A Concentrated Animal Feeding Operation (or CAFO) is a livestock facility in which animals are kept and raised in a confined area for agricultural reasons (namely meat, dairy, and eggs).

According to the Environment Protection Agency, a CAFO is "is a lot or facility (other than an aquatic animal production facility) where the following conditions are met:

  • animals have been, are, or will be stabled or confined and fed or maintained for a total of 45 days or more in any 12-month period, and

  • crops, vegetation, forage growth, or post-harvest residues are not sustained in the normal growing season over any portion of the lot or facility."

CASFER works closely with CAFOs as a potential source for sludge.
