THE TESTING NUMBERS. “The agency is also significantly increasing the number of annual samples it takes per type of animal slaughtered, from 300 to 800 samples. In 2010, FSIS tested a total of 800 samples for beta-agonists … across 5 categories of livestock. The most samples were taken from beef cows (309), mature chickens (319) and sows (300). One sample was taken from market hogs.”
