Antimicrobial residues and resistant bacteria in the Indian dairy value chain

National Dairy Research Institute 6. Indian Veterinary Research Institute Antibiotics in the Indian dairy value chain A major concern in India is the overuse and misuse of antibiotics both in the human and animal sector due to the unregulated access. Previous studies have shown that it is common with antibiotic residues in dairy products, and mastitis bacteria are often found to be resistant to one or more classes of antibiotics. The objectives of this study was to: • Assess knowledge and practices regarding antibiotic use among dairy farmers in the states Haryana and Assam • Understand the pattern of antimicrobial resistant bacteria in bulk milk at farm level • Detect antibiotic residues in the milk aimed at consumption Pictures Conclusions • Farmers have too low knowledge about antibiotics to be able to use it appropriately • Antibiotic resistant bacteria in milk may pose a serious public health threat Johanna Lindahl J.Lindahl@cgiar.org ● Box 30709 Nairobi Kenya ● +254 20 422 3000 298 Kim Ma Street, Ba Dinh District, Hanoi ● ilri.org This document is licensed for use under the Creative Commons Attribution 4.0 International Licence. February 2019 Methods ✓ 3 districts in each state, 80 households per district ✓ Questionnaire on knowledge and practices ✓ One bulk milk sample per household ✓ Gram negative and positive bacteria cultured and tested for resistance genes ✓ Antibiotic residues evaluated using quantitative rapid tests ILRI thanks all donors and organizations which globally support its work through their contributions to the CGIAR system 0 10 20 30 40 50 60 Assam above Assam below Assam negative Haryana above Haryana below Haryana negative The antibiotics detected in the 48 samples positive for residues, Below or above the maximum residue limits Gram positives All isolates having resistance 25 MecA genes detected 2 MecC genes detected Gram negatives 173 out of 236 isolates resistant Results ➢ Farmers unaware about what antibiotics are or what withdrawal periods are ➢ Farmers seldom know what medicines the animals are treated with 0 50 100 150 200 250 300 Producers perception on use of antibiotics/medicine Disagree Agree Don't know
