Summary
Nearly 105,000 horses were slaughtered in the United States in 2006 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 the practice continues, funded
by industry user fees. Debate continues on the acceptability of horse slaughter, and how
to care for and/or humanely dispose of horses if they no longer went for human food.
Also in the 109th Congress, the full House approved a bill (H.R. 503) to ban horse
slaughter, but no action occurred on a Senate version (S. 1915). New bills in the 110th
Congress to ban slaughter include H.R. 503 and S. 311. This report will be updated.
Overview
Nearly 105,000 horses were slaughtered in the United States in 2006 for human
consumption, virtually all for export, according to the U.S. Department of Agriculture
(USDA). The largest markets were France, Belgium, Switzerland, Italy, Japan, and
Mexico. The United States exported about 16,000 metric tons of horse meat valued at
about $60 million in 2006 (January-November). Most of these horses are raised for other
purposes — the majority for riding — but no longer wanted by owners; they are collected
by dealers who supply the foreign-owned plants from auctions, boarding facilities, and
elsewhere. Two Texas plants and a third plant in Illinois slaughter them. Although U.S.
horse slaughter has been rising since 2002, it remains 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
small 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

CRS-2
these laws may set care standards, although more are likely to be anti-cruelty measures.
However, U.S. horse slaughter plants are 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 may have to be shipped long distances to reach the few plants now
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
Texas Legal Action. Several states — including Texas — have passed 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, 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 in the lower court’s ruling, declaring the
Texas law to be in force and clearing the way for the state attorney general to prosecute
the plant owners if they continue to operate.2 Meanwhile, the plants could seek a reversal
in the full appeals court or the U.S. Supreme Court.
Recent Legislation
Amendment to FY2006 USDA Appropriation. During debate on USDA’s
FY2006 appropriation (H.R. 2744), the House on June 8, 2005, approved, 269 to 158, a

Cir., Jan. 19, 2007).

CRS-3
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 Section 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 USDA 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 continues under the FMIA, using
appropriated funds.3 Congressional supporters of the original Sweeney/Ensign
amendment objected to the rule, declaring that it circumvents their clear intent to halt
horse slaughter. Several animal welfare groups sued to challenge the rule, but it has
remained in effect.4
Horse Protection Act. Representative Schakowsky and Senator Landrieu have
introduced bills into the 110th Congress (H.R. 503, S. 311) to prohibit 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,
3 USDA’s rule estimated that the new fees would amount to between $68,000 to $102,000 during
FY2006. Total salary costs for the six federal inspectors who staff the three horse processing
plants are about $400,000 per year; this excludes some expenses such as lab fees and the costs
of relief inspectors. Source: May 16, 2006 telephone communication with FSIS budget official.

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. The committee had adopted amendments that would have
permitted the three current plants to continue operating; made the bill a pilot program for
Kentucky and New York, where none of the three operate; required USDA to compensate
any horse owner for economic losses incurred due to a ban, to assume responsibility for
all unwanted horses, and to reimburse state and local governments for their costs in
dealing with unwanted horses; and exempted the slaughter of horses for food for
charitable and humanitarian purposes. 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. In the 108th Congress,
a provision in the Consolidated Appropriations Act for FY2005 (§142, P.L. 108-447)
gave federal agencies new authority to sell, “without limitation,” excess animals (or their
remains) that essentially are deemed too old (more than 10 years old) or otherwise unable
to be adopted (tried unsuccessfully at least three times). A second change removed
provisions of law that had barred wild horses and burros and their remains from being
sold for processing into commercial products. A third change removed criminal penalties
for processing into commercial products the remains of a wild horse or burro, if it is sold
under the new authority. Also, the law did not expressly prohibit the Interior
Department’s Bureau of Land Management (BLM) from slaughtering healthy wild horses
and burros, as had annual appropriations bills apparently each year starting in FY1988.5
These changes were supported as a cost-effective way to help the agencies achieve
“appropriate management levels” (AMLs), to improve the health of the animals, protect
range resources, and restore a natural ecological balance on federal lands. The changes
have been opposed, particularly by animal rights activists, as potentially leading to the
slaughter of large numbers of healthy animals. According to BLM, about 8,200 animals
are available for sale, with 1,700 having been sold and delivered as of March 2006. More
than 31,000 wild horses and burros are on the range, with the national AML set at just

above 28,000, according to BLM estimates. BLM manages another 25,000 animals in
holding facilities. A bill (H.R. 249) in the 110th Congress is intended to overturn the
changes; similar bills (H.R. 297/S. 576) to do so, and to foster adoptions and sales (H.R.
2993/S. 1273), were offered in the 109th Congress.
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.”6
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.7 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.”8
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.”9 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 $2,340.10
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.11
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.12
The horse slaughter debate “has brought attention to the plight of tens of thousands
of unwanted horses,” the American Veterinary Medical Association (AVMA) declared
recently. Many thousands of unwanted horses exist beyond those horses slaughtered for
human food and the wild horses rounded up by BLM but not adopted, according to horse
experts who participated in a recent panel discussion. Cutbacks in the pregnant mare
urine industry have also left many thousands of mares without homes.13
