OMAHA, Neb. – A bird flu outbreak in the US that led to the deaths of more than 40 million chickens and turkeys and contributed to a spike in egg and meat prices appears to be waning, but experts caution the virus hasn´t disappeared and worry another surge could take hold this fall.
The number of birds culled to limit its spread dropped from a peak of almost 21 million in March to less than 800,000 in May.
However, more than 2 million birds have been killed already this month after infections were discovered at two large farms in Colorado.
“The numbers in the dashboard do tell a story, but we are not ready to say the outbreak is winding down,” said Richard Coker, a spokesman for the Animal and Plant Health Inspection Service division of the Department of Agriculture.
“We remain vigilant and encourage producers to continue to practice strong biosecurity,” Richard added according to AP.
Some state and industry officials are optimistic that the outbreak is ending, although no one is quite ready to relax.
Iowa Agriculture Secretary Mike Naig said the virus still poses a risk because more cases are being reported, but that “it really does feel like we´re on the tail end of it for this year.”
When a case of the highly pathogenic virus is found, officials kill the entire flock to limit its spread. The virus doesn´t discriminate between backyard flocks and massive egg farms; flocks of all sizes have been infected.
Iowa, the nation´s leader in egg production, was by far the hardest hit state with 13.4 million birds lost. No cases have been reported in the state since May 4, likely because migrating wild birds, which are blamed for spreading the virus, have moved out of Iowa.
Nebraska lost nearly 4.9 million birds, Pennsylvania lost 4.2 million and Colorado saw 3.6 million birds killed. Minnesota and Wisconsin each lost about 3 million.
An outbreak in 2015, when 50 million turkeys and chickens were killed, remains the most expensive animal health disaster in US history.
The government spent nearly $1 billion then to deal with infected birds, clean up barns and compensate farmers. The USDA has so far approved $793 million to cover costs this year.
