Senate, were introduced in the 109th Congress to prevent the slaughter of horses for human consumption. H.R. 503 was passed by the House on September 7, 2006, by a recorded vote of 263–146. S. 1915 was read twice, referred to committee and not voted on. Both bills died at the end of the 109th Congress, and were reintroduced in the 110th Congress on January 17, 2007, as H.R. 503 and S. 311. S. 311 was reported out but not taken up for a vote. The bills were not reintroduced in the 111th Congress. Two bills were introduced in the 112th Congress: H.R. 2966 and S. 1176, the American Horse Slaughter Prevention Act of 2011. The latter was introduced on July 9, 2011, by Senators Mary Landrieu (D-LA) and Lindsey Graham (R-SC) to amend the Horse Protection Act of 1970 () to prohibit the shipping, transporting, moving, delivering, receiving, possessing, purchasing, selling, or donation of horses and other equines to be slaughtered for human consumption. A new iteration of the SAFE Act was introduced in 2021 as H.R. 3355 to the U.S. House of Representatives on February 19, 2021, by Rep. Janice Schakowsky (D-IL) but as of this date has not been brought to the floor for a vote Transport of horses for slaughter Although the Department of Transportation has officers at enforcement points to ensure the proper transportation of horses, it has no jurisdiction beyond transportation. Horses that "are severely lame or disabled are not accepted at the plants". A 1998 USDA Animal and Plant Health Inspection Service survey to determine welfare problems during equine transport to slaughter found severe problems in 7.7 percent of the transported horses; most arose from owner neglect or abuse, rather than transportation. The report recommended fining individuals who transport horses unfit for travel. However, despite those recommendations, in an April 2011 report on equine transport violations, of 458 violators and 280 cases reported since February 1, 2002, 51 violators were fined a total of $781,350. The highest fines imposed were $230,000.00 on Charles Carter of Colorado, $162,000 on Leroy Baker of Ohio and $77,825 on Bill Richardson of Texas. A 2007–2015 investigation by Animals' Angels found overcrowded pens, aggression, rough handling, transport with no rest, untreated injuries and no water or food for more than the 28 hours required by law. On February 22, 2007, Representative Robert Molaro introduced HB1711 to the Illinois General
