This document discusses the large burden that agriculture imposes on human health through emerging diseases, foodborne diseases, zoonoses, and malnutrition. It notes that agriculture is associated with 3 million deaths per year globally, with zoonoses and foodborne diseases alone killing 2.2 million people annually. The poor are most affected by these diseases. Agricultural solutions exist for controlling many agriculture-associated diseases, with benefits often outweighing costs. Improving food safety practices in informal markets through training and certification programs can significantly improve health outcomes.

Tackling food-borne diseases and zoonoses through agriculture
- 1. Healthy lives: Tackling food-borne diseases and zoonoses Delia Grace, Kristina Roesel, Bernard Bett, Fred Unger Tropentag 2014: Bridging the gap between increasing knowledge and decreasing resources Prague, Czech Republic, 17−19 September 2014
- 2. Towards evidence and impact at scale Agriculture research and human health – Evidence: Mapping, measuring, targeting – Technology: diagnostics, vaccines, decision support – Impact: Safe food in wet markets
- 3. Agriculture imposes large burdens on human health Emerging Food borne Malnutrition Zoonoses Malaria Three million deaths a year are agriculture associated One quarter of all deaths from infection are agriculture associated Almost all of these occur in developing countries
- 4. Zoonoses and FBD kill 2.2 million a year • 2.4 billion people sick • 2.2 million people dead • more than 1 in 7 animals affected Zoonoses & FBD cost $84 billion a year • $9 billion in lost productivity • $25 billion in animal mortality • $50 billion in human health costs Agriculture imposes large burdens on human health
- 5. The poor are most affected by zoonoses and FBD
- 6. 6 Emerging infectious diseases 1940-2012 Zoonoses make up 75% of EIDs and cost 6.7 billion a year
- 7. Agricultural solutions work for most agriculture associated diseases For 70% of ag. associated diseases proven and cost effective agricultural solutions exist Emerging Food borne Zoonoses Malaria Malnutrition
- 8. Most zoonoses and food-borne disease require agricultural solutions Controlling zoonoses in animal reservoirs (n=13) – On average $6 benefit for $1 cost 8 Ex ante 5.0$ gain for 1$ cost Ex post 6.6$ gain for 1$ cost Poor countries 3.7$ gain for 1$ cost Rich countries 7.4$ gain for 1$ cost
- 9. Emerging diseases are difficult to prevent but timely responses reduce impacts • Surveillance and response in animal hosts can reduce costs by 90% Adapted from IOM 2009
- 10. ILRI: better lives through livestock 10
- 11. Evidence for ag. associated diseases 11
- 12. Technologies for ag. associated diseases 12 • Disease resistant animals • Vaccines • Rapid diagnostics • Biocontrol for aflatoxins
- 13. Impact on ag. Associated diseases • Food-borne disease is a major cause of diarrhea • Most food is due to microbes in perishable foods • Most perishables are sold in informal markets • Workers in informal markets are untrained, often harassed, and have few incentives for sselling safe food
- 14. • Branding & certification of milk vendors in Kenya & Guwahti, Assam led to improved milk safety. • It benefited the national economy by $33 million per year in Kenyan and $6 million in Assam • 70% of traders in Assam and 24% in Kenya are currently registered • 6 milllion consumers in Kenya and 1.5 million in Assam are benefiting from safer milk
