The densely-populated island of Luzon is home to over half of the Philippines’ population, many of whom consume shellfish on a regular basis. An international team of scientists has just confirmed the presence there of two species of Pseudo-nitzschia diatoms capable of producing a dangerous neurotoxin that can cause severe sickness and memory loss. Poetically described as “algae that live in glass houses,” diatoms are microscopic aquatic organisms that cover themselves in protective milk-colored silica shells. While most diatom species are harmless, half of the 58 known species from the genus Pseudo-nitzschia are notorious for producing domoic acid (DA).
