Water- and food-borne diseases (2017)


  • It is not possible to assess whether past climate change has already affected water- and food-borne diseases in Europe, but the sensitivity of pathogens to climate factors suggest that climate change could be having effects on these diseases.
  • The number of vibriosis infections, which can be life-threatening, has increased substantially in Baltic Sea states since 1980. This increase has been linked to observed increases in sea surface temperature, which has improved environmental conditions for Vibrio species blooms in marine waters. The unprecedented number of vibriosis infections in 2014 has been attributed to the unprecedented 2014 heat wave in the Baltic region.
  • Increased temperatures could increase the risk of salmonellosis.
  • The risk of campylobacteriosis and cryptosporidiosis could increase in those regions where precipitation or extreme flooding is projected to increase.
  • Climate change can have an impact on food safety hazards throughout the food chain.
