With a fifth consecutive perfect Good Manufacturing Practices Plus (GMP+) audit, Diamond V is setting an industry standard for high-quality manufacturing and facilities operation.

GMP+ certification verifies that Diamond V has in place proper manufacturing practices and has implemented an effective Hazard Analysis Critical Control Point (HACCP) food safety program. The GMP+ certification audit, performed by SGS Services, scores each company on ten categories: Hazard Analysis, General Hygiene Requirements, Training, Interior Facility Cleanliness, Exterior Facility Cleanliness, Material Receiving, Storage and/or Processing, Product Loading, Pest Control, and Recall Program.


“Perfect scores are very rare, and we feel fortunate to have received a perfect score on each of our five audits. This certainly could not be achieved without the efforts of everyone in our facility,” said Mike Goble, Vice President of Operations.

Diamond V Mills is the world’s leading manufacturer and marketer of fermentation products used to optimize the palatability and digestibility of feeds for all types of animals. These products, manufactured at its headquarters in Cedar Rapids, Iowa, are used in feeds for dairy, swine, beef, horses, poultry, pets, and aquaculture.
