The Centers for Disease Control and Prevention estimates that approximately 1.2 million illnesses occur due to non-typhoidal Salmonella annually in the United States. In the majority of produce-related outbreaks, it is difficult to determine the definitive cause and route of transmission. Since 2002 outbreaks of Salmonella Newport have been associated with tomatoes and cucumbers grown and harvested in the Delmarva region of the East Coast of the United States. Epidemiological evidence supports these finding and makes this area a critical case study for learning and following disease transmission. Research conducted by the FDA and extension specialists in Delmarva provides evidence that this specific strain of S. Newport strain 061 has been found in wildlife, tomatoes, irrigation water, surface water and sediment. This session will cover the historical findings of the unknown reservoirs of S. Newport strain 061 in the Delmarva area, using epidemiologic and environmental findings, grower best practices, and the basic scientific findings in an attempt to cure an endemic contamination issue. The curious case of the Delmarva describes a unique environment with what is perhaps not a unique problem, that is an undetermined reservoir for Salmonella and an engaged community of growers, public health advocates, and researchers. This session will describe many  of the efforts taken over the past 10 or so years by growers and researchers and the past year by the active Delmarva Task Force.
