Concentrated Animal Feeding Operations (CAFO)
What is a CAFO?
An operation must first be defined as an Animal Feeding Operation (AFO) before it can be considered a Concentrated Animal Feeding Operation (CAFO). AFOs are agricultural operations where animals are kept and raised in confined situations.
EPA defines an AFO as 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.
