The 2013 Statistics of Scientific Procedures on Living Animals reveal that the level of animal experimentation in Great Britain continues to rise, with 4.12 million procedures being conducted. The figures indicate that this is almost exclusively a result of the breeding and use of genetically-altered (GA) animals (i.e. genetically-modified animals, plus those with harmful genetic defects). The breeding of GA animals increased to over half (51%) of all the procedures, and GA animals were involved in 61% of all the procedures. Indeed, if these animals were removed from the statistics, the number of procedures would actually have declined by 4%. It is argued that the Coalition Government has failed to address this issue, and, as a consequence, will not be able to deliver its pledge to reduce animal use in science. Recent publications supporting the need to reassess the dominance of genetic alteration are also discussed, as well as the need to move away from the use of dogs as the default second species in safety testing. The general trends in the species used, and the numbers and types of procedures, are also reviewed. Finally, forthcoming changes to the statistics are discussed.
