Pregnant women are more likely to get listeria than the average population. Listeria is a very dangerous foodborne illness and can cause miscarriage or stillbirth. The last big outbreaks of listeria were due to cantaloup, which appears nowhere on the like restricted list.
Emily Oster of the University of Chicago and author of Expecting Better talks with EconTalk host Russ Roberts about her book on pregnancy and the challenges of decision-making under uncertainty. Oster argues that many of the standard behavioral prescriptions for pregnant women are not supported by the medical literature. The conversation centers around the general issue of interpreting medical evidence in a complex world using pregnancy advice as an application. Alcohol, caffeine, cats, gardening and deli-meats and their effect on pregnant women are some of the examples that come up. The conversation closes with a discussion of Oster's work on hepatitis-B and the male-female birth ratio.
