I might be wrong, but, I think here in the United States, there is no specific definition for "free-range" beef. All United States Department of Agriculture (USDA) definitions of "free-range" refer specifically to poultry. No other criteria, such as the size of the range or the amount of space given to each animal, are required before beef can be called "free-range". Claims and labeling using "free range" are therefore unregulated. The USDA relies "upon producer testimonials to support the accuracy of these claims."
