As with Doris Faber's Enough! (1972), May's title is misleadingly snappy. Easily the first half of his history of food and drug legislation is about chemist Harvey Wiley's untiring fight around the turn of the century against harmful food additives and false labeling. Some of Wiley's practices--such as using human guinea pigs--are worth looking into, but here they are only further items to report along with the ups and downs of various proposals, bills and officials. The rest of the book skims more rapidly through sulfas and K-rations, FDA and UNESCO, Kefauver's Committee and Nader's Raiders, Japanese mercury poisoning and Vietnamese defoliation, in a flat undifferentiated summary that ignores the relative importance and implications of the topics and sacrifices selective elaboration in favor of listing more names, agencies and amendments.
