The most significant animal welfare law in recent history — California’s Prop 2 — takes effect today. The measure, which passed by a landslide vote in 2008, requires egg and some meat producers to confine their animals in far more humane conditions than they did before. No longer will baby calves (veal) or gestational pigs be kept in crates so small they cannot turn around and, perhaps more significantly, egg-laying hens may not be held in “battery” cages that prevent them from spreading their wings.
The regulations don’t affect only hens kept in California. In 2010, Gov. Arnold Schwarzenegger signed into law a bill that extended the protections of Prop 2 to out-of-state birds: You cannot sell an egg in California from a hen kept in extreme confinement anywhere. For an industry that has been able to do pretty much what it wants, this is a big deal: It bans some of the most egregious practices.
