McDonald’s announced yesterday that it will phase out gestation crates in its food supply chain. Gestation crates are essentially small cages pregnant sows spend their entire pregnancy, and sometimes lives, in. Whole Foods and Chipolte already buy pork from suppliers who raise pigs in a group environment versus the cages. And, I suspect McDonald’s move comes as a the Zeitgeist shifts even more as a result of Chipolte’s effective commercial/short film detailing the evils of big agra farming practices. People want to know that the cows, pigs, and chickens that they eat are being treated fairly. It’s odd to be sure–we are after all killing these animals as a food source–yet I’m more likely to buy free range chicken than not. Those Tyson chicken trucks going up 540 freak me out.
