Conventional toxicological testing methods are often decades old, costly and low-throughput, with questionable relevance to the human condition. Several of these factors have contributed to a backlog of chemicals that have been inadequately assessed for toxicity. Some authorities have responded to this challenge by implementing large-scale testing programmes. Others have concluded that a paradigm shift in toxicology is warranted. One such call came in 2007 from the United States National Research Council (NRC), which articulated a vision of ‘‘21st century toxicology” based predominantly on non-animal techniques. Potential advantages of such an approach include the capacity to examine a far greater number of chemicals and biological outcomes at more relevant exposure levels; a substantial reduction in testing costs, time and animal use; and the grounding of regulatory decisions on human rather than rodent biology. In order for the NRC’s and similar proposals to make a significant impact on regulatory toxicology in the foreseeable future, they must be translated into sustained multidisciplinary research programmes that are well coordinated and funded on a multinational level. The Humane Society is calling for a ‘‘big biology” project to meet this challenge. We are in the process of forging an international, multistakeholder consortium dedicated to implementing the NRC vision.
