Researchers at the University of the Philippines Diliman have discovered high levels of multidrug-resistant (MDR) Salmonella in chicken meat sold in Metro Manila wet markets. This is a serious concern, as Salmonella infections can cause fever, diarrhea, and vomiting.
The study used whole genome sequencing to analyze Salmonella samples. The most common type was Salmonella Infantis. Many samples showed resistance to multiple antibiotics. Over 50 antibiotic resistance genes were found.
The researchers found that plasmids, small DNA pieces that spread resistance, were present in some Salmonella strains. This makes the spread of resistance even more concerning.
The team stressed the need for better surveillance of bacteria in poultry. They also called for stricter regulations on antibiotic use in farming. Infections from MDR Salmonella can be life-threatening, especially for vulnerable people.
The researchers warned of the risk of MDR Salmonella spreading in wet markets and homes. Cross-contamination is a significant concern. They recommended multi-sectoral policies to address the problem. This includes improving antibiotic use, increasing awareness of antibiotic resistance, and supporting research into new treatments. The study was funded by the Department of Agriculture.
