LD50 Test - After years of killing...

"It is the opinion of the NSMR that the routine use of the quantitative LD50 test is not now scientifically justified . . ."
~ National Society of Medical Research

"There is really little scientific justification for the test because reproducibility is
not good, it can even vary from day to day, and the results are dependent on the animal strain used . . ."
~ P.S. Rogers, Managing Director,
Hazelton Laboratories Europe Ltd.

". . . it is simply not possible with all the animals in the world to go through new chemicals in the blind way that we have at the present time, and reach credible conclusions about the hazards to human health . . ."
~ Joshua Lederberg, Ph.D
Nobel Prize winning geneticist
and President of Rockefeller University
