ST. LOUIS (AP) — A legal battle over pet food ingredients has escalated with a new federal lawsuit against the United States' largest pet food maker.
The Blue Buffalo Company sued Nestle Purina PetCare Company Wednesday in U.S. District Court in St. Louis, where Purina is based. The suit comes barely one week after Nestle Purina lodged its own complaint over ingredients in the same court
Purina accuses its Wilton, Connecticut-based competitor of false advertising, disparagement and unjust enrichment. The counterclaim accuses Purina of some of the same deceits, as well as defamation.
Blue Buffalo advertises that its dog and cat food contain natural ingredients and do not contain chicken or poultry byproduct meals. The company's complaint calls Nestle Purina's criticisms part of a "nationwide advertising smear campaign."
