'Rath's superb study is a model of intrepid historical investigation, explanatory clarity, analytical acuity, and narrative grace. The stories of faked pig deaths, cattle hidden in volcanic craters, strychnine-filled syringes strapped to the hoods of jeeps, armed livestock inspectors, and deadly assaults on veterinarians make for compelling reading. However, in Rath's hands, they also constitute the all-too-human evidence of the bio-political stakes of managing animals and germs and the fraught development of Mexico's post-revolutionary 'livestock state'.'
