Book Review: The Poison Squad

The Poison Squad: One Chemist's Single-Minded Crusade for Food Safety at the Turn of the Twentieth Century
Deborah Blum
Biography, science, politics

In 2010, Deborah Blum published an excellent book entitled The Poisoner's Handbook. The Poison Squad is in many ways a sequel, or para-quel. Unfortunately, the comparison doesn't work in the current book's favor. In The Poison Squad, Blum slips over the line from writer to cheerleader.

The book is centered strongly on Dr. Harvey Wiley, "Father of the FDA". That in itself is a good choice; Wiley was a remarkable character, and provides a unifying thread. However, Blum makes a dreadful choice in her presentation of facts: a reader of The Poison Squad could be pardoned for concluding that everything that Dr. Wiley said, did, or proposed was absolutely righteous, because it was Dr. Wiley saying, doing, or proposing it.

This is nonsense. However well-intentioned Wiley was, and however nefarious his adversaries--and some were pretty nefarious!--he was not a prophet. The eponymous Poison Squad studies were far better than the previous standard, which consisted of nothing; but they would be laughed out of court today, due to tiny sample sizes and a lack of rigor. To use the existence of those studies to support their conclusions is absurd--but Blum does it, over and over. In no case does she even refer even glancingly to the actual, you know, currently-accepted facts. No: Dr. Wiley was always right, and his foes were always wrong (and not just wrong, but EEEVIL).

Blum likes horror stories. She flings around the fact that formaldehyde was used as a food additive like a mad card sharp pulling aces out of her sleeves, apparently because the phrase "formaldehyde in food!!!!" is a scary phrase. She doesn't mention that formaldehyde occurs naturally in some foods, much less give us meaningful facts by which we could compare quantities or make reasoned judgments. She kicks up Wiley-quotin' storm on the terror that is sodium benzoate, but does she include anything like Science Magazine's commentary on the stuff? I'll give you one guess. (Hint: Science uses the terms "idiotic", "stupid", and "Your reasoning is faulty and your science is wrong".) 

At several points Blum's text reads like the "arguments" of today's anti-vaccine zealots. That is not a compliment.

Blum really shows her colors in a rather bad afterword. Here she tries to connect Saint Harvey Wiley to global warming, the Trump Administration, the heartbreak of psoriasis, etc. (Okay, I made that last one up.) This is not only off-putting; it shouldn't be necessary. If Blum had written her book better, she could have--should have--trusted her readers to make the connections for themselves. Instead, the addendum just looks like more frothing and propaganda.

A pretty good book covering some related topics (among many others) is Doris Kearns Goodwin's The Bully Pulpit.
