JEFFERSON CITY, Mo. (AP) — Missouri agriculture officials say nearly 9,000 laying hens were killed after confirmed cases of bird flu were found on a farm in Webster County. The Missouri Department of Agriculture said in a news release that it is the 11th case of bird flu found in the state this year. Agriculture officials say the disease does not carry a health risk for humans. State and federal officials are conducting additional surveillance and testing in the areas around the affected flock.
