Do you ever wonder why so much organic food also carries animal welfare labels?

The short answer is that while the US Department of Agriculture's organic standards are very precise about pesticides and other growing practices for the crops that people and animals eat, it doesn't include very many specific instructions about the way the animals themselves are raised.

"When people pick up organic milk, they're expecting that the cows are out on pasture most of the time," says Luke Meerman, one of the farmers behind Michigan-based Grassfields Cheese. And he's right. In a phone survey conducted for the American Society for the Prevention of Cruelty to Animals (ASPCA), 68 percent of the consumers contacted said they expected that animals raised on organic farms "have access to outdoor pasture and fresh air throughout the day." Similarly, 67 percent said they believe "animals have significantly more space to move than on non-organic farms." Read more on Mother Jones.
