Topic: Economics of animal-rearing
Q5. Discuss how intensive livestock production influences the evolution and transmission of zoonotic pathogens. Examine its implications for public health. Suggest measures to build resilient food production systems. (15 M)
Difficulty Level: Medium
Reference: DTE
Why the question
The growing evidence linking industrial livestock production, zoonotic diseases and antimicrobial resistance (AMR) has brought food safety and the One Health approach to the forefront of global public health discourse.
Key Demand of the question
The question requires explaining how intensive livestock production drives the evolution and transmission of zoonotic pathogens, examining its implications for public health, and suggesting measures for building resilient and safe food production systems.
Structure of the Answer:
Introduction
Briefly introduce the One Health concept or highlight the growing global burden of zoonotic diseases and foodborne infections.
Body
- Influence on pathogen evolution and transmission: Explain the mechanisms through which intensive livestock production promotes pathogen emergence and spread.
- Implications for public health: Highlight the consequences for food safety, disease burden, AMR and health systems.
- Measures for resilient food production systems: Suggest policy, technological and institutional measures for sustainable and safe livestock production.
Conclusion
Conclude by emphasising that resilient food systems require integrating animal, human and environmental health through a One Health approach.
