All ingredients are sourced out of our Austin office and are fully traceable - we receive certificates of origin for each and every ingredient. All incoming ingredients are inspected when received at our USDA facility. Our facility is inspected on an ongoing basis by our team, USDA officials and other food safety organizations. Once finished product is produced, samples are sent to a third-party lab for independent testing for salmonella, e-coli, and listeria. We do not begin bagging the product until results have been received by the lab. You can see the results from our lab test for each finished bag of A Pup Above using our lot code feature on our product pages or on our food page.
