I have said for years that Klamath Lake algae should not beconsumed. It is an area of intense agricultural runoff and is a polluted lake. This algae, which is known as Klamath Lake blue-green algae (aphanizomenon flos-aquae, AFA) is also quite toxic. Actually, Cyanobacteria is not an algae. In recently published reports researchers have demonstrated conclusively that I am indeed correct about this issue and that AFA should be avoided. In fact, AFA is the bane of many lakes around the world where scientists and governments have fought long battles to rid it from the environment due to its incredible destructive power.
“Researchers have warned against the sale of organic algae supplements containing the algae strain Aphanizomenon flos-aquae after a samples of every commercially available supplement available in the country were found to contain potentially dangerous toxins”
“The analysis for the presence of cyanobacterial toxins (MCs, nodularins, saxitoxins, anatoxin-a and cylindrospermopsin) encompassed only algae dietary supplements marketed in Germany and thus only the three main types of algae generally used for the production of dietary supplements, i.e. Aph. flos-aquae, Spirulina and Chlorella,” said the researchers, writing in Toxicology and Applied Pharmacology.”
There is nothing in AFA that cannot be found in Spirulina in the way of nutrients since both of them are Cyanobacteria. If AFA it a truly healthy food then they should cultivate it in a controlled environment and ponds the way Chlorella and Spirulina are grown, and not harvested from a polluted lake.
“The researchers said their analysis ‘clearly demonstrated’ that a high proportion of the algae dietary supplements available on the German market “is contaminated with considerable, but varying amounts of MCs. “Moreover, cytotoxicity analyses suggest that additional components are present that have the potential to induce fulminant adverse effects in consumers,”
“In light of the findings, the distribution and commercial sale of Aph. flos-aquae products, whether pure or mixed formulations, for human consumption appear highly questionable,” Dietrich and his colleagues warned.
What more evidence do you need? AFA is bad news. Don’t eat it. Stick with spirulina if you want to consume a blue green algae (cynobacteria).
