LUBBOCK, Texas (AP) - Animal advocates want improvements made at a West Texas feedlot where they say live horses are feeding in pens as carcasses decompose nearby.
Critics say some horses eat hay from atop compost piles.
State environmental investigators have not been able to verify the allegations in four trips to the Frontier Meat -- near Morton -- in the past year.
Terry Clawson with the Texas Commission on Environmental Quality say all of the trips have been without warnings or notification.
The operation, which feeds horses and buffalo, is owned by Fort Worth-based Beltex.
The company has been cited for failure to have permit to operate and failure to have solid waste storage permit, which pertains to the carcasses not being composted correctly.
Calls seeking comment from Beltex and Frontier Meat weren't immediately returned.
The most recent complaint was filed Wednesday.
