In August 2011, CDC identified a sustained increase in the number of Salmonella Heidelberg isolates with the outbreak strain reported to PulseNet from New York and New Jersey. From April 1 to November 4, 2011, a total of 157 illnesses were reported in New York (93 cases) and New Jersey (64 cases). Based on the previous 5 years of reports to PulseNet, New York and New Jersey would expect approximately 5 cases per month, but in June through August 2011, these states experienced approximately 30-40 cases a month. No significant increase in the number of illnesses above baseline was identified in other areas in the United States during this period.
Among persons for whom information is available in New York and New Jersey, illnesses began on or after March 13, 2011. Ill persons range in age from <1 to 97 years with a median age of 10 years. Fifty-two percent are female. Among the 125 ill persons with available information, 21 (17%) have been hospitalized. No deaths have been reported.
