Birds from nine more commercial turkey farms in Indiana have tested positive for bird flu.
The nine are located near a farm that authorities previously announced had been infected. The Indiana State Board of Animal Health says testing is underway to determine the strain of the highly-contagious virus.
Authorities confirmed Friday that a commercial flock in Dubois County Indiana was infected with the H7N8 strain, which is different than the H5N2 virus that led to the deaths of about 48 million turkeys and chickens last summer.
Denise Derrer, spokeswoman for the Indiana board, said officials are still trying to determine how many birds are affected on the nine farms covered by the announcement Saturday. All 60,000 turkeys on the first farm have been euthanized.
