Animal Testing Policy Gets a Facelift
Worldwide, more than 100 million animals are used every year in laboratory experiments. Many of them suffer terribly; virtually all are killed in the process. As a key part of our work to help animals in laboratories, we push for scientific efforts to replace animal testing with more sophisticated alternatives.
A particularly crude and infamous test is the Lethal Dose 50 percent test, in which various doses of a substance are given to groups of animals in order to determine the amount that kills 50 percent of them. Developed in the 1920s, the LD50 test is now being replaced by a variety of procedures, some of which use fewer or no animals. Yet some uses of this inhumane test persist
One of the most disturbing examples is the testing of batches of Botox© and related products that share the same active ingredient: the potent botulinum neurotoxin.
