The Pew Commission on Industrial Farm Animal Production and the National Conference of State Legislatures have released a report on state policies governing large feedlots, also know as concentrated animal feeding operations, or CAFOs.

The state survey is part of a 2 1/2 year study of industrial farm animal production and its effect on public health, the environment and animal welfare.

The study said that California "appears to be working diligently to curb any runoff from CAFOs into water sources."
