Implication

Analysis reveals 20.1% prevalence of mcr-1-positive Salmonella in pork, highlighting a concerning rise in colistin resistance and multidrug resistance.

Key Points

Colistin-resistant Salmonella isolates were found in 2.2% of samples from pork products, indicating significant resistance issues.
A total of 92 Salmonella isolates were recovered, with high resistance rates of 90.2% to tetracycline and 58.7% showing multidrug resistance.
Genomic analysis identified novel resistance regions in isolates, linked to food chain transmission, underscoring health risks.
These findings emphasize the urgent need for enhanced surveillance in livestock to combat antimicrobial resistance.
