In this episode of Food Safety Matters, we speak with Deborah [04:18] about:

  • The shocking discoveries Deborah made about food safety in the 19th century while writing her book, The Poison Squad, which chronicles the passage of the 1906 Pure Food and Drug Act
  • How the unregulated food industry’s prioritization of profits over public health led to food being one of the top ten causes of death during the latter half of the 19th century, which is also sometimes referred to as the period of the “Great American Stomachache”
  • The different kinds of risk associated with food in urban versus rural environments
  • The issues of adulteration and the lack of labeling requirements in the 19th century
  • The questionable ethics of the Hygienic Table Trials that were conducted by U.S. Department of Agriculture (USDA) Chief Chemist Dr. Harvey Wiley, in an effort to convince industry, regulators, and the public that the compounds being added to foods were harmful to human health
  • The impacts that Dr. Wiley’s experiments had on public perceptions of food safety and the progression of U.S. food regulation, and the role that media played in disseminating Dr. Wiley's findings
  • How behind-the-scenes relationships between food industry regulators, politicians, and the scientific community may weaken the law, both in present day and the 19th century
  • Deborah’s biggest revelation from researching and writing The Poison Squad—a grim case of formaldehyde in milk.

We also speak with Larry [59:42] about The Poison Squad from industry’s point of view, including conversations about:

  • Possible reasons why the food industry neglected to ensure the safety of substances it was adding to food products in the 19th century, including a lack of technical capability and regulation
  • Changes in regulations and public sentiment around food safety over the last century, and how the general approach to food safety has been guided by discordant views among different stakeholder groups
  • How the antagonism that occurred at the highest levels of the federal government during the events chronicled in The Poison Squad set in motion a series of events that gave passage to future food safety legislation
  • The successes that scientifically minded food safety advocates in the U.S. have made since the enactment of the 1906 Pure Food and Drug Act, and improvements that need to be made regarding international harmonization
  • Results that can arise from the friction between industry’s need to turn a profit versus the drive to do right by consumers, as well as the economic value of ensuring food safety versus cutting corners.
