Case Count Update
Since the last update on April 16, 2018, 12 more ill people were added to this outbreak.
As of April 16, 2018, 35 people infected with the outbreak strain of Salmonella Braenderup have been reported from 9 states. A list of the states and the number of cases in each can be found on the Case Count Map page. Illnesses started on dates ranging from November 16, 2017 to April 14, 2018. Ill people range in age from 1 to 90 years, with a median age of 65. Fifty percent of ill people are female. Of 28 people with information available, 11 (39%) have been hospitalized and no deaths have been reported.
Illnesses that occurred after March 23, 2018, might not yet be reported due to the time it takes between when a person becomes ill with Salmonella and when the illness is reported. This takes an average of two to four weeks.
Whole Genome Sequencing (WGS) analysis did not identify antibiotic resistance in bacteria isolated from 22 ill people. Testing of three clinical isolates using standard antibiotic susceptibility testing methods by CDC’s National Antimicrobial Resistance Monitoring System (NARMS) laboratory also did not show any resistance.
