The Global Burden of Foodborne Diseases
Results for action

Food:
The good, the bad and the misreported –
Why we needed to estimate the burden of foodborne diseases
…and the under- and un-reported
What are "Foodborne Diseases"?
ingestion of contaminated food
prions and chemicals/toxins (inc
. aller ergens)
Myth No 1:
'Foodborne diseases are mostly a problem of developing countries' USA: 76 million cases
from pathogens alone each year
(Mead et al, Emerg Infec Dis, 1999)
Myth No 2:
'Foodborne diseases in rich countries are mostly travel-related'
United States and EU: In most countries majority of cases is domestically acquired
(CDC & European Food Standards Agency)
Myth No 3 – the convenient one:
'It's imported foods from poor countries (aka 'poor hygiene') that cause our foodborne diseases'
Rich countries have exported new foodborne diseases to poor countries: Salmonella enteritidis Salmonella typhimurium Dioxin BSE
Myth No 4:
'Foodborne diseases are getting less & less frequent' 335 newly emerging infectious diseases:
through food (~30%)
in agricultural or food industry"
antibiotics
Compounded by effects of climate change
Myth No 5:
'Foodborne diseases are mild, self-limited and short' 2.2 million deaths from diarrhoeal diseases each year world-wide
(World Health Organization, 2008)
USA: 5,000 deaths from foodborne illness from pathogens alone each year
(Mead et al, Emerg Infec Dis, 1999)
Campylobacter: Guillain Barré Syndrome Reactive arthritis Salmonella spp: Guillai ain B n Barré é Syndr ndrom
Reactive arthritis Septicaemia Meningitis Listeria: Meningitis Septicaemia Perinatal loss E.coli: Renal failure Pork tapeworm: Epilepsy Toxoplasma: Retinopathy Trichinella: Multi-organ failure Acrylamide: Cancer Arsenic: Cancer Aflatoxin: Cancer Lead: Mental retardation Dioxins: Cancer Allergens: Anaphylactic shock
Myth No 6 – the hopeful one:
' As a vegetarian I am less likely to get foodborne diseases'
Myth No 7 – the easy one:
'Governments hold the sole responsibility for making food safer'
Processing Storage Cooking Livestock Crops Seafood
Distribution Retail
Industrial emissions and effluents Sewage Vehicle emission Agricultural practices
Myth No 8 – the dangerous one:
'Food security is more important than food safety'
Food security without food safety can cause great harm
vulnerable to foodborne diseases & more likely to die
discarded in famine situations
Myth No 9 – the big one:
'Our food is perfectly safe'
How big is the burden of foodborne diseases?
Reported human cases
What we know from surveillance data What we need to know
Actual human disease burden Reported human cases
Myth No 10 – the understandable one:
'We can never estimate the burden of foodborne diseases' Yes, , we we can. an. And nd we we hav have. e.

WHO Initiative to Estimate the Global Burden of Foodborne Diseases
– Because information on burden of FBD from all causes is poor – Policy makers require information to assess effectiveness of prevention and interventions (incl. Codex) – Foster international development and global health security
– Estimation of morbidity, disability and mortality of FBD – Development of tools for countries to conduct BoD studies
– Global and regional report – Country Burden of Disease studies
