The cases were filed by individual consumers in New Jersey and Florida, in 2010 and 2013, in response to labels that stated the products were "humanely raised", which they claimed was misleading.
The terms of the settlement required the plaintiffs to dismiss their claims with prejudice, in exchange for Perdue agreeing to remove the "Humanely Raised" label claim from its Harvestland chicken packaging.
Peter Petersan, director of Animal Protection Litigation for the HSUS, said he was pleased to see the claim removed from the packaging.
Herb Frerichs, general counsel for Perdue Farms, said: "Perdue rejects the plaintiffs’ allegations and maintains that its labels are not misleading in any way. Nonetheless, it has agreed to discontinue the labelling claim at issue."
