It’s that time of year in South Africa again – temperatures have warmed up and so have nutrient-enriched dams and ponds.  Many have developed algal blooms that could be toxic, so beware!

Droplets contains lots of useful information about blue-green algae and their toxins.  In the USA, the Centre for Disease Control has produced a very useful facts sheet that provides all the essential background.  South Africa does not have any resources focussed on algal blooms (!) or where to get help should one develop problems after being in contact with toxic algae.  DH Environmental Consulting can be approached for guidance and we have ability for rapid on-site toxin testing and algal identification.  Algal blooms pose a threat  to humans, pets and livestock.  They should not be underestimated.

We will shortly be releasing an App that will enable users to send us details of algal blooms they come across so that we can build a geographic database of bloom occurrence.  In the meantime you are welcome to email us information and photographs of what you saw, to info@dhec.co.za

Merry Xmas!
