Draize test leaves rabbits blind in some cases |
Lethal Dosage (LD) tests are used to determine the fatal levels of substances. In some cases 'subjects are forced to ingest poisonous substances until half of them die ... reactions to LD tests include convulsions, vomiting, paralysis and bleeding from the eyes, nose, mouth or rectum'.
Moreover, the results of these tests may not necessarily apply to humans. Peter Tatchell (2009) reports that the human physiology is sufficiently different to those of animals and will therefore counteract any cures derived from animal experimentation. There is no dispute that animal testing provides data, but whatever is discovered from these tests will have to then be re-tested on humans in order to correctly ensure they work. So not only do animals inevitably suffer a cruel cause that could have ultimately been avoided, the patients trying out the novel treatments will also suffer from the irrelevant data collected.
