Randomized trial assesses antibiotic residues in meat and feed, suggesting risks for antimicrobial resistance.

The study aims to assess contamination levels of beef, pork, and animal feed with antibiotic residues in the Kostanay region.
Analyzed beef, pork, and feed samples for antibiotic residues
Conducted microbiological analysis on meat samples to identify bacterial species and resistance levels
Compared contamination levels across different types of animal feed
Detected antibiotic residues in beef, pork, and feed, remaining below maximum residue limits
Identified Escherichia coli and Staphylococcus aureus in meat samples, with moderate to high antimicrobial resistance
Highest resistance noted against tetracycline, streptomycin, and thiamphenicol

Shevchenko et al. (2026) studied this question.
