Salmonella Enterica Serovars with Multidrug Resistance Detected in North Carolina Poultry

What's Happening?

A study has identified 132 Salmonella enterica isolates from poultry retail meat in North Carolina, revealing the presence of multidrug-resistant strains. These isolates, collected between 2020 and 2024, include 25 different serovars, with S. Infantis and S. Kentucky being the most prevalent. The study highlights the presence of the bla CTX-M-65 gene, which confers resistance to broad-spectrum cephalosporins, complicating treatment options. The findings underscore the importance of monitoring antimicrobial resistance in food production to prevent zoonotic transmission.

Why It's Important?

The detection of multidrug-resistant Salmonella strains in poultry poses a significant threat to public health, as these strains can lead to difficult-to-treat infections in humans. The study emphasizes the need for continuous surveillance and improved food safety practices to mitigate the spread of resistant bacteria. This issue is critical for both human health and the agricultural industry, as it affects consumer safety and the reputation of food producers.
