Further Two Avian Flu Outbreaks Confirmed in US

09 June 2015

US - Two more H5N2 highly pathogenic avian influenza outbreaks have been confirmed by the US Department of Agriculture's Animal and Plant Health Inspection Service.

The latest outbreaks are:

  • Minnesota, Brown county - 39,000 commercial turkeys;
  • Minnesota, Kandiyohi county - 44,000 commercial turkeys.

The total number of confirmed detections has now reached 219, with 46,824,393 birds affected.

Minnesota's share is at 103 detections, affecting 8,970,150 birds.

No new cases were confirmed in Iowa, but one probable case of the disease was announced in Sioux county yesterday.

Meanwhile, Michigan's state Department of Agriculture and Rural Development announced three cases of H5N2 avian flu in free-ranging geese, which are the first cases of the disease in the state.

Three goslings collected last week from Macomb County in the state were tested and found positive in several different labs.

Michigan is the 21st state to report a case of HPAI since December 2014. In the other 20 states, the virus has been found in captive wild birds or free-ranging birds, backyard flocks, and commercial flocks.

Michigan also becomes the 6th state to detect in wild or free-ranging birds only. 

“While this is disappointing news that the H5N2 virus has been found in Michigan’s free-ranging bird population, it was not unexpected given avian influenza has been found in a number of our neighboring states and Ontario,” said MDARD Director Jamie Clover Adams.

Ms Clover Adams stressed that avian influenza has not been identified in Michigan’s domestic poultry flocks.

“MDARD will continue to work hand-in-hand with our backyard and commercial poultry farmers to conduct surveillance testing and provide education along with Michigan State University’s Extension on implementing and stepping up on-farm biosecurity practices to protect the health of Michigan’s domestic poultry,” she said.

Keith Creagh, Michigan's Department for Natural Resources Director, said the state’s chief focus now is preventing the disease spreading in wildlife and its transmission to domestic poultry.

“This confirmed positive finding of highly pathogenic avian influenza prompts several steps that are informed by Michigan’s Surveillance and Response Plan for HPAI in free-ranging wildlife,” said Creagh. “The DNR and MDARD are working with other experts and taking advantage of every available resource to ensure a swift, appropriate response that limits the spread of HPAI.”

The state’s wildlife HPAI plan was developed by DNR’s Wildlife Division in 2006. The DNR already practices regular examination of carcasses from mortality events affecting birds and samples live-caught and hunter-harvested wild birds.
