The illnesses began November 18, 2018 through June 13. Interviews with those affected indicated pig ear dog treats are the likely source of this outbreak, but a common supplier of the dog treats has not been identified.
Most people with salmonella develop diarrhea, fever, and stomach cramps 12 to 72 hours after being exposed to the bacteria. The infection usually lasts four-to-seven days and most recover without treatment; however some people may need to be hospitalized and young children, pregnant women, the elderly and people with weakened immune systems are more likely to have a severe illness.
The CDC said the investigation is still ongoing.MORE NEWS: San Francisco Transit Officials Reopen Muni Metro Stations; Restore F-Line Trolley Service To Fisherman's Wharf
