The VIIIth International Conference on Toxic Cyanobacteria (ICTC), held in September 2010 Istanbul, Turkey, included a session in which scientists and regulators reported approaches to controlling hazards from toxic cyanobacteria implemented or discussed in their country, as well as awareness of the issue. Presentations demonstrated substantial recent progress in the per-ception of cyanotoxins as risk to human health and in risk management, particularly when com-paring the current status of regulatory approaches to that reported six years earlier at the VIth ICTC in Bergen, Norway. Again, differences and similarities between countries in the approach-es to managing this risk proved very much worth sharing, and it became clear that the booklet of regulatory approaches compiled after the Bergen conference should be updated, particularly with contributions from countries who have implemented regulatory approaches since then.
