Even though Congress pulled federal funding to inspect horse meat destined for consumption in the U.S. in 2007, 68,444 tonnes of horse meat were produced in the country in 2010, according to the FAO. In 2011, Congress lifted the ban on funding horse meat inspections.
According to the U.S. Government Accountability Office:
Since fiscal year 2006, Congress has annually prohibited the use of federal funds to inspect horses destined for food, effectively prohibiting domestic slaughter.
Since domestic horse slaughter ceased in 2007, the slaughter horse market has shifted to Canada and Mexico. From 2006 through 2010, U.S. horse exports for slaughter increased by 148 and 660 per cent to Canada and Mexico, respectively.
