IT’S A sign of progress in the food industry when good ethics are seen as good business. Last week, McDonalds announced that it would require its pork suppliers to phase out the use of “gestation pens,’’ the 2-foot-by-7-foot metal cages that some industrial farms use to hold breeding sows.
Animal-rights advocates, including the Humane Society of the United States, have long complained that the pens are unsanitary and cruel. The European Union, New Zealand, and eight US states have already banned their use. A move from a giant restaurant chain will pressure the agriculture industry even more: McDonalds buys 1 percent of the US pork supply to make its Sausage McMuffins, breakfast platters, and McRib sandwiches.
