No, our AFA algae is a fresh water species of blue-green algae. (AFA is not seaweed from the ocean.)
As a standard testing protocol, our testing includes testing for Saxitoxins. Since 1995, we have never received a positive test result for Saxitoxin in any of our AFA algae products.
We thoroughly test every batch harvested, exceeding regulation standards, to ensure safety.

Saxitoxin, when ingested by humans, can cause (PSP) paralytic shellfish poisoning, which is primarily from sea water algae species.
