Abstract
• Toxin producing phytoplankton, pathogenic vibrios (bacteria commonly found in low salinity water) and noroviruses all have the potential to impact human health. • The relationship between climate change and toxin producing phytoplankton is complex. Considerable unknowns remain about how climate change will impact this part of the plankton community and confidence in predicting these impacts in UK waters remains low. • A recent study in Scotland has shown short term weather events as well as wind mediated transport of offshore phytoplankton populations can influence the toxicity of coastal shellfish. This highlights the requirement for long term data sets to identify the impacts of climate change from shorter term seasonal and interannual variability. • Emerging evidence from peer-reviewed scientific studies has suggested that increasing seawater temperatures and extreme weather events such as heatwaves and extreme precipitation, drive the abundance of pathogenic vibrios in the environment. A recent spate of reported infections in Northern Europe underlines these observations. Climate warming in the region may therefore increase human infections.
