In early December, the Humane Society of the United States released undercover video footage of downer pigs at an Iowa factory farm. In its newest campaign, Petition for the Pigs, Farm Sanctuary is petitioning President Obama to pass legislation to make it illegal for sick pigs to be slaughtered for consumption. Known for its tireless efforts to improve animal welfare, Farm Sanctuary has influenced similar milestone legislation in the past. Last spring, the group campaigned to eliminate downer cows from the food supply. In March, President Obama signed in a measure outlawing downer cattle. The organization currently has 10,000 signatures for the downer pig petition, with a target goal of 20,000.
