California's Proposition 65 contains hundreds of unique chemicals, and the way in which consumers are exposed to these chemicals differs considerably depending on factors such as chemical properties, our physiological defenses against these chemicals, and the sources of potential exposure. The Prop 65 list contains a number of substances that are readily avoidable in the marketplace, meaning that they are intentionally added to products and thus a straightforward mechanism exists for reducing or eliminating exposure. However, the Prop 65 list also contains a large number of chemicals that are not-readily avoidable, such as chemicals inherent in our environment. These inherent chemicals are particularly important for food risk assessment because their presence in the environment carries over into our food supply by plants and animals absorbing these chemicals. This session will provide an overview of how risk assessment and management differs between readily avoidable and not readily avoidable substances, compare how risk assessment agencies incorporate data on natural occurrence into their risk assessments, and investigate how risk assessment of food chemicals is evolving.
