 Over 60 major food companies have policies to eliminate their use.Smithfield Foods, the largest pork producer in the United States, said in January 2007 that it will phase out gestation crates from its 187 piggeries over the next ten years because of concerns from its customers.In 2009 the company stated it would no longer be able to phase them out in ten years due to recent low sales, but reversed the decision in 2011 after intense pressure from the Humane Society of the United States.
