Find out more about the connection between the
advances in health and medicine, and the crucial role of laboratory
animals.
1. How does laboratory animal research teach
health professionals, medical professionals and
scientists more than what is already known about the human body, injuries
and diseases?
There are striking similarities between the body systems of humans
and various species of animals. For example, much of what we know
about the immune system has come from studies with mice, and much
of what we know about the heart and heart disease treatment and surgery
has come from studies with dogs. In fact, virtually every major medical
advance of the last century is due, in part, to research with animals.
Laboratory animal testing is also required by our federal government
to first provide necessary information that is then used to design
studies using men, women and children as research subjects. It is
important to gauge how a new drug or medical procedure will affect
an entire living body system before using it on humans. All new medical
devices, medical drugs and medical procedures must undergo a scientific
peer review, plus a lengthy legal process of being tested with laboratory
animals, followed by testing with people.
2. Are pets used
in laboratory research?
While there are no absolute guarantees that pets can never be used,
federal laws and local laws in many states exist to protect lost or
stolen pets from inadvertently being used in medical or biomedical research.
In addition, pet owners may purchase microchip identifiers for pets
to wear hidden under the skin. Research facilities routinely scan newly
arrived dogs and cats with an instrument that reads the microchip and
identifies the owner. The pet is then immediately returned to its rightful
owner, and not used with a research study.
The lifelong care and treatment of dogs and cats in research facilities
is extensively regulated. In some states, local policies have been enacted,
such as waiting-periods, to prevent animal pounds and shelters from
selling misplaced pets to research facilities (an example is the state
of Illinois
Animal Welfare Act).
Many research facilities prefer to purchase animals from commercial
animal dealers who breed dogs and cats for the sole purpose of laboratory
research. These dealers must be licensed by the United States Department
of Agriculture (USDA) and must follow strict Animal
Welfare Act standards of care. On the receiving end, research companies
must purchase animals only from those dealers approved by the USDA.
Research companies must also comply with waiting-period requirements,
unannounced USDA inspections, and detailed documentation of animal birth
and origin. Together, all these measures help prevent your pet from
becoming an involuntary research subject.
3. What role do veterinarians play in medical
research with animals?
Veterinarians, who have chosen their
profession because of their concern for animals, are intimately involved
in the care and treatment of laboratory animals. They realize that
results of animal research improve the health of animals as well as
the health of people. Many advances in veterinary medicine are the
direct result of animal research. The Parvovirus vaccine has saved
the lives of many dogs. Heart pacemakers for both humans and animals
were developed through research using dogs. Studies on animal reproductive
physiology have helped prevent certain endangered species from reaching
extinction. Distemper vaccines, tested on Siberian polecats, resulted
in the revitalization of the once disappearing black-footed ferret
population.
Veterinarians are also charged, by federal
law, with the primary role of directing animal care and use programs
for institutions that perform research with animals. The program must
include the training of animal research scientists in the humane and
responsible handling of research animals. The veterinarian also advises
an internal review committee in the approval of all research protocols
before animals may be studied. Staff under the veterinarian may include
licensed veterinary medical technicians.
4. Are there any laws that prevent
research animals from unnecessary pain during the research
study?
Yes. The use of research animals is
strictly controlled, particularly in regard to potential pain as a
result of the study. The Animal Welfare Act was first published in
the U.S. Federal Register in 1966, and numerous amendments have followed
since (for a history of animal welfare laws, see http://www.animal-law.org/welfact/index.html).
Animal comfort is addressed from birth through shipping, housing and
feeding, the duration of the research study, and the animals
death. Clauses in the Act also address exercise for dogs and psychological
well-being for primates. Each research institution must establish
an animal care and use committee that includes a member of the general
public, such as a local veterinarian, church minister, or employee
of the Society for the Prevention of Cruelty for Animals. Membership
on this committee must also include a veterinarian with specific experience
in laboratory animal care. This committee reviews, approves (or disapproves),
monitors and inspects every research study to help ensure that animals
are not subject to unnecessary pain and distress.
Review committees are charged with keeping abreast with, and requiring
research scientists to use, state-of-the-art methodology of preventing
pain in laboratory animals. For instance, an animal that undergoes
a surgical operation, according to approved study, is now given pain
medication that will last after the surgical anesthetic has worn off
and the animal wakes up. The animal is spared immediate post-operative
pain, and also spared pain during the recovery period. In contrast,
small animal veterinarians in private practice dont always give
post-operative pain medication to a pet dog or cat that has just been
spayed or neutered. In general, state-of-the-art procedures are introduced
into laboratory animal medicine long before procedures become routine
in private practice.
Interestingly enough, research studies have also demonstrated that
when animals do not feel pain, they provide more reliable scientific
results.
5. What is
meant by "cruelty-free" as written on cosmetics and consumer
products?
The cruelty-free label is similar to a low-fat
label in the grocery store, in that the implications are somewhat
hidden from the public. Both are marketing strategies to sell a product
by making it appear more desirable than another product. A dieter
will soon learn he cannot lose weight by simply eating fat-free
ice cream. He must also make sure the ice cream is low in sugar and
low in calories. A woman buying a cruelty-free lotion
may assume she is using a product that was not tested on research
animals, but this claim is also misleading.
In reality, all ingredients that make up lotions and cosmetics produced
in the U.S. must have at one time undergone safety tests, generally
using rodents, as required by federal laws enacted several decades
ago. The federal government places high priority on public health
and the safety of its residents. Product safety laws help protect
us from harm, should these products accidentally get into the eyes
or be ingested. Our laws address not only the safety of prescription
eye drops, for example, but also the safety of lubricating drops sold
over-the-counter without a doctors prescription.
When you see a cruelty-free or not tested on animals
label, one of several scenarios may be true. If a new lotion on the
market contains ingredients that were approved years ago by safety
studies using animals, the ingredients do not have to be tested again.
Safety tests on select naturally occurring ingredients are not always
required. If a company manufactures a new product, yet is not involved
in the research of that product, it may still consider itself cruelty-free.
To learn more about product safety laws, read about the Federal
Food, Drug, and Cosmetic Act.
Product safety testing also provides scientific information for poison
control centers and emergency room physicians in the event a product
is misused. Although non-animal models are being developed for product
safety tests, the use of animals in product safety testing is still
the preferred method by many scientists to demonstrate how substances
will react in or on a living body system.
6. Are research methods, such as computer
models, being explored as alternatives to the use of research animals?
Yes. Computer models, cell cultures, and
a number of research methods that compliment animal studies are used
today in biomedical research. In fact, following the recent development
of these complementary research models, the United States Department
of Agriculture reports a reduction in the number of laboratory animals
used in research. These computer models and other non-animal models
are built using research data generated from animal studies. Without
the knowledge gained from animal research, non-animal models would
have no basis. To date, even the most sophisticated technology has
not been able to mimic all the complicated interactions among cells,
tissues and organs that occur in a living body.
Scientists are bound by law to investigate these interactions before
using a new drug or chemical compound in studies with people. In the
early stages of a research study, non-animal models are used to predict
amounts of a chemical compound that would cause irreversible harm
to a live animal. It will then be tested in living animals, and later
tested in living people.
Incidentally, there are strong economic incentives to substitute research
animals with computers or other complimentary non-animal methods whenever
possible. Research animals are extremely expensive to purchase, house,
and oversee during the research study.
7. What is the difference between animal
rights and animal welfare?
Animal rights is the belief
that animals are not ours to usefor food, clothing, entertainment,
or experimentation. There are dozens of animal rights groups in the
U.S. (see http://www.aalas.org/ under links). They vary greatly in type of opposition to the use of
animals and method of carrying out their missions. Opposition varies
from not using animals in research, to not wearing leather shoes.
Methods of protest vary from educational outreach in elementary schools,
to acts of terrorism. In the spring of 2002, following the September
terrorist attacks on the World Trade Centers and the Washington Pentagon,
the FBI declared two animal rights groups, Animal Liberation Front
and Environmental Liberation Front, as the top two terrorist groups
in the U.S.
Animal welfare is a term that sprang up after the federal Animal
Welfare Act passed in 1966. The term is used by research compliance
inspectors employed by the government, and veterinarians and scientists
employed by companies, hospitals, and universities that perform animal
research, all of whom are charged with ensuring that detailed regulations
are followed when using animals in research. People who promote animal
welfare condone the controlled use of animals in research under the
strict guidelines of the Animal Welfare Act and its numerous Amendments.
Proactive animal welfare advocates also adopt the same high standards
for the use of rats, mice, and birds in research, which are not presently
included in the Animal Welfare Act.
