Bird flu ebbing, dangers still there, experts warn

OMAHA, Neb. — A bird flu outbreak in the U.S. 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 happen 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.”

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. 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 U.S. 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.

Economists expect egg and meat prices to ease this summer as farms are able build back their flocks.

“I think that there is going to start being some relief,” said Jada Thompson, an agricultural economist at the University of Arkansas.
