The answer probably lies in the fact that half a century had elapsed without any indication that animal feed containing ovine protein was infecting sheep or any other animal." Purdey
Alternatives to animal testing for "Safety Evaluation Ultimately Replacing Animal Testing". It is called "SEURAT-1" to indicate that more steps have to be taken before the final goal will be reached. SEURAT-1 will develop knowledge and technology building blocks required for the development of solutions for the replacement of current repeated dose systemic toxicity testing "in vivo" used for the assessment of human safety. SEURAT-1 is composed of six research projects, which started on January 1, 2011 and will run for five years. These projects will closely cooperate with a common goal and combine the research efforts of over 70 European universities, public research
