I manage the operation and delivery of the regulatory monitoring programme for biotoxin-producing phytoplankton, conducted by SAMS on behalf of Food Standards Scotland. We report the concentration of potentially harmful phytoplankton from around 40 sites every week.
Some phytoplankton can produce toxins that accumulate in bivalve molluscs, which leads to human illness if the shellfish are consumed. Monitoring the development of phytoplankton blooms can therefore act as an early warning system for toxic events.
