How humane is dead?
The point is: ask. Know where your meal comes from despite what the menu, newspaper review, or grocery store billboard says. More and more restaurants and retailers are going to want to cash in on the growing sustainable food movement, so chances are this kind of mislabeling will grow with it.
This sort of "concern" among foodies regarding terms like "free-range" vs "free-roam" is how they can cash in on the "growing sustainable food movement." Eating meat is not sustainable. Fully a third of the world's fossil fuel production goes towards animal production. So how do you get around this? Talk about things like "humane slaughter" and "factory farms" when in the end, you're still guilty of the ultimate cruelty, no matter how many days the chicken spent "on the outside."
