Make every mealtime an experience both you and your flock will love.Pursuant to an Order of the U.S. District Court for the Southern District of Ohio dated November 12, 2025, Purina hereby gives notice that it previously advertised Farm to Flock 18% Layer Hen Food as having a ‘built-in defense against avian influenza,’ ‘Defend[ing] Against Viruses, Like Bird Flu,’ and ‘helping defend against viruses like bird flu.’ At the preliminary injunction stage, the Court found that Purina engaged in false advertising because these statements were not scientifically grounded and lacked a scientific basis. Purina retracts these statements, as well as any other representation that Purina’s Farm to Flock 18% Layer Hen Food defends against, protects against, prevents, mitigates, or provides immunity to the effects of avian influenza, bird flu, or other viruses.
