Leading causes of poor health in developed and developing countries
• Measured as disability-adjusted life year (DALY)
• DALY is a measure of overall disease burden, expressed as the number of years lost due to ill-health, disability or early death.

Developed world
• Over 20 years the leading causes of poor health remained the same
• Non-infectious diseases• The leading cause of illness have been cardio-
vascular disease– Diet and sedentary lifestyle are risk factors

Developing world
• Over 20 years the leading cause of poor health remained the same
• Infectious diseases• First rank is respiratory infections– Mostly vaccine-preventable infections
• Second rank is diarrheal diseases – Poor sanitation and food safety standards– Zoonotic pathogens
• Cardio-vascular illness is creeping up the list

Concerns regarding animal-source foods in Ethiopia
• Low level of consumption of animal-source foods– Contribute to protein-energy malnutrition
• Presence of hazards in animal-source foods– Biological hazards (food-borne pathogens)– Chemical hazards (aflatoxins, drug residues)
• Risky practices at all levels along the value chainsPhoto credits: Tamsin Dewe, Elias Walelign, the Compass Edge

ILRI food safety work in Ethiopia
• Biological hazard risk assessment targeting foodborne pathogens in small ruminants– In slaughterhouses:• E coli 0157, Salmonella and Campylobacter in meat• Survey on health status of sheep and goats presented
for slaughter
– Rural smallholder producers:• Coliforms, E coli 0157 and Listeria monocytogenes in
goat milk and goat milk products

ILRI food safety work in Ethiopia
• Chemical hazard risk assessment targeting aflatoxins in dairy and poultry food chains

ILRI food safety work in Ethiopia
• Training and intervention– Hands-on training for meat inspectors on pre-and-
post harvest practices of small ruminants– Training for rural goat milk producers/processors on
good manufacturing practices

Questions to consider
• Will the current trends in disease burden continue for the foreseeable future?
• How does agriculture influence these trends?– Particularly zoonotic agents of diarrheal illness in
the developing world• What can we as livestock researchers do about
it?
