Food poisoning can affect anyone, but risk and severity vary widely by group, pathogen, and setting. WHO estimates unsafe food leads to 600 million illnesses and 420,000 deaths annually worldwide, with major burdens also documented in the U.S. and EU. Here you’ll explore who is most vulnerable, common causes like norovirus, Salmonella, Campylobacter, and E. coli, typical symptoms, and practical prevention steps—from hand hygiene to safe refrigeration and cooking temperatures.
Key Takeaways
- Pregnant women: 20% miscarriage risk from Listeria per CDC
- Elderly over 65: 10x higher hospitalization rate per CDC
- Children <5 years: 40% of global disease burden per WHO
- Norovirus causes 685 million cases worldwide annually per WHO
- Salmonella responsible for 93.8 million illnesses globally each year
- Campylobacter jejuni leads to 1.5 million US cases yearly per CDC
- 48 million US cases cost $15.5 billion yearly per CDC
- Global foodborne diseases economic loss $110 billion annually per WHO
- US Salmonella outbreaks cost $2.3 billion per year per CDC
- The World Health Organization estimates that unsafe food causes 600 million illnesses and 420,000 deaths annually worldwide
