Animal welfare is clearly a hot topic in the supermarket these days, as anyone can see just by taking a look at all the different types of labels and certifications that are meant to convince us that the animals we are eating led full, happy lives before they became dinner. The current list includes labels such as "free farmed," "certified humane," "cage free" and "free range," among others. Whole Foods is adding a new term to this group: animal compassionate.

"Animal compassionate" sets some of the following standards of care for animals: "Castration of sheep prohibited; electric prod on beef cattle permitted in emergencies; tail docking of pigs not allowed."

But in the end, these labels - many of which are developed by animal welfare groups or, as in this case, the stores that carry the products - are really just another security blanket for consumers who like the idea of an animal playing in a field and looking happy. It makes them feel good, like they're doing the right thing from the animal's perspective. It might also confuse consumers, many of whom already have difficulty choosing between organic, hormone/antibiotic free and grass fed animals.

For many shoppers, knowing that their food is organic is important. They don't like the idea of their food being treated with chemicals and other unknown substances before it reaches them. These same shoppers' interest in their food now extends all the way back to the farm - and not just for vegetables and fruits. The movement for seeing "certified humane" labeling on animal products is gaining popularity.

The label originated in 2003, when the nonprofit Humane Farm Animal Care (HFAC) developed a set of standards by which the quality of life and care for farm animals could be judged and designed a label to bring that standard of care to public attention. The USDA verifies the process. The "Certified Humane Raised & Handled" label means that a producer has passed inspection and certifies that their meat, poultry, egg and/or dairy animals are raised to humane care standards. Standards require that the animals have access to clean water and sufficient food and live in a comfortable environment, protected from the elements in inclement weather but with plenty of room to move and exercise naturally. Caretakers must also be trained in animal husbandry and welfare, and there is a prohibition on growth hormones and antibiotics.
