To earn the trust of pet lovers, we have to be transparent. Below you will find a list of topics which should address some of your questions. If you are unable to find the information you are looking for, please get in touch with us using one of the contact methods found on this website.

In 2018, the FDA first reported a potential association between canine dilated cardiomyopathy (DCM) and diet. The FDA has never recommended that Pet Lovers change their pets’ foods and did not request any recalls from pet food manufacturers. To date, review of available scientific literature and research on DCM has found there is no definitive, scientific link between DCM and our foods or grain-free diets. Currently, researchers attribute many factors as possible causes for DCM in dogs, including genetics, breeding and lifestyle. Unfortunately, this is an issue that has been sensationalized by many in the industry who stood to gain from calling into question grain-free foods and by the media looking for eye-catching headlines. Tens of millions of Pet Lovers continue to feed their dogs a grain-free diet, including the food we make, and animals thrive on them. We remain steadfast when it comes to the safety of our food. As the FDA continues to investigate any connection between DCM and diet, Champion is working with the agency’s scientists, the pet food industry, our in-house experts and independent researchers to advance our broader understanding of DCM, identify its cause and risk factors for the condition. The goal of this research is to ensure Pet Lovers feel confident in the premium nutrition choices they are making. We continue to test out food every day to ensure we are meeting all quality and safety standards and to deliver the best possible nutrition for pets. This article, appearing in the journal of Animal Science, provides an overview of the scientific literature on the issue.
At Diamond Pet Foods, nothing is more important to us than the safety of our products. We adhere to stringent and scientifically advanced food safety protocols. We constantly monitor and test our raw materials, production environment, processes and finished products. By implementing scientific and technological advancements, we have developed a comprehensive food safety system.


We test and monitor every aspect of the manufacturing process: pre-production, production and post-production.
  • 1,340 Mycotoxin Tests/week
  • 1,600+ Microbiological Tests/week
  • 225 Oxidative Stability Tests on Fats & Oils/month
  • 7,500+ Ingredient Nutritional Tests/month
  • 56,000+ Finished Product Nutritional Tests/month
  • 18+ Hours of Employee Safety Training per Employee/year
  • 600+ Safety Assessments/year


No grain ingredients, which could be at risk for mycotoxins, are allowed to enter our facilities without having been thoroughly analyzed, using advanced testing methods and equipment. Mycotoxins are toxic chemicals produced by fungi that can appear in grains. At Diamond, we perform 1,340 mycotoxin tests every week. An extra layer of protection is added by testing all finished products containing corn or rice on an hourly basis prior to release.


We conduct over 1,600 microbiological tests every week, including finished product tests, in-process tests, environmental tests and sanitation-verification tests. All topical palatants and probiotics must have a Certificate of Analysis and prove to be Salmonella negative before submission to Diamond Pet Foods. We also perform approximately 225 oxidative stability tests every month for all fats and oils used as topical ingredients.


We utilize a water purification process to ensure the water we use is free from microorganisms and organic and inorganic chemicals. Using a process known as reverse osmosis, water is forced through a series of fine filters to remove any possible contaminants.


All of our manufacturing facilities are segregated into zones to ensure separation of raw materials from finished products. Each production area is equipped with HEPA®-filtered and ozone air-treated handling units to ensure clean, treated air is utilized in each of the segregated zones.


No product is released into distribution without adhering to the strict standards of our Test and Hold Program, in which product tests are conducted by a certified, independent laboratory. We use scientifically- and statistically-based referencing standards set by the ICMSF (International Commission on the Microbiological Specification for Foods). Samples are collected and tested for every product produced. Every sample is kept for a time equal to the guaranteed shelf life of the product, typically 12 months. And no product is released without this verification activity.
