In this episode of the MacNeil/Lehrer Report, guests discuss a recent report from a panel at the National Academy of Sciences' Institute of Medicine recommending changes to food safety laws. The report follows Congress' decision to suspend a saccharin ban, despite the fact that under current law the Food and Drug Administration must ban food additives like saccharin which cause cancer in animals. The panel recommends that the FDA instead classify substances as having high, medium, and low health risks, and that they be advertised to the public in that manner. Guests include two members of the panel - one in support of there recommendation and the other against it - as well as the FDA Commissioner.
