Organic spirulina

SPIRULINA is a single-celled microorganism that closely resembles a bacterium. Its spiral-shaped filaments are rich in plant pigments such as chlorophyll, phycocyanin and beta-carotene. Spirulina turns the lakes and ponds where it grows a dark-blue green.  

Harvesting your own spirulina is not advisable as coastal and aquatic colonies of the algae may be contaminated with industrial waste or sewage. Cultivation of organic spirulina involves locations away from industrial pollution (for example, a remote hamlet), where there is no contamination. There should also be no other agricultural activity in the area (to avoid contamination with pesticides, herbicides and fertilisers).
