restriction was temporarily removed in 2011 as part of the Consolidated and Further Continuing Appropriations Act for Fiscal Year 2012 but was again included in the FY2014 Agriculture Appropriations Act and subsequent federal budgets, hence preventing the operation of any domestic horse slaughter operation. Until 2007, only three horse meat slaughterhouses still existed in the United States for export to foreign markets, but they were closed by court orders resulting from the upholding of aforementioned Illinois and Texas statutes banning horse slaughter and the sale of horse meat. The taboo surrounding horse meat in the United States received national attention again in May 2017 when a restaurant in the Lawrenceville section of Pittsburgh served a dish containing horse tartare as part of a special event the restaurant was hosting with French Canadian chefs as guests. The restaurant, which otherwise does not serve horse meat (which is legal to serve and consume in Pennsylvania), received an inspection and a warning from the USDA not to serve horse meat again.
