Battelle has been very active for the past 10 years developing terrorism risk assessment methods for the Department of Homeland Security. Out of this research came a software modeling program designed to chart responses to incidents ranging from biological and chemical attacks in public gatherings to the purposeful contamination of a public water supply. Researchers have been able to apply this software, Probabilistic Risk-Informed Analysis, in the poultry industry to focus on the challenges of minimizing Salmonella contamination and understanding where processes are susceptible to Salmonella growth.
