Health opportunities and challenges in the livestock sector
linked to One Health
ILRI/Stevie Mann
• Nutrition, health and food security
• BUT animal-human/emerging diseases and
unsafe foods need to be addressed and
overconsumption is often associated with
obesity and non-communicable diseases
• Environmental health and biodiversity
• BUT pollution, land/water degradation
need to be reduced

9. 9
Lessons learnt: Informal markets, food safety, wild meat
Informal markets provide an essential source
of food and income for millions of people with
access to animal source foods that is often
safer than the food in supermarkets in LMICs
Nudge kits delivered
What is the incentive for changes?

Lessons learnt: Antimicrobial resistance
Challenges in many parts of Africa
• High prevalence of infectious disease
(limited information in humans and
little to none in animals)
• Access to veterinary services and
diagnostic capacity
• Little knowledge among users and
distributors about the disease and
products
• Lack of alternatives – vaccines,
improved biosecurity and biosafety
measures
• Sub-standard or counterfeit antibiotics
available
• Easy access to antimicrobials

12. 12
Lessons learnt: Cysticercosis - Neglected tropical disease
Nuerocysticercosis causes
appoximately 30% of epilepsy in
humans in T. solium endemic regions
The disease is estimated to cause
around 5 million human cases and
50,000 human deaths each year
The first ever licensed vaccine became
available in India at the end of 2016 at
USD 1 for 2 doses to vaccinate a pig

Lessons learnt: Rift Valley fever - Zoonosis
Infographics Jenner Institute
Risk and introduction of Rift Valley fever into the
European Union (EU) is significant given the increased
trade of animals and presence of vectors in EU

One Health is an integrated, unifying approach that aims to sustainably balance and
optimize the health of people, animals and ecosystems.

ILRI One Health strategy
A holistic approach to preventing pandemics/epidemics and other
microbial threats from animals and the environment
Vision
To improve the lives, livelihoods and well-being of people in the
global south by building healthy, sustainable and resilient systems at
the intersection of humans, animals and the environment.
Key thematic areas
• Epidemics and pandemics caused by (re)-emerging viruses
• Endemic zoonoses
• Foodborne diseases
• Antimicrobial resistance

Preventing the next pandemic
Seven major anthropogenic
drivers of zoonotic disease
emergence
1. Increasing demand for
animal protein
2. Unsustainable agricultural
intensification
3. Increased use and
exploitation of wildlife
4. Unsustainable utilization
of natural resources
5. Travel and transportation
6. Changes in food supply
chains

28. Policy impact: translational research for interventions in
modernizing food system
• CGIAR/ILRI niche: Risk assessment and
policy/regulatory analysis for fresh foods
in domestic markets
• World Bank convened overall support to
government: ILRI-led technical work
• Government took up the World Bank
report to improve food safety in major
cities in Vietnam

Key messages
• Importance of livestock for food and nutrition security; livestock sector is fast
growing.
• Health challenges linked to animal and farmed wildlife.
• Capacity building and operationalization of One Health in the global south
need to be done at regional, national and local levels.
• One Health research and development agenda should cover a wide spectrum
from research, capacity development and stakeholder engagement across
animal, human and environment health sectors to prepare, detect and
respond.
