biggest concern had been for the Atlantic Flyway which passes near or over several major poultry producing areas including the DelMarVa Peninsula, North Carolina and Georgia.  But that trouble hasn’t happened yet and many believe the mild fall weather may have delayed movement until recently.  

But it seems that is all a rather moot point given that this is a different strain of AI and that it has both low- and high-pathogenic varieties.  Regardless, this could mean trouble for poultry exports should it spread to other states.  That’s the bad news.  

The good news, though, is that it will reduce turkey supplies, pushing turkey prices upward once again.  And should HPAI come to major broiler areas, I still think the impact will be positive since leg quarter (our major chicken export item) prices are about as low as they can go and any loss of birds would restrict breast meat supplies, pushing prices higher for the close competitor for pork in retail meat cases.
