Horse Slaughter Prevention Bills and Issues

Source: Crs


In 2006 two Texas plants and one in Illinois slaughtered nearly 105,000 horses for human food, mainly for European and Asian consumers. The 109th Congress voted to limit the use of FY2006 appropriated funds for such slaughter, but it continued, funded by industry user fees. In 2007, court action effectively closed the Texas plants, and a new state ban in Illinois closed its plant. Debate revolves around the acceptability of horse slaughter, and how to care for and/or humanely dispose of horses if they no longer went for human food. In the 110th Congress, the Consolidated Appropriations Act, 2008 (H.R. 2764) bans appropriated funds and user fees for inspection of horses for human food. Pending H.R. 503 and S. 311 also would ban horse slaughter.


Nearly 105,000 horses were slaughtered for human food in 2006, all in two Texas plants and a third in Illinois, according to the U.S. Department of Agriculture (USDA). Virtually all was for export; the largest markets were France, Belgium, Switzerland, Italy, Japan, and Mexico. The United States exported more than 17,000 metric tons of horse meat valued at about $65 million in 2006. Most of these horses are raised for other purposes, like riding, but are no longer wanted by owners. Dealers collect them for the foreign-owned plants from auctions, boarding facilities, and elsewhere. Although U.S. horse slaughter had been rising since 2002, it remained below levels of the 1980s, when more than 300,000 were processed annually in at least 16 federally inspected plants.

The U.N. Food and Agriculture Organization estimates that Canada and Mexico respectively slaughtered a total of 88,000 and 626,000 head for horsemeat in 2005; a portion of these were shipped from the United States. (According to USDA, the United States in 2005 exported more than 21,000 live horses to Canada and more than 11,000 to Mexico. Many are believed to have been destined for slaughter for food.)

Legal Authorities

Federal Law

Federal laws neither ban the use of equines for food nor set on-farm care standards. Protection usually is subject to varying state and local laws. Some of these laws may set care standards, although more are likely to be anti-cruelty measures. However, U.S. horse slaughter plants were long subject to the Federal Meat Inspection Act (FMIA) of 1906, as amended (21 U.S.C. 601 et seq.), which requires USDA to inspect all cattle, sheep, swine, goats, and equines slaughtered and processed into products for human food. This act, administered by USDA’s Food Safety and Inspection Service (FSIS), aims to ensure that meat and meat products from these animals are safe, wholesome, and properly labeled. FSIS safety inspection is mandatory, and most costs must be covered by appropriated funds, except for overtime and holiday periods. Meat inspectors also are charged with enforcing the Humane Slaughter Act (7 U.S.C. 1901 et seq.), requiring that livestock (but not poultry) be rendered unconscious prior to slaughter.

Plants also can request that graders from USDA’s Agricultural Marketing Service (AMS) be placed in their plants to assign official grades to their products based on quality traits and yield. Plants pay user fees for this inspection service, which is voluntary and conducted under authority of the Agricultural Marketing Act (AMA) of 1946 as amended (7 U.S.C. §§1621 et seq.). The 1946 AMA is also the authority FSIS uses to provide voluntary food safety inspections of animals and products not specifically covered by either the Federal Meat Inspection Act or the Poultry Products Inspection Act.

Horses often had to be shipped long distances to reach the few plants that, until 2007, were slaughtering them. Horse practitioners and welfare groups gained passage of language in the 1996 farm bill (P.L. 104-127, Title IX-A, Commercial Transportation of Equine for Slaughter, 7 U.S.C. note) that authorizes the Secretary of Agriculture to issue guidelines for regulating such transport, subject to available appropriations. USDA’s Animal and Plant Health Inspection Service (APHIS) developed the guidelines with the cooperation of horse groups, and they became effective February 5, 2002.1

Legal Developments

Several states — including Texas — have laws aimed at preventing the slaughter of horses for human food. A federal lawsuit filed by the owners of the two Texas slaughter plants, Beltex Corporation and Dallas Crown, Inc., sought to clarify that the Texas state law banning the sale of horsemeat, first passed in 1949, was not enforceable and that they should not be prosecuted. The U.S. District Court for the Northern District of Texas in Forth Worth had earlier agreed with the plants’ owners that the law had been repealed, was preempted by the FMIA, and violated the dormant Commerce Clause of the U.S. Constitution. However, on January 19, 2007, a panel of the U.S. Court of Appeals for the Fifth Circuit rejected all three arguments, declaring the Texas law to be in force and clearing the way for the state attorney general to prosecute the plant owners if they continued to operate. The two plants have ceased slaughtering for human food, and state legislation (H.B. 2476; S.B. 1742) to legalize operations did not pass during the 2007 session.

Elsewhere, the Illinois legislature in May 2007 passed a law banning horse slaughter. The Illinois plant (owned by Cavel International) was able to operate until September 2007, when the U.S. Court of Appeals for the Seventh Circuit ruled that the state law does not violate the interstate and foreign commerce clauses of the U.S. Constitution.

Recent Federal Legislation

FY2006 USDA Appropriation

During debate on Department of Agriculture FY2006 appropriation (H.R. 2744), the House on June 8, 2005, approved, 269 to 158, a Sweeney amendment to prohibit funds provided in the measure to pay for the ante- mortem inspection of horses under the meat inspection act. On September 20, 2005, the Senate adopted an identical floor amendment by Senator Ensign, by a 69 to 28 vote. The final conference report (H.Rept. 109-255), signed as P.L. 109-97 on November 10, 2005, retained this amendment, but delayed the effective date for 120 days.

Because the FMIA has long required FSIS inspection of equines (like other designated livestock species) before the meat may enter commerce, the amendment’s supporters presumed that the plants could no longer process them for human food. However, the final House-Senate report states: “It is the understanding of the conferees that the Department is obliged under existing statutes to provide for the inspection of meat intended for human consumption (domestic and exported). The conferees recognize that the funding limitation in § 794 prohibits the use of appropriations only for payment of salaries or expenses of personnel to inspect horses.”

Subsequently, the three plants, on November 23, 2005, petitioned Department of Agriculture for voluntary ante-mortem inspection under the 1946 AMA, with the ante-mortem portion funded by user fees. The plants and other horse slaughter supporters noted that the relatively narrow wording of the Sweeney-Ensign language only prohibits use of funds for ante-mortem horse inspection under the FMIA, not for other, post-slaughter inspection activities. They also cited the conference report language, which states that USDA still is obliged to conduct inspections.

On February 8, 2006, USDA-FSIS cited the AMA authority to publish such an interim rule. FSIS amended existing regulations that apply to “exotic species” (bison, deer, etc.), adding a new subpart that applies to horses starting March 10, 2006. Under the new rule, USDA uses many of the same FMIA guidelines for ante-mortem horse inspection. Also, post-mortem horse inspection could continue under the FMIA, using appropriated funds.2 Congressional supporters of the original Sweeney/Ensign amendment objected to the rule, declaring that it circumvented their clear intent to halt horse slaughter.

FY2008 USDA Appropriation

The version of the FY2008 USDA appropriation (H.R. 3161, § 738) passed by the House in late July 2007 would continue a prohibition against using appropriated funds to inspect horses prior to slaughter for human food. Furthermore, the measure would prohibit the USDA-FSIS rule (see above) that has provided for the collection of user fees as well. The committee-reported Senate version (S. 1859) did not include the ban. In lieu of a freestanding FY2008 bill, Congress included USDA funding as Division A of the Consolidated Appropriations Act, 2008 (H.R. 2764), which was signed by the President on December 26, 2007. This consolidated act (§ 741) includes the House language to ban appropriated funds and user fees for horse inspection.

Horse Protection Act

Representative Schakowsky and Senator Landrieu have introduced bills into the 110th Congress (H.R. 503, S. 311) to prohibit permanently the movement and slaughter of horses for human food. These measures, which mirror proposals (H.R. 503; S. 1915) in the 109th Congress by Representative Sweeney and Senator Ensign, would amend the Horse Protection Act (15 U.S.C. §1821 et seq.), which currently makes it a crime to exhibit or transport for the purpose of exhibition any “sore” horse (i.e., one whose feet have been injured to alter its gait). The Schakowsky and Landrieu bills would prohibit the “shipping, transporting, moving, delivering, receiving, possessing, purchasing, selling, or donation of any horse or other equine to be slaughtered for human consumption.” The bills would permit USDA to detain for examination and evidence any horse for which it has probable cause that the animal will be slaughtered for food. Violators would be subject to specified criminal and civil penalties and prison terms. The bills would increase the authorization of appropriations for administering the act from $500,000 to $5 million annually.

In the 109th Congress, the full House had approved H.R. 503 by a 263-146 vote on September 7, 2006, turning aside opposition, and major changes made earlier, by the House Agriculture Committee. Senate action on S. 1915 did not occur. In the 108th Congress, proposed bills (H.R. 857 and S. 2352) to halt horse slaughter differed in detail from the more recent measures. For example, these earlier bills did not amend the Horse Protection Act. H.R. 857 and S. 2352 also explicitly would have required officials to work with animal welfare societies and animal control departments to place confiscated horses temporarily with a nonprofit animal rescue facility, required the owner of a confiscated horse to post a bond sufficient to provide for 60 days of care, and required the Secretary to make grants to specified animal rescue facilities willing to accept confiscated horses.

Wild Horses and Burros

A somewhat related issue revolves around provisions of the Wild Free-Roaming Horses and Burros Act of 1971 (16 U.S.C. §1331 et seq.), which seeks to protect wild horses and burros on federal lands. At issue has been whether, and under what conditions, such horses could be acquired and eventually sold for slaughter. An explanation of this issue can be found in CRS Report RS22347, Wild Horse and Burro Issues, by Carol Hardy Vincent.

Selected Arguments

Most U.S. and Canadian consumers view horses as performance and companion animals rather than food. Horse protection and animal welfare groups contend that Americans overwhelmingly favor an end to horse slaughter for human food, a practice such groups have called cruel and unnecessary. According to these groups, horses are transported long distances often in deplorable conditions in poorly equipped trucks and trailers, where they are exposed to bad weather and often inadequate rest, food, and water.

However, a veterinary journal article counters: “Market demand for horsemeat for human consumption is almost certain to continue and may grow in the foreseeable future. It is therefore proper and necessary that we continue to work with national and international groups to provide humane care for horses intended for slaughter and maintain as much consensus and practicality on these issues as possible.” 3

One concern expressed by opponents of a ban on horse slaughter is that “rescued” horses are more likely to become neglected and abused by owners who lack the knowledge, financial resources, and/or interest to care for them. At the same time, the existing U.S. horse infrastructure cannot absorb the large numbers of animals that would be confiscated or otherwise diverted from slaughter as a result of a slaughter prohibition, opponents of such a ban believe. The American Horse Protection Association (AHPA) is opposed to the slaughter of horses for food but did not endorse the slaughter ban bills in the 108th Congress. AHPA, which maintains a list of U.S. and foreign horse sanctuaries, had observed that not all sanctuaries may have the means or business skills to take in large numbers of horses, and that no nationwide standard-setting or oversight system exists for them.4 A Texas rescue group stated: “Some equine rescues are large organizations with a system of checks that keep everyone honest. Others may be small one or two person operations. There are no national oversight organizations that can verify the honesty of a nonprofit equine rescue.” 5

The National Horse Protection Coalition (NHPC) asserted that sanctuary associations have accreditation programs and “strict guidelines” for the sanctuaries, and that state and local animal welfare laws exist to ensure humane animal care. Others counter that such guidelines, if they exist, have not been endorsed or overseen by any nationally recognized authority, and that most state and local laws are anti-cruelty measures, not proactive care standards.

Some, including the Humane Society of the United States (HSUS), have observed that equine shelters are less well-established than cat and dog shelters, which often are associated with local governments and humane societies. Citing the “extreme costs” and staff time needed to shelter horses, HSUS warned of needing to be aware of “distinctions between sheltering horses and sheltering other companion animals.” 6 The American Association of Equine Practitioners (AAEP) estimated that the cost of a horse’s basic care approximates $1,825 annually, exclusive of veterinary and farrier care. A more recent study estimated the annual cost of caring for an unwanted horse at $2,340.7

NHPC has argued: “Not every horse currently going to slaughter will be rescued by one of these non-profit organizations, but many horses will be kept longer, will be sold directly to a new owner ... or will be humanely euthanized by a licensed veterinarian,” among other alternatives. Euthanasia methods — primarily chemical injection and in some emergency situations, gunshots — are considered by the NHPC and others to be more humane than slaughter, which generally involves stunning with a captive bolt to make the animal unconscious before it is killed and bled. Euthanasia averages from $50 to $150 per horse, a “tiny fraction of the cost of keeping a horse as a companion or work animal,” NHPC has stated in response to arguments about the high expense of dealing with a horse diverted from slaughter.8

Opponents of a slaughter ban contend that disposing of many additional horses each year could create environmental problems, such as soil and groundwater contamination. Ban supporters counter that hundreds of thousands of U.S. horses die naturally or are euthanized each year, and are now safely disposed of. Many are not buried but sent to rendering plants, where their remains are used in industrial products and animal feeds. Renderers already handle millions of cattle and hogs that die before slaughter; another 90,000 horses easily could be absorbed into the existing system, ban supporters maintain.9

As the 110th Congress begins its second session, one aspect of the debate that could re-emerge is whether the unwanted horses that had been sent to U.S. packing plants are now simply moving into Canada and Mexico to be slaughtered there — and if so, what if anything should be done to halt the practice. Supporters of H.R. 503 and S. 311 continue to seek passage of this legislation, which, they believe, would ban such transport.
