The FDA reported that Nestlé Purina PetCare Company expanded its voluntary recall of Purina Pro Plan Veterinary Diets EL Elemental (PPVD EL) prescription dry dog food. The recall is due to a supplier error resulting in potentially elevated levels of vitamin D in two additional product lots, which precede the production dates of the previously recalled lots. The expansion results from an investigation prompted by Purina that uncovered new information about a production error from a U.S. supplier. Only this specific formula resulted in potentially elevated levels of vitamin D. The recalled lots are Purina Pro Plan Veterinary Diets EL Elemental (PPVD EL)8 lb and 20 lb bags. The affected dry dog food was distributed throughout the United States by prescription only through veterinary clinics, Purina Vet Direct, Purina for Professionals, and other select retailers with the ability to validate a prescription.
