THUS, OUR OBJECTIVES ARE TO:DEVELOP A VALIDATED LABORATORY METHOD TO DETECT INFECTIOUS NOROVIRUS CONTAMINATION IN THE AGRICULTURAL ENVIRONMENTDEVELOP A NEW RISK MODEL TO MEASURE THE RISK TO US CONSUMERSPRIORITIZE PRODUCE SAFETY STRATEGIES TO REDUCE INFECTIOUS NOROVIRUS CONTAMINATION ON PRODUCE IN THE HARVEST AND POST-HARVEST ENVIRONMENT THAT MAXIMIZE PUBLIC HEALTH IMPACTTHESE IMPACTS WILL IMPROVE THE SAFETY OF U.S. AGRICULTURAL MARKETS AND CONSUMERS AND IMPROVE THE U.S. AGRICULTURAL ECONOMY.
