- A total of 907 people infected with the outbreak strains of Salmonella Poona were reported from 40 states.
- A total of 204 ill people were hospitalized, and six deaths were reported from Arizona (1), California (3), Oklahoma (1), and Texas (1). Salmonella infection was not considered to be a contributing factor in two of the three deaths in California.
- Epidemiologic, laboratory, and traceback investigations identified cucumbers imported from Mexico and distributed by Andrew & Williamson Fresh Produce as the likely source of the infections in this outbreak.
- Two recalls(http://www.cdc.gov/salmonella/poona-09-15/advice.html) of cucumbers that may be contaminated with Salmonella were announced in September 2015 as a result of this investigation: Andrew & Williamson Fresh Produce and Custom Produce Sales.
- Investigation of illnesses that were reported after the peak of the outbreak in August and September 2015 did not identify an additional food linked to illness. The source of contamination for the cucumbers distributed by Andrew & Williamson Fresh Produce has not been identified.
