Interpretive Summary: The purpose of this presentation is to address the question: "Could chronic toxicants be used to create a terrorism incident?" If so, what may happen and what can be done to minimize the impact. Chronic toxicants are "chemicals that are known or suspected to cause disease through mechanisms that require low level and long-term exposure." This is in contrast to acute toxicants, which are usually used at high dosages, or are extremely poisonous, and the toxic effects are seen very quickly. For chronic toxicants the food safety impact is presumably an increased risk of chronic disease. There are political impacts as well. The probability that a terrorist could cause increased risk of chronic disease through intentional contamination of foods with toxic chemicals that are known to cause chronic diseases is very low. However, intentional contamination, even with non-toxic doses and short-term exposure could be very disruptive to the food supply. The amount of material that would be required to create an incident could be very small due to the public's low tolerance for uncontrollable and unobservable risks. The choice of which product to contaminate would depend on the chemical, physical, and organoleptic properties of the food and the toxicant.
