According to a study published in Emerging Infectious Diseases, the annual incidence of resistant non-typhoidal Salmonella infections in 2015 and 2016 was 40% higher than it was between 2004 and 2008.

“Salmonella is a major cause of foodborne illness in the United States. Antimicrobial resistant infections pose a particular public health threat as they are linked to more severe illnesses. ” To congratulate medal, MD, MS, an epidemiologist in the CDC’s food, aquatic and environmental disease division, Healio said.

“For the study, we estimated the changes in the incidence of Salmonella infections resistant to antimicrobial drugs recommended for treating severe infections over the period 2004-2016,” Medalla said. “These data will help public health practitioners set goals and priorities for reducing the number of antimicrobial-resistant Salmonella infections in the US population.”
Medalla and CDC colleagues used models of culture-confirmed Salmonella infections between 2004 and 2016 from two CDC surveillance systems to estimate changes in the national incidence of resistant non-typhoidal Salmonella infections.
Overall, the researchers estimated that between 2004-2008 and 2015-2016, the annual incidence of Salmonella infections with clinically meaningful resistance to any of the three antimicrobial drugs recommended for treating severe infections increased by an estimated 40%. Medalla said the increase means about 63,000 more resistant infections each year.
The study also showed that changes in the incidence of resistance varied by serotype, with two serotypes responsible for two-thirds of the increased incidence of clinically meaningful resistance in 2015-2016. In addition, more than half of the increase was due to ciprofloxacin-non-susceptible infections.
“The increase in antimicrobial resistant Salmonella infections is a worrying trend. Although most Salmonella infections result in self-limiting disease, antimicrobial treatment is recommended for patients with severe infection or at high risk of complications, ”Medalla said. “Preventive measures that can reduce the risk of Salmonella infection include washing your hands properly, handling food safely, avoiding contact with animals that are more likely to carry the bacteria (e.
