The taboo surrounding horse meat in the United States received national attention again in May 2017 when a restaurant in the [[Lawrenceville (Pittsburgh)|Lawrenceville]] section of [[Pittsburgh]] served a dish containing [[Steak tartare|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 [[United States Department of Agriculture|USDA]] not to serve horse meat again. A [[Change.org]] petition subsequently went up to advocate making serving horse meat illegal in Pennsylvania.<ref>{{Cite web|url = http://pittsburgh.cbslocal.com/2017/05/15/usda-warns-pittsburgh-restaurant-that-served-horse-meat/|title = USDA Warns Pittsburgh Restaurant That Served Horse Meat|date = May 15, 2017|access-date = May 20, 2017|archive-date = May 18, 2017|archive-url = https://web.archive.org/web/20170518211537/http://pittsburgh.cbslocal.com/2017/05/15/usda-warns-pittsburgh-restaurant-that-served-horse-meat/|url-status = live}}</ref>
