By the close of the Industrial Revolution, the American food supply was tainted with frauds, fakes and legions of new and untested chemicals, dangerously threatening the health of consumers. Based on the book by Deborah Blum, The Poison Squad tells the story of government chemist Dr. Harvey Wiley who, determined to banish these dangerous substances from dinner tables, took on the powerful food manufacturers and their allies.
