"Slaughter is different from processing in that the raw material is
alive, has a central nervous system, can express emotional states, and
has biological components like humans." Dr. Janice Swanson, "Why You
Should Care About Animal Welfare," American Meat Institute Foundation's
2002 Annual Animal Handling and Stunning Conference, February 21-22,
2002.
At the poultry slaughter plant each day thousands of birds are crammed
inside crates stacked on trucks waiting to be killed. Truckload after
truckload pulls into the holding dock where huge fans rotate to reduce
the number of birds who will die of heat suffocation while waiting to
enter the slaughterhouse. During the winter, an untold number of birds
freeze to death in the trucks. Others fall out and freeze to the ground
on the docks or along the highway. A forklift picks the topmost pallet
of crates off each flatbed truck, and the birds disappear into the
darkness.
They come out of the darkness. "Live haul involves hand-catching the
birds [some companies now use a mechanical 'harvester'], mostly at
night, in a darkened dust-laden atmosphere and trucking them long
distances," a USDA manual explains (Brant, et al., 23). Birds intended
for meat production are deprived of food and water 8 to 12 hours before
catching to save feed costs and to reduce gastrointestinal splatter at
the plant (Bilgili 2002). "Spent" laying hens, having no further
commercial value, are starved for an average of 4 days before catching,
to "provide a modest net return for the cost of hen disposition"
(Webster 1996, 5), then ripped from the battery cages to the transport
cages, often leaving legs, wings, and heads behind in the cages.
At the slaughterhouse, birds sit in the trucks anywhere from one to nine
hours or more waiting to be killed. Inside the plant, men known as "live
hangers" grab each bird violently from the crates and jam him or her
into a movable metal rack that clamps the birds upside down by their
feet.
Slaughter of "Meat-type" Birds
"A broiler is essentially an overgrown baby bird, easily hurt, sometimes
treated like bowling balls." Bruce Webster, AMI Stunning Conference,
2002.
Live Hang
In the United States and virtually everywhere else, chickens, turkeys,
ducks and other "meat-type" birds are intentionally kept alive through
the slaughter process in order to keep their hearts beating. The birds
are manually pulled from the crates on the flatbed trucks and hung
upside down in the live-hang area of the slaughterhouse, where they may
hang from the shackles in a stationary position anywhere from three to
six minutes or more depending on how fast the lines up ahead are moving.
As Stevenson and many others have observed, suspending these birds (many
of whom are already painfully crippled) with their huge heavy breasts
upside down by their legs from shackles places an extremely painful
strain on their legs and hips (Stevenson, 3.3.1). Adding to this
cruelty, Grandin reports "seeing a lot of one-legged shackling" of birds
(Grandin 2002).
Electrical Immobilization
The birds' heads and upper bodies are dragged through an electrified
water bath trough that is not intended to stun them but to immobilize
them: to keep them from desperately flapping and jerking while hanging
head down from the conveyer belt, to paralyze the muscles of their
feather follicles in order to facilitate feather removal, and to induce
certain characteristics in the muscle tissue marketed to consumers. "A
quality meat product is the objective" of the electrical current,
according to Broiler Industry magazine (Tarver). All of these commercial
goals conflict with the "humane" goal of inducing cardiac arrest (a
heart attack) with a sufficient current that alone, according to
experimental scientists, can insure that most birds will be rendered
permanently unconscious upon receiving it. Duncan (1997, 4) has
correctly noted that the U.S. poultry industry in particular is "not
interested in the humaneness" of the slaughter process.
Neck Cutting
"[B]oth carotid arteries should be severed to ensure a rapid death. . .
. In the 'McLibel' case the Judge found--based on Dr. Gregory's
evidence--that about 9 birds in every 1,000 missed the [stun] bath and
had their necks cut while fully conscious." Peter Stevenson, Animal
Welfare Problems in UK Slaughterhouses, 2001, 3.2.4.
After being dragged through the electrified water bath, the paralyzed
and semi-paralyzed birds have their necks partially cut by a machine
blade and/or a manual neck cutter. (Since 1984 Britain has required a
manual backup.) The fastest method of inducing brain death in birds by
neck-cutting is severing the two carotid arteries that supply the brain
with the fresh, oxygenated blood that maintains consciousness, whereas
the jugular veins carry spent blood away from the brain. Failure to cut
both carotids can add two minutes to the time taken for brain failure to
occur in birds. Worst is the severance of only one jugular vein, which
can cause birds to retain consciousness while in severe pain for up to 8
minutes (Gregory [1984] cited in Davis, Prisoned Chickens, 119;
Stevenson, 3.2.2).
There is every reason to be concerned about the neck cutting procedures
being used in the United States and elsewhere. Various combinations of
neck cutting are recommended on the basis of commercial utility, and the
variables of the birds themselves (like wet or dry feathers and amount
of body fat) and of slaughterhouse conditions are enormous. To these
variables, ignorance may be added, as when The Poultry Tribune talks
about "hopefully hitting the jugular vein" of birds at slaughter (Watts
and Kennett, 7). Moreover, the carotid arteries are deeply embedded in
the chicken's neck muscles, and even more deeply embedded in the
turkey's, making them hard to reach (Gregory [1984] cited in Davis,
Prisoned Chickens, 119).
Bleed Out Tunnel and Scald Tank
There is "strong circumstantial evidence that red-skins have entered the
scald tank while conscious." Ian Duncan, Killing Methods for Poultry,
1997.
The birds then hang upside down for 90 seconds in a bleedout tunnel
while still alive (Bilgili 1992, 136), with an unspecified number of
birds asphyxiating in pools of floor blood if the conveyer belt dips too
close to the bleedout floor (confidential source). They are then
dropped, dead and alive, into tanks of scalding water. If the birds
twist their necks up to avoid the painfully splashing electrified water
and thereafter twist their necks up to avoid the cutting machine, they
are most likely fully conscious upon entering the scald tank, because
they never bled out (Duncan 1997, 2). In Fiscal Year 1993, of
7,085,491,852 total poultry slaughtered in USDA facilities, 3,121,617
birds, known as "red skins" because they are full of blood, officially
entered the scald tank alive (Freedom of Information Act #94-363,
Poultry Slaughtered, Condemned, and Cadavers, 30 June 1994).
Ruptured Blood Vessels
The cruelty of poultry slaughter has increased in recent years because
younger and heavier birds with extremely fragile blood vessels are now
being slaughtered for the fast food and rotisserie trade, resulting in a
greater susceptibility to hemorrhage under an electrical current and
while hanging head down before the current is administered. (Most
chickens-about 35 million a day in the U.S.-- are slaughtered at 6 to 7
weeks old and weigh 4 to 5 pounds, which is several times heavier than a
normal chicken of that age.) Consequently, poultry companies have
reduced the electrical current administered to these baby chickens to
even lower levels (Bowers, 18-19).
In addition, poultry slaughter plants in the U.S., U.K, and elsewhere,
in order to "decrease downgrades caused by muscle contractions during
the stunning process [and] drain more blood from chickens, reducing
blood spots and meat discoloration" ("New Stunner Technology"), are
adopting high frequency currents that "never, or rarely, kill," and
seemingly cause more suffering than ever (Stevenson, 3.3.3).
Gas Stunning
Gas stunning is not commercially employed in the United States. In the
U.K., a 2001 amendment to the 1995 Welfare of Animals (Slaughter or
Killing) Regulations permits the voluntary use of nitrogen and other
inert gases (particularly argon) mixed with low, preferably no,
concentrations of carbon dioxide. This is intended to reduce suffering,
including the fact that the birds can be gassed to death in the trucks
and thus be spared the cruelty of live shackling. According to an
article in Broiler Industry, July 1997, studies of the time taken for
most birds to lose brain responsiveness indicate that the first choice
of gas should be a mixture composed of 90% argon, 2% oxygen, and 8%
nitrogen (Raj 1997).
While conceding the possible welfare benefits of gas stunning under
"ideal" conditions, Compassion in World Farming (CIWF) cites "serious
problems" that could easily arise in commercial slaughter plants. For
one thing, gas stunning "does not lead to immediate insensibility to
pain," according to Stevenson of CIWF (3.2.7). In commercial slaughter
plants, "birds will leave the stunning unit in large numbers and it is
hard to believe that they could be shackled quickly enough to allow neck
cutting which is sufficiently prompt to prevent birds regaining
consciousness from the stun."
According to the European Commission's Scientific Veterinary Committee,
"the interval between the end of stunning and neck cutting will be
considerably longer than the time interval used under the electrical
stunning systems" (cited in Stevenson, 3.2.7). Since, according to the
Committee, "a minimum of 2-minute exposure is required to kill chickens
with the alternative gas mixtures," a question is whether
slaughterhouses will be willing to leave birds in the gas mixture for as
long as 2 minutes" (Stevenson, 3.2.7), given their prioritization of
speed.
Slaughter, CO2 Gassing, and Live Burial of "Spent" Hens
"Some egg producers got rid of old hens by suffocating them in plastic
bags or dumpsters. The more I learned about the egg industry, the more
disgusted I got. Some of the practices that had become 'normal' for this
industry were overt cruelty. Bad had become normal. Egg producers had
become desensitized to suffering."
Dr. Temple Grandin, "What Would the Public Think?" National Institute of
Animal Agriculture, April 4, 2001.
Between 1990 and 1999, the number of laying hens in the world increased
from 3.8 billion to 5 billion (Executive Guide, 36). Spent laying hens
are so osteoporotic from lack of exercise and calcium depletion for
eggshell formation that most slaughter plants won't take them.
Approximately 26 million hens are trucked into Canada from the U.S. each
year to be gassed in the trucks on arrival, according to the May 2000
issue of Animal People (Clifton, 8). Other hens travel long distances to
spent fowl plants that are few and far between in the U.S. Others are
gassed in portable drums, then buried in landfills, or buried without
being gassed. According to one industry source estimate, about 8 to 10
hens per 100,000 are buried alive (Ford). Others suggest a much higher
number.
Because spent laying hens have no commercial value, according to
Canadian Farm Animal Care Trust president Tom Hughes, "They are not even
worth enough money to go through the normal process of slaughtering and
packing. The simplest method of disposal is to pack the birds, alive,
into containers, and bulldoze them into the ground. . . . Another method
is to pack the birds into a closed truck and connect the exhaust to the
body of the truck" (Clifton, 8).
In an article about the Canadian chicken and egg industry in The
Vancouver Courier, the operation of a portable gas unit for spent hens
is described as follows: the live birds "are placed in a funnel-like
opening, from which they're pushed onto rollers, where the birds are
electrocuted, then dropped onto a conveyer belt that loads
them-dead-into the back of a truck" (Miller, 3). Dan Weary, a professor
in the agricultural sciences department at the University of British
Columbia, said that about 1% of hens he watched go through this machine
were not killed by the electrocution and ended up in the truck alive.
According to SPCA spokesman Brian Nelson, many of the hens who survive
the electrocution most likely suffocate under a pile of dead birds
(Miller, 3).
"Humane" Slaughter Laws for Poultry
There are no federal welfare laws governing the raising, transport, or
slaughter of poultry in the United States. Canada has an unenforceable
Recommended Code of Practice, and the U.K. leaves enforcement of its
welfare laws to the Meat Hygiene Service and to an unenforceable
Ministry of Agriculture Code of Practice. As for the EU, a 1997 draft
proposal by the European Commission that was to strengthen an EU
Directive to set legally binding stunning standards for birds and
mammals, "seems to have disappeared" (Stevenson, 2.2; 6.0).
"Humane" Poultry Slaughter Bills Introduced in the U.S. in the 1990s
"[T]he U.S. industry were not interested in the humaneness of the
kill." Ian J.H. Duncan, Killing Methods for Poultry, 1997, 4.
In the United States, Representative Andrew Jacobs, Jr. of Indiana
introduced three Humane Methods of Poultry Slaughter Act bills in the
U.S. House of Representatives in the 1990s: H.R. 4124 (1992); H.R. 649
(1993); and H.R. 264 (1995). These bills sought to amend the 1957
Poultry Products Inspection Act to provide for the "humane" slaughter of
poultry, similar to how the 1906 Meat Inspection Act was used as a basis
for the coverage of "cattle, sheep, swine, goats, horses, mules, and
other equines" under the 1958 Humane Methods of Slaughter Act. However,
all of these bills died in the House Agricultural Livestock Subcommittee
to which they were referred.
On September 28, 1994, Harold L. Volkmer (MO), Chairman of the House
Agriculture Subcommittee on Livestock at the time, held a hearing on
H.R. 649. United Poultry Concerns, the Animal Legal Defense Fund, and
the Animal Welfare Institute presented oral and written testimony on
behalf of H.R. 649 at the hearing, during which Rep. Volkmer joked about
killing chickens while growing up on a farm and stated his opposition to
the bill at the beginning of the hearing.
Argument for "Humane" Poultry Slaughter Legislation
The effort to extend humane slaughter coverage to birds should not be
regarded as a sanction for slaughter. Rather, the absence of a law
conveys the false notion to the general public, and to those who work
directly with poultry, that these birds do not suffer, or that their
suffering does not matter, and that humans have no moral obligation to
them even to the nominal extent granted to cattle, sheep, and pigs. It
means that the majority of warm-blooded vertebrate nonhuman animals
being slaughtered for human consumption in North America are denied the
most basic welfare coverage, and that neither the government nor the
poultry industries in the U.S. and Canada have any legally-mandated
moral accountability regarding the billions of birds they kill.
Birds Suffer the Same as Humans and Other Mammals
"The general public, and many chicken farmers, remain unaware of poultry
sensitivity and behavioral complexity. Their diminished evaluation of
chickens as sentient animals results in inadequate assessment of the
welfare needs of this animal."
Dr. Andrew Fraser, "Poultry Welfare Problems" Canadian Farm Animal Care
Trust Symposium, 1990.
"All poultry species are sentient vertebrates and all the available
evidence shows that they have a very similar range of feelings as have
the mammalian species."
Dr. Ian Duncan, "To whom it may concern" (Letter) September 22, 1994.
"With increased knowledge of the behaviour and cognitive abilities of
the chicken has come the realization that the chicken is not an inferior
species to be treated merely as a food source." Dr. Lesley J. Rogers,
The Development of Brain and Behaviour in the Chicken, 1995, p. 213.
"[I]t is now clear that birds have cognitive capacities equivalent to
those of mammals, even primates." Rogers, Ibid, p. 215.
Birds experience pain and suffering the same as humans and other
mammals; they have the same nociceptors-pain receptors-as do humans.
They have the same capacity for fear, misery, and terror. They possess
conscious awareness of their surroundings and their experience. In "Pain
in Birds," Dr. Michael Gentle writes: "Comparing pain in birds with
mammals, it is clear that, with regard to anatomical, physiological, and
behavioural parameters measured, there are no major differences and
therefore the ethical considerations normally afforded to mammals should
be extended to birds "(Gentle, 235).
Future Prospects
Federal Legislation in the U.S.
Though no truly humane system of slaughter can be devised, the current
situation in the United States could be improved by redefining
"livestock" in the federal Humane Methods of Slaughter Act (1958) to
include poultry, or by amending the 1957 Poultry Products Inspection Act
to include a humane slaughter provision for poultry.
State Anti-Cruelty Laws in the U.S.
In some states, the worst poultry slaughter abuses might be prosecuted
under state anti-cruelty laws, a prospect that should be investigated.
States that already have humane slaughter laws should adopt amendments
specifically to include poultry, as was done in California in 1991.
(State laws regulate products sold within the state as opposed to
interstate commerce, which is regulated by the federal government.)
Eliminate/Prohibit Electrical "Stunning"
The term "stun" is a misnomer as applied to the standard poultry
slaughterhouse practice of shooting a live current through the birds by
means of an electrified knife, plate, or electrified saltwater.
Electrified saltwater is the method used by the commercial poultry
industry in the United States, Canada, and Europe for "meat-type" birds.
After the birds have been manually jammed into the movable metal rack
that clamps them upside down by their feet, their heads and necks are
dragged through a 12-foot-long trough filled with filthy water that
shoots painful volts of electricity through them for approximately 7
seconds (Bilgili [1992] cited in Davis, Prisoned Chickens, 115).
Pre-Stun Shocks
In addition to the inherent cruelty of electrified water bath immersion,
many birds experience pre-sun shocks as the electrified water splashing
out of the stunner hits them prior to immersion. Because their long
wings hang lower than their heads, turkeys and geese are especially
vulnerable to pre-stun shocks through their wings (Stevenson 3.3.2), but
all birds are vulnerable to this painfully splashing water and to the
electrically alive ramp at the stunner entrance (Davis, Prisoned
Chickens, 115-116; Stevenson, 3.2.3; 3.3.2).
Because the purposes of the "stunner" are immobilization. feather
release, and meat characteristics-not humane slaughter, and because the
currents deemed by experimental scientists to be the least inhumane (a
minimum of 120 mA for each chicken and more than 250 mA for each turkey
and duck) rupture the birds' fragile blood vessels, the birds are
intentionally administered only 12.5 mA - 25mA, and are thus tortured.
(Gregory and Wilkins; Davis, 167, note 64; Duncan 1997: 4-5; Raj 1998:
3, 5; Webster 2002).
In this condition of suffering, the birds approach the neck cutter and
move from there into the bleedout tunnel, all the while hanging upside
down from the conveyer belt. Humans receiving somewhat similar
low-amperage electroconvulsive treatments have reported experiencing
"thunderbolts in their heads" (Grandin 2002).
Gas Stunning
"It is logical to suggest that the stress associated with the electrical
stunning of poultry should not be replaced with the stress of induction
of anesthesia with an atmosphere containing a high concentration of
carbon dioxide." A.B.M. Raj, "European Perspective on Poultry
Stunning," Broiler Industry, July 1997.
"[I]n order to prevent birds regaining consciousness, it is essential
that they are killed (rather than stunned) by the gas mixture." Peter
Stevenson, Animal Welfare Problems in UK Slaughterhouses, July 2001.
Research conducted in the United Kingdom has shown that given a choice,
most chickens, turkeys, and pigs avoid an atmosphere containing a high
concentration of carbon dioxide. By contrast, most chickens, turkeys,
and pigs reportedly show no aversion to the presence of 90% argon or 30%
carbon dioxide in a feeding chamber. Argon is heavier than air and thus
fairly easy to contain (Raj 1997).
Based on the evidence, the U.K. approved, in 1995, two gas mixtures with
a proportionally high percentage of argon (60% and 90%). In 2001, as
noted, the British government amended the U.K.'s Welfare of Animals
(Slaughter or Killing) Regulations 1995 (WASK), permitting higher
concentrations of inert gases (argon and/or nitrogen), and consequently
lower concentrations of carbon dioxide to be used on a voluntary basis
in the gas stunning of poultry.
From a welfare standpoint, behavioral and electrophysiological
investigations into the time to loss of brain responsiveness in chickens
and turkeys have indicated that the first choice of gas should be 90%
argon in air, leaving 2% oxygen and 8% nitrogen from air, and the second
choice should be a mixture of 30% carbon dioxide and 60% argon in air,
leaving 2% oxygen and 8% nitrogen from air. At this level of carbon
dioxide, and absolutely no higher, the aversive effect is said to be low
(Raj 1997).
But . . .
Notwithstanding, it is crucial that residual oxygen be maintained at
less than 2% to ensure rapid brain function loss, as researchers have
found that air trapped between birds or crates or in the feathers of
birds can raise the residual oxygen to levels that prevent loss of
consciousness (Duncan 1997, 7).
It is also crucial that the birds be killed, not merely stunned, by the
gas, according to Stevenson, who cites the EU Scientific Veterinary
Committee (SVC) Report, which states that if birds are only stunned
rather than killed with gas mixtures, they regain consciousness "very
rapidly" (Stevenson, 3.2.7).
According to Compassion in World Farming:
- If gas is used, the industry should adopt the gas mixture that causes
less distress, i.e. 90% argon.
- Because gas-stunned birds regain consciousness rapidly, they must be
killed, rather than stunned, by the gas.
- The use of 30% oxygen and 40% carbon dioxide is completely unacceptable
because this mixture prolongs the time taken for birds to reach
unconsciousness (Stevenson, Conclusions).
Proponents of the gas stun/kill method propose that the relative
cheapness of nitrogen (which is the main component of air, has the same
density as air, and is thus as difficult to contain as air) should
encourage poultry producers to adopt gas killing systems that could
improve welfare standards, including the fact that the birds can be
killed in the transport crates before being shackled, and thus be spared
the pain and stress of live shackling and the cruelty that follows: neck
cutting, bleed out, and, for many millions of birds each year, the scald
tank (Duncan 1997: 5-10).
Postscript
In 1997, Dr. Ian Duncan, Professor of Poultry Ethology and Chair in
Animal Welfare at the University of Guelph in Ontario, Canada, visited
the first commercial gas stunning installation in Europe at Eye, Suffolk
in eastern England The slaughter plant he visited is owned by Grampian
Poultry, the largest poultry slaughter company in the U.K. His
observation, of birds (in drawers holding 20-24 birds each) entering a
tunnel containing a mixture of 30% carbon dioxide and 60% argon in air
with a residual mixture of 8% nitrogen and 2% oxygen, convinced him that
this is "the most stress-free, humane-method of killing poultry ever
developed. The birds are quiet through the operation. They remain in the
transport crate until dead and the killing procedure itself is fast,
painless and efficient. There is no risk of recovery from
unconsciousness" (Duncan, 1997: 8-10).
