In 2010, the Humane Society of the United States filed a lawsuit against Perdue for violating a New Jersey consumer fraud law by applying the labels "purely all-natural" and "humanely raised" to its products when reasonable consumers would not consider the conditions Perdue chickens are raised in “humane.” The Humane Society filed a similar lawsuit in Florida in April 2013 after an appeal by Perdue to have a similar case rejected was turned down by a federal court.
The Humane Society of the United States has been challenging Perdue's use of certain product labels, arguing they are misleading consumers regarding the treatment of chickens. This issue was first addressed in 2010 in New Jersey and again in April 2013 in Florida after an appeal by Perdue.
