Onderstaand informatie die ik opgezocht heb voor wat betreft de discussie of deze algen uit het Klamath meer nu wel of niet giftig zijn.

Original rumors linking the Klamath Lake variety to BMAA contamination began to circulate many years ago. These claims however were based on AFA toxin-producing strains, such as Aphanizomenon gracile, found in Germany and Poland. In this research at least one of these strains of Aphanizomenon flos-aquae labeled as toxic has been shown to have been misidentified. This is according to an update by the Oregon Health Authority and their Oregon Harmful Algae Bloom Surveillance Program.

Voor wat betreft de discussie of dit een schoon product is zie link uitleg en link.
All suppliers are highly skilled at monitoring AFA blue-green algae through its various growth cycles to ensure it is not contaminated with other species, like Microcystis aeruginosa. Moreover, elaborate micro-filtration systems are also in place to make sure the algae is free of contaminants.
As one of the company's we contacted put it:
"The entire AFA industry has always placed safety and purity at the top of the priority list. Indeed, it would have ended the industry long ago if anything less than that was the case."
The AFA supplements we recommend are now actually USDA Certified Organic and/or Certified Organic by the Oregon Tilth and undergo appropriate quality controls, extensive filtration processing and thorough testing for possible contaminants.
The EPA's (U.S. Environmental Protection Agency) "Drinking Water Health Advisory for Microcystins" is 1.6 micrograms per liter for school-age children through adults. The Oregon state limit for microcystins is 1µg/L microcystin-LR or 1 part per million for adults.

Is AFA a Source of BMAA or Other Cyanotoxins?
BMAA, or β-Methylamino-L-alanine, is a known neurotoxin that is produced by cyanobacteria species. It has been found in tap water, marine fish and is especially concentrated in shellfish.
Anytime you're dealing with wild water systems that can grow cyanobacteria, there is usually a potential risk that substances like BMAA and other cyanotoxins like cylindrospermopsin, anatoxin-a and saxitoxin can be produced when algal blooms occur.
In our research, however, we found that all suppliers contacted had NEVER had any experience with BMAA contamination, with results coming up "non-detectable" for this toxin every time tested.
