Sprouts Extraordinaire Salmonella Outbreak Lawsuit - Colorado (2016)
CDC collaborated with public health officials in several states and the U.S. Food and Drug Administration (FDA) to investigate a multistate outbreak of Salmonella Reading and Salmonella Abony infections.
Public health investigators used the PulseNet system to identify illnesses that may have been part of this outbreak. PulseNet, coordinated by CDC, is the national subtyping network of public health and food regulatory agency laboratories. PulseNet performs DNA fingerprinting on Salmonella bacteria isolated from ill people by using techniques called pulsed-field gel electrophoresis (PFGE) and whole genome sequencing (WGS). CDC PulseNet manages a national database of these DNA fingerprints to identify possible outbreaks.
Thirty-six people infected with the outbreak strains were reported from nine states. Of those ill people, 30 were infected with Salmonella Reading, 1 was infected with Salmonella Abony, and 5 were infected with both.
Illnesses started on dates ranging from May 21, 2016 to September 10, 2016. Ill people range in age from less than 1 year to 72, with a median age of 30. Fifty-six percent of ill people were female. Seven ill people reported being hospitalized, and no deaths were reported.
Epidemiologic and traceback evidence indicated that alfalfa sprouts supplied by Sprouts Extraordinaire of Denver, Colorado were the likely source of this outbreak. In interviews, ill people answered questions about the foods they ate and other exposures in the week before they became ill. Of the 31 ill people who were interviewed, 18 (58%) reported eating or possibly eating alfalfa sprouts in the week before illness started. This proportion is significantly higher than results from a 2006 survey of healthy people, in which 3% reported eating raw alfalfa sprouts on a sandwich in the week before they were interviewed. Ill people in the current outbreak reported eating raw sprouts on sandwiches from several restaurants.
Federal, state, and local health and regulatory officials performed a traceback investigation from five restaurants where ill people reported eating alfalfa sprouts. This investigation indicated that Sprouts Extraordinaire supplied alfalfa sprouts to all five of these locations.
On August 5, 2016, Sprouts Extraordinaire recalled its alfalfa sprout products from the market due to possible Salmonella contamination. These products were sold in boxes labeled “5-lb Living Alfalfa.”
