Pseudo-nitzschia

Pseudo-nitzschia is a type of tiny, single-celled algae (diatoms) found in marine environments. During certain conditions, it can multiply rapidly, forming harmful algal blooms. These blooms produce domoic acid, a potent toxin that accumulates in shellfish and fish. When humans consume contaminated seafood, it can cause amnesic shellfish poisoning, leading to health issues like memory loss and neurological problems. Pseudo-nitzschia is an important species to monitor, as its blooms pose risks to both marine life and public health.
