Study Describes Recent Patterns in Salmonella Newport Infections
A CDC study published in Foodborne Pathogens and Disease highlights key regional and demographic features of Salmonella enterica serotype Newport infections in the United States. S. Newport is the third most common serotype causing human infections in the United States, representing about 8% of the estimated 1.2 million Salmonella infections in 2013.
Findings from the study, which analyzed 2004–2013 data from four surveillance systems, include:
- S. Newport infections peaked in 2010, with the highest number occurring in southern states and among children younger than 5 years.
- Most people were infected with strains that were susceptible to all antibiotics tested.
- S. Newport outbreaks have been linked to eating produce items and beef.
- Overall, 8% of S. Newport strain isolates tested were highly resistant to antibiotics.
