[QUOTE="Exfarmer, post: 8129377, member: 1951"] All toxicological tests are done using certain standards. They use LD50 as a test of the toxicity. Thisis the dose which will kill 50% of the lab animal. The standard of course is rats but they can use other creatures . it is known that LD 50 is a very imprecise way of assessing the dangers of a particular material, with many animals showing no issue with exposure while many others of closely related species being damaged severely. We now know that if the proverbial Guinea Pig were used for testing penicillin, it would never have reached the doctors as it is very poisonous to them [/QUOTE]
