Burden of foodborne disease due to bacterial hazards associated with beef, dairy, poultry meat, and vegetables in Ethiopia and Burkina Faso, 2017
Foodborne disease is a significant global health problem, with low- and middle-income countries disproportionately affected. Given that most fresh animal and vegetable foods in these countries are bought in informal food systems, much the burden of foodborne disease here is also linked to informal markets.
Developing estimates of the national burden of foodborne disease and attribution to specific food products will inform decision-makers about the size of the problem and motivate action to mitigate risks and prevent illness.
A new study published in Frontiers in Sustainable Food Systems (Nov 2022) provides estimates for the burden of foodborne disease caused by selected hazards in Burkina Faso and Ethiopia in 2017 and attribution to specific foods.
Country-specific estimates of the burden of disease in 2010 for Campylobacter spp., enterotoxigenic Escherichia coli, Shiga-toxin producing E. coli and non-typhoidal Salmonella enterica were obtained from the World Health Organization (WHO) and updated to 2017 using data from the Global Burden of Disease study.
Attribution data obtained from WHO were complemented with a dedicated Structured Expert Judgement study to estimate the burden attributable to specific foods.
The burden of foodborne disease in the two countries in 2010 was largely similar to the burden in the region except for higher mortality and disability-adjusted life years (DALYs) due to Salmonella in Burkina Faso. In both countries, Campylobacter caused the largest number of cases, while Salmonella caused the largest number of deaths and DALYs.
In Burkina Faso, the burden of Campylobacter and enterotoxigenic E. coli increased from 2010 to 2017, while the burden of Salmonella decreased. In Ethiopia, the burden of all hazards decreased. Mortality decreased relative to incidence in both countries.
In both countries, the burden of poultry meat in DALYs was larger than the burden of vegetables. In Ethiopia, the burdens of beef and dairy were similar, and somewhat lower than the burden of vegetables.
