Free range is a term which denotes a method of farming husbandry where the animals can roam freely for food, rather than being confined in an enclosure. On many farms, the outdoors ranging area is fenced, thereby technically making this an enclosure, however, free range systems usually offer the opportunity for extensive locomotion and sunlight prevented by indoor housing systems.
The USDA label laws describe FREE RANGE or FREE ROAMING:
Producers must demonstrate to the Agency that the poultry has been allowed access to the outside.
The USDA has no specific definition for "free-range" beef, pork, and other non-poultry products. All 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, lamb, and pork 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."
