June 20, 2009: A concerned pet owner provided pfpsa.org with funds and a variety of unrecalled dry cat food samples, which we received in ziplock bags, to have tested through the Washington Animal Disease Diagnostic Lab. Toxicology testing is done through WADDL by the Analytical Sciences Laboratory University of Idaho. We tested 5 samples believed to be three each of Nutro, one Wellness and one Purina. The tests show two of the three Nutro samples contained zinc at levels that would be illegal for sale in the European Union, at 270 ppm and 380 ppm. The third Nutro sample came in at 230 ppm. Purina and Wellness both came in at 190 ppm, which is still 40 ppm higher than the European Union’s recommended maximum of 150 ppm. The huge variation in Nutro results suggests very poor consistency and quality control. From one bag to the next, it’s about like playing Russian Roulette. It’s important to keep in mind pet food is typically the only thing our pets eat, day in and day out, month after month, year after year. Chronic exposure to over supplemented food, especially metals, hasn’t been studied enough to justify over supplementation as an industry standard.
