History of World Laboratory Animal Liberation Week

The Institute of World Day for Laboratory Animals was founded in 1979, while the associated Animal Laboratory Week was founded on April 20, 2020. They had both been the driving force behind the movement to end the cruelty of animals In laboratories. They seek to replace the use of animals with scientific treatments that are suitable for the purpose and will discourage the use of animals.

Commercial facilities, universities, pharmaceutical businesses, and medical schools are the most common places where animals are used in research. Living animals were used for experiments by Erasistratus and Aristotle, among the first. Galen, a Roman physician in the second century, dissected pigs and goats after death. Avenzoar, an Arabic physician in Moorish Spain in the 12th century, devised an experimental strategy for testing surgical operations on animals before trying them on humans. Animals have been used in biomedical research from the beginning of recorded history. The Dublin Zoo was founded in 1831 by doctors who were interested in researching both living and dead animals. In the 1880s, Louis Pasteur used anthrax to show the germ theory of medicine. Pasteur demonstrated the germ theory of medicine in the 1880s by introducing anthrax into sheep. For many diseases, the germ theory is the currently accepted scientific theory as it asserts that germs or pathogens are microorganisms that can cause disease.

Toxicology testing became popular in the 20th century. Drug regulations were relatively relaxed in the 19th century. In the United States, for example, the government could ban a drug only after it has prosecuted a company for selling the same drugs that harmed its users. However, in reaction to the 1937 Elixir Sulfanilamide catastrophe, in which the eponymous medicine killed over 100 people, the United States Congress created regulations requiring drug safety testing on animals first before they could be commercialized.
