Marion Nestle talked about her book Pet Food Politics: The Chihuahua in the Coal Mine (University of California Press; July 15, 2008). She tells how in early 2007, a few telephone calls about sick cats set off the largest recall of consumer products in U.S. history, congressional hearings, and an international crisis over the safety of imported goods ranging from food to toothpaste, tires, and toys. Professor Nestle exposes the weaknesses of the global food supply not just for pets, but for farm animals, fish, and, ultimately, for people. She presents a concise look at current food policy and the broader failings of food regulation.

Ms. Nestle’s books include Food Politics: How the Food Industry Influences Nutrition and Health and What to Eat.
