MANILA, Philippines — Scientists have discovered two diatoms in shellfish farms in Luzon that can cause severe sickness and amnesia. “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,” a statement by Ateneo de Manila Research Communications read. The statement added that a person who consumes domoic acid produced by Pseudo-nitzschia “may experience vomiting, nausea, diarrhea, and abdominal cramps” and memory permanent loss of short-term memory.
Further, scientists from the Ateneo de Manila University and Universiti Malaysia Sarawak conducted a study on the physical and genetic characteristics of diatoms in water samples of shellfish farms in Bacoor Bay and Pagbilao Bay in Luzon.

The researchers then confirmed the presence of Pseudo-nitzschia pungens and Pseudo-nitzschia brasiliana in the samples taken.

They also emphasized the importance of monitoring harmful algal blooms or “red tide” where domoic acid can grow in filter-feeding shellfish like mussels and claims.
