As part of its 2001 guidelines, Burger King stated that it would begin conducting announced and unannounced inspections of the slaughterhouses for all of its meat suppliers and take action against facilities that fail those inspections. It would establish animal-handling verification guidelines for all the slaughterhouses of its suppliers. The company would require its suppliers to confine no more than five hens in each battery cage, that the birds be able to stand fully upright, and require the presence of two water drinkers per cage. It would stop purchasing from suppliers who engage in the forced molting of hens, develop auditing procedures for the handling of "broiler" chickens, and institute humane handling procedures for chickens at slaughterhouses. It would begin purchasing pork from farms that do not confine sows to stalls.
