Every pet deserves the very best

That’s the idea that started it all back in 1970. Was it possible to produce high-quality, premium pet food at a price the average pet owner could afford?  Fortunately, the answer was “yes.” And today, Diamond Pet Foods is one of the fastest growing manufacturers of pet foods in the country, with brands trusted by professional breeders, trainers, veterinarians and nutrition-conscious pet owners in more than 100 countries worldwide.

We’re a family-owned company with strong Midwestern values. And staying true to that original vision of making premium pet food affordable has never been compromised by outside, corporate thinking. Maybe that’s how we’ve managed to do it. Whatever the case, we’re not about to change now. Every pet does deserve the very best.

And that includes yours.

Our History

Diamond Pet Foods began in 1970 with a shared vision. Our founders, brothers-in-law Gary Schell and Richard Kampeter, believed that premium pet food could be produced at an affordable price. Together, they purchased a former milling company in the town of Meta, Missouri (population 220), and the Diamond company was born.

Soon, nutrition-conscious pet owners were validating Gary and Richard’s theory and buying Diamond Pet Foods products. Our plant in Meta was modernized with state-of-the-art equipment, and we expanded our production capacity in order to meet the growing demand with plants in Lathrop, California in 1999; Gaston, South Carolina in 2003; and Ripon, California in 2012.

Today, Diamond Pet Foods remains one of the fastest growing pet food manufacturers in the country. Our products are trusted by professional breeders, trainers, veterinarians and pet owners in all 50 states and in 100 countries around the world. The second generation of Schell and Kampeter families still own and operate the company. And we still believe that every pet is worthy of the best nutrition. Including yours.

About Diamond Pet Foods

Diamond Pet Foods has always been a family owned and privately held company. We also happen to be one of the leading manufacturers of pet food in the nation, with a complete range of proprietary and private label products that we manufacture in four, state-of-the-art and safety-certified facilities across the country.

We’re committed to constantly developing new and innovative products and processes to ensure your pet is getting the very best nutrition possible. This includes a commitment to product safety that has led to one of the most comprehensive food safety programs in the industry.

Our Philosophy

Our philosophy and our business model have always been to produce premium pet food at an affordable price. Because we believe every pet, from purebred show animal to shelter puppy or kitten, is worthy of the best nutrition.

In order to provide the highest quality ingredients and products at an affordable price, we’ve developed unique relationships with our suppliers. Being privately held, we can look beyond short-term, quarterly shareholder results and enter into long-term agreements with our vendors. These long-term arrangements with our vendor-partners have led to preferred pricing, vendor loyalty, and a steady supply of quality ingredients for Diamond.

The Diamond Family of Brands

We offer a variety of premium pet food brands to meet the needs and taste preferences of all life stages, lifestyles and levels of activity.

Nutritional Testing

To ensure all of our pet foods meet or exceed nutritional standards, we conduct nutritional testing on both ingredients and finished product. Over 1,500 tests are conducted on ingredients every week, and over 11,000 tests per week are conducted on finished product. Our ingredient suppliers also employ a variety of methods to ensure nutritional standards prior to shipment.

Scientific Formulations

Our pet food formulas are based on the latest animal nutrition research and are carefully designed to meet your pet’s specific life stage. No matter which formula you choose, you can rest assured you’re getting the very best nutrition for a long and healthy life. Here are some of the benefits you’ll find in select Diamond formulas:

  • Real meat for great taste and highly digestible protein
  • Fruits and vegetables provide natural antioxidants for a healthy immune system
  • Properly balanced omega-3 and omega-6 for healthy skin and coat, and reduced inflammation of skin, joints and digestive system
  • Proper fat ratios for sustained energy levels
  • Glucosamine and chondroitin for healthier joints and cartilage

Supplier Management Program

Our ingredients suppliers are approved through a rigorous process intended to validate commitments to food safety and ingredient quality, and also to ensure financial viability. Our method is to work with fewer suppliers under longer-term arrangements, rather than engage with a host of suppliers participating in a continual bid process. This approach fosters trust, collaboration, and continual improvement, and works to encourage vendor-partners to make investments in quality control, food safety training, and laboratory testing equipment.

The Highest Quality Ingredients

When we made the conscious decision to only make pet food you’d be proud to feed your own pet, we didn’t skimp on quality. That’s why we source the finest ingredients and establish solid relationships with our trusted suppliers to ensure we’re always getting the very best. All of our formulas are unique, based on your pet’s needs and life stage, but here are just a few of the quality ingredients you’ll find in our products.

  • Fresh chicken, real lamb, salmon, turkey, fowl, bison and venison
  • Vegetables like carrots, peas, sweet potatoes, spinach
  • Fruits like apples, blueberries, cranberries
  • Whole grains such as brown rice, barley and oatmeal
  • Prebiotics and probiotics for healthier digestion

How We Ensure Every Pet is Getting the Very Best

At Diamond, we only make products that we’d be proud to feed to our own pets. We start with the highest quality ingredients, including real meat and natural fruits and vegetables. Then our veterinarians and nutritionists carefully develop formulas that meet all dietary nutritional standards. Every product is precision formulated for content, quality, consistency and uniformity. And finally every one of our products undergoes a rigorous quality-control process to ensure it meets the highest levels of quality and safety.

A Commitment to Food Safety

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 continuously improving performance with the latest advancements in science and technology, we’ve developed a comprehensive food safety system.

On-site Product Testing

We test and monitor every aspect of the manufacturing process: pre-production, production and post-production.

1,075 Mycotoxin Tests/week
1,300+ Microbiological Tests/week
180 Oxidative Stability Tests on Fats & Oils/month
6,000+ Ingredient Nutritional Tests/month
45,000+ Finished Product Nutritional Tests/month
18+ hours of Employee Safety Training per employee/year
600+ Safety Assessments/year

Mycotoxin Control

No grain ingredients, which could be at risk for mycotoxins, are allowed to enter our facilities without having been thoroughly analyzed, using the most advanced testing methods and equipment available. Mycotoxins are toxic chemicals produced by fungi that can appear in grains. At Diamond, we perform 1,075 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.

Microbial Testing

We conduct over 1,300 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 180 oxidative stability tests every month for all fats and oils used as topical ingredients.

Water Quality

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.

Air Quality

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.

Test and Hold Program

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.

State-of-the-Art Facilities

Diamond Pet Foods is produced at four state-of-the-art manufacturing facilities across the U.S. In addition to our headquarters in Meta, Missouri, we have plants in Gaston, South Carolina; Lathrop, California; and our newest plant is in Ripon, California. All facilities incorporate the latest technology and manufacturing processes. Every step of the process is carefully monitored, tracked and measured to ensure the quality and safety of every product we make.

Every Diamond Pet Foods facility undergoes a yearly Good Manufacturing Practices (GMP) audit administered by NSF International®, an industry-leading food safety audit firm, headquartered in Ann Arbor, Michigan. Good Manufacturing Practices are guidelines that ensure the product being produced has the “identity, strength, composition, quality, and purity that it is represented to possess.”
