“[The] plaintiffs’ only purported basis for economic injury stems from their allegation that the Baby Food Products posed a threat of future harm—an allegation that Plaintiffs explicitly disavow in the context of personal injury … Plaintiffs fail to allege sufficient facts to support a finding of economic injury for the same reasons they cannot support a personal injury claim: there is no ‘actual or imminent’ injury alleged,” Judge Michael S. Nachmanoff wrote, dismissing the case.
