AFOs, CAFOs, and IFAP

n  EPA definition for animal feeding operation (AFO) -  Animals stabled/confined and fed/maintained for 45 days per

year -  Crops, vegetation, forage not sustained in normal growing

season over any portion of the lot or facility

n  Concentrated animal feeding operation (CAFO) -  >1,000 animal units = >1,000,000 pounds of live weight

n  Industrial food animal production—characterized by … -  High throughput production methods -  One site -  Controlled conditions -  Uniform consumer product -  Small profit margins

Localization of Production

n  1949 -  Poultry processing plants -  Each dot represents a plant

processing 50,000 or more chickens each year

n  2007 -  Chicken production -  Each dot represents annual

production of 1 million or more chickens

(USDA, 2009)

Vertical Integration/Contract Production

n  Structure extremely common (more than 90 percent) in poultry and swine industries (Martinez/USDA, 2002)

n  Integrators -  Own animals -  Control inputs -  Own processing plants

n  Growers -  Operate under contract -  Own animal waste

n  “Farmers”?
