CAFOs concentrate thousands to hundreds of thousands of animals in confined spaces, creating welfare conditions that are the subject of the most significant ongoing welfare debates.
CAFOs represent the endpoint of industrial animal agriculture logic: maximum efficiency through maximum density. The welfare costs — chronic ammonia exposure, behavioral restriction, disease pressure, inability to perform natural behaviors — are systematic and unavoidable given the production model. CAFO workers themselves suffer significant health and welfare consequences from the environments they work in, creating a human-animal welfare alliance that is rarely exploited in advocacy. The welfare and environmental case against CAFOs converge in ways that offer policy leverage.
