🟢 Strong Evidence
Children under five years face nearly three times the risk of illness from contaminated food compared to older age groups, according to new estimates released by the World Health Organization. The WHO’s latest data reveals that unsafe food causes 866 million illnesses and 1.5 million deaths globally each year, with the youngest populations bearing a disproportionate burden.
Key takeaways
- Children under 5 face 3x higher risk of foodborne illness than older populations
- Unsafe food causes 866 million illnesses globally per year
- Foodborne diseases result in 1.5 million annual deaths worldwide

Children Bear Disproportionate Health Burden
The World Health Organization’s analysis reveals that young children face an outsized risk from foodborne pathogens due to their developing immune systems and smaller body size. The data shows children under five experience illness rates nearly triple those of older age groups when exposed to contaminated food sources.
This vulnerability stems from multiple factors, including immature gut microbiomes and higher food consumption relative to body weight. The WHO emphasizes that proper food safety measures could prevent the majority of these preventable illnesses and deaths among vulnerable populations.
Global Scale of Foodborne Disease Challenge
The WHO’s comprehensive assessment documents the massive global health impact of unsafe food practices. With 866 million people falling ill annually from contaminated food, foodborne diseases represent one of the world’s most pressing public health challenges, according to the WHO’s burden estimation program.
The 1.5 million annual deaths attributed to unsafe food consumption highlight the urgent need for improved food safety systems worldwide. These figures underscore how preventable deaths continue to occur due to inadequate food handling, preparation, and storage practices across both developed and developing nations.
Prevention Strategies Show Promise
The WHO emphasizes that the majority of foodborne illnesses and deaths are entirely preventable through proper food safety measures. Key interventions include improved hygiene practices, better cold chain management, and enhanced food safety regulations, particularly in settings where young children consume meals.
For healthcare systems, these findings highlight the importance of strengthening surveillance systems to track foodborne disease outbreaks and implementing targeted prevention programs. The data supports increased investment in food safety policies and public health infrastructure to protect the most vulnerable populations.
Children under five years face almost three times the risk of illness from unsafe food compared to older children and adults, representing a critical public health vulnerability.

What this means
Frequently asked questions
Why are young children at higher risk for foodborne illness?
Children under five have developing immune systems, immature gut microbiomes, and consume more food relative to their body weight, making them more susceptible to foodborne pathogens.
What are the most common sources of foodborne illness?
Contaminated foods include improperly stored dairy products, undercooked meat and poultry, unwashed fruits and vegetables, and foods prepared with poor hygiene practices.
How can families prevent foodborne illness?
Key prevention measures include proper handwashing, cooking foods to safe temperatures, refrigerating perishables promptly, and avoiding cross-contamination between raw and cooked foods.
The WHO’s findings underscore the critical importance of global food safety initiatives, particularly those targeting protection of children. As healthcare systems worldwide grapple with preventable disease burdens, these data provide compelling evidence for increased investment in comprehensive food safety programs that can save lives and reduce healthcare costs.
