This systematic review and meta-analysis examined the prevalence of market-source pathogens in traditional food markets from 2000 to 2025, analyzing 247 studies across 41 countries. The global pooled prevalence of pathogens was found to be 15.32% (95% CI 13.96-16.80), with the highest rates in southeast Asia (23.09%).
Key findings
- Global pooled prevalence of market-source pathogens was 15.32% (95% CI 13.96-16.80).
- Bacterial pathogens had a pooled prevalence of 19.41% (95% CI 16.21-23.08).
- Fish and seafood markets showed the highest pooled prevalence at 37.87% (95% CI 26.05-51.33).
- Higher methodological quality was associated with lower reported prevalence.
Why it matters
Understanding the prevalence of pathogens in traditional food markets is crucial for public health, particularly in low- and middle-income countries where these markets are prevalent. This knowledge can inform risk assessments and guide interventions to reduce zoonotic and foodborne disease transmission.
