From the Executive Summary: "This exposure assessment does not address a specific emergency scenario, but includes chemicals of concern representing two categories that have been involved in past events. These are diazinon, an organophosphate pesticide, and dioxins/furans, which are persistent organic pollutants. Potential chemical emergency scenarios affecting livestock could include intentional criminal or terroristic acts such as chemical poisoning of food supplies or sabotage of agricultural production or commodity markets. The contamination could be unintentional as well. Examples of unintentional chemical emergencies include industrial accidents, accidental contamination of feed or other agricultural supplies, and transportation-related accidents (e.g., tanker truck or rail car spillage). [...] This report provides information to compare options and support decision-making in the event of actual chemical emergencies. It provides a scientifically based understanding of the potential environmental releases and exposure pathways for each option, and information to evaluate the likely relative contribution of specific exposure pathways based on chemicals of concern, site settings, and steps in carcass management processes. The assessment also can aid selection and priority setting for mitigation and best management practices."
