May 28, 2014 -- Salmonella poisoning linked to Foster Farms chicken has been confirmed in 50 more people, bringing the total to 574 cases in 27 states since March 2013, the U.S. Centers for Disease Control and Prevention said Tuesday.
Since the last agency update in April, there have been an average of eight new cases a week. While there appears to be a decline in the number of new cases reported each week, the outbreak isn't over, said Dr. Rob Tauxe, the CDC's director of foodborne, waterborne and environmental diseases, NBC News reported.
He added that the new cases appear to be linked to fresh, retail chicken and not chicken that had been kept in home freezers for months.
The CDC said that nearly 40 percent of people who became sick during the outbreak have been hospitalized, and 13 percent have developed life-threatening blood infections, which is triple the rate in typical salmonella outbreaks, NBC News reported.
