This case study, developed by the New York Integrated Food Safety Center of Excellence, was adapted from an actual Salmonella investigation initiated by the New York State Department of Health in 2011, heralding a multistate outbreak. It was the first Salmonella outbreak in the U.S. associated with pine nuts. The case study is designed to be completed as a self-paced individual activity or as a moderated small group exercise. Obtaining shopper card information and engaging industry proved essential throughout this cluster investigation. Product recalls likely prevented additional illnesses. As evidenced in this outbreak investigation, early identification of patient exposures can assist in determining a common source of infection so that effective control efforts can be implemented.
