CEI in 1992 advised the Food and Drug Administration to approve recombinant bovine somatotropin, which is a bioengineered growth hormone. Now surely such recommendation would be accompanied by the further suggestion of labeling the resulting products so that consumer choice- that ultimate driver of market forces-could be openly exercised? Think again: the CEI argued that mandatory labeling of dairy products is inappropriate because it violates the First Amendment (which includes the right to free speech-of the cows?).
