Overview

Cross-sectional study found fecal carriage of antimicrobial-resistant bacteria in dairy farm milkers, indicating food safety and public health risks.

Key Points

  • Assess the fecal carriage of carbapenemase-producing E. coli and Klebsiella spp. among dairy farm milkers in Northern Ethiopia.
  • Cross-sectional study involving 178 dairy farm milkers
  • Collected stool samples for analysis
  • Identified E. coli and Klebsiella spp. using bacteriological methods
  • Determined antimicrobial susceptibility using the Kirby–Bauer method
  • Used Firth’s penalized logistic regression to identify associated factors
  • E. coli and Klebsiella spp. isolated from 68% and 9.5% of participants, respectively
  • Carbapenemase-producing isolates detected in 3.4% of milkers, all multidrug resistant
  • Recent diarrhea and raw milk consumption identified as significant risk factors for fecal carriage
