This document summarizes estimates from the World Health Organization on the global disease burden of foodborne illnesses in 2010. Some key points: - An estimated 48.4 million cases of foodborne illnesses occurred globally in 2010, with 48% attributed to food transmission. These resulted in 8.78 million disability-adjusted life years (DALYs). - Parasitic diseases accounted for 48.4 million cases and 8.78 million DALYs globally in 2010, with 76% of DALYs attributable to food transmission. - Enteric diseases caused by 21 agents resulted in 582 million foodborne illnesses globally in 2010, with children under 5 and those in low-income countries disproportionately affected.

DALY
Disability Adjusted Life Year
 YLL = years of life lost due to premature death
 Residual Life expectancy – Age of Death
 YLD = Equivalent Years lost due to disability
 Disability weight x duration
 DALY = YLL + YLD
 54 year old man
 Sudden death – loses 30 YLLs
 Epilepsy DW = 0.296
 loses 30*0.296 = 8.9 DALYs
 Acute febrile illness for 1 week – DW 0.2
 Loses 1/52 * 0.2 = 0.004 DALYs

• … suffer from 53% of all foodborne
illnesses
• … succumb to 75% of foodborne deaths
• … bear 72% of global foodborne DALYs

● WHO has launched the most comprehensive estimates
of the global burden of foodborne diseases to date
● These address the lack of data to support food safety policy
making
● Despite data gaps and other limitations, the results demonstrate
a considerable burden
● A large share of the burden is borne by children under
five years of age and those living in low-income countries
● Priority hazards differ between regions
● Control methods do exist for many hazards, and are linked to
economic development and effective food safety systems
● Hazards of global significance need novel control methods
