DAKOTA DUNES, S.D. — Open Prairie Natural Angus Beef, a premium-quality, natural Angus beef line from Tyson Fresh Meats Inc., a subsidiary of Tyson Foods Inc., is now available throughout the U.S.

This line exceeds the U.S.D.A. criteria established for natural meat designation, according to Tyson. It is audited by an independent verification system at ranch level on essential criteria, including no added hormones or antibiotics, no artificial ingredients, and no animal by-products fed — 100% vegetarian diet.

“We identified ranchers with a strong commitment to the environment and to raising cattle naturally on grass and grain without added hormones or antibiotics when developing this brand,” said Kent Harrison, senior director of marketing and value creation for Tyson Fresh Meats. “We also conducted extensive consumer research to understand the values and messages that resonate best with natural consumers across the U.S.”

“The natural standards we uphold are an extremely important aspect of what we do,” said Thad York of Silver Spur Ranch, one of the ranchers supplying Tyson Fresh Meats with cattle for the new brand. “Our focus is to keep things as natural as possible.”

“This brand was created to bring consumers closer to the phenomenal work that these ranchers are doing to raise cattle naturally and to provide our customers with a consistent, high-quality natural Angus brand they can depend on,” Mr. Harrison added.
