  1. ‘AMR- what can farmers do?’ • Rob Doyle • SSVI AMR Section DAFM • FAS Training 2019

  2. Antibiotic Resistant Infection

  3. What is AMR? • Antimicrobial resistance (AMR) is the ability of a microorganism (like bacteria, viruses, and some parasites) to grow/survive in the presence of an antimicrobial (such as antibiotics) that should be capable of killing it when given at the correct dose • Antibiotics are natural or synthetic substances that inhibit the growth of or destroy bacteria • As a result, standard treatments become ineffective, infections persist and may spread to others. • Bacteria can become multi-resistant • There are some infections that are not treatable with any available antibiotics

  4. Antibiotic Resistance vs Antibiotic Residues • Antibiotic residues are traces of antibiotics and associated metabolites that remain in meat and milk derived from animals that have been treated with antibiotics, with a violative level defined as one that is above the MRL. • Observing WP prevents residues entering food chain but has no effect on development of AMR. • Any use of antibiotics leads to AMR over time and reduces the effectiveness of antibiotics

  5. How does Resistance Develop?

  6. Selection Pressure

  7. Survival of the Fittest

  8. Replication of Resistant Strains

  9. Transfer of Resistance

  10. Transfer of Resistance

  11. What are CIAs? • WHO categorises certain antimicrobials used in human health as ‘critically important’. • The CIAs are further categorised into Highest Priority CIAs (HP-CIAs) • Drugs of last resort in human medicine when 1st line therapy fails • Strict Controls

  12. DAFM POLICY ON HP-CIAs • Advice on use: • Should; • NOT be used prophylactically • NOT be used as first line of treatment in animals. • ONLY be used when there are no effective alternative antimicrobials available for the respective target species and indication. • Be used based on culture and susceptibility testing

  13. What increases the risk of Resistance?

  14. Antimicrobial Resistance – Actions to keep antibiotics effective
