The unprecedented U.S. bird flu outbreak that is centered in Minnesota is likely to stick around for a few years and possibly damage poultry farms across the nation, a top U.S. veterinary official said Thursday.
"This is something very unusual, where we have seen bird flu adapt so well, " John Clifford, chief veterinary officer for the U.S. Department of Agriculture (USDA), told a Minnesota House agriculture committee.
The House voted unanimously late Thursday to pony up almost $900,000 to help state agencies battle the bug. For lost birds in Minnesota alone, the flu's tab is already in the tens of millions of dollars.
The USDA has already spent $15 million helping stricken farmers, and that's just the beginning.
The flu was confirmed Thursday on four more Minnesota turkey farms, bringing the total to 26, with more than 1.6 million birds affected. The disease also was reported at a commercial turkey farm with 126,000 birds in western Wisconsin's Barron County; and at a back yard flock of 40 birds in eastern Wisconsin.
Plus, another outbreak at a South Dakota turkey farm was disclosed, bringing the number in that state to four. Altogether, at least 12 states have been affected by the virus.
"It's something in North America that we may have to live with for a few years," Clifford told legislators. "It will very likely reoccur later this fall, and not just in Minnesota, but in all four flyways," he said, referring to major waterfowl migration routes across North America. "It can impact poultry across the United States."
The lethal H5N2 bird flu is believed to originate in waterfowl that don't get sick from the virus but spread it through their feces. Once it's in a waterfowl population, the virus can persist for three to five years, Carol Cardona, veterinary biosciences professor at the University of Minnesota, said at the hearing.
