Phycotoxins

Phycotoxins are toxic substances produced by certain microalgae species, known as phytoplankton. These toxins can contaminate marine organisms like shellfish and fish, which accumulate them by feeding on contaminated phytoplankton. When consumed by humans or other animals, these contaminated marine products pose health risks. Phycotoxins, such as brevetoxins, okadaic acids, and domoic acids, can cause food poisoning, affecting the nervous and digestive systems, even leading to severe syndromes. Red tides, linked to phytoplankton proliferations, are often associated with these toxins. Environmental conditions, like temperature and nutrients, favor these red tides. Monitoring phycotoxins in fishing areas, along with warnings and temporary bans during high concentrations, are crucial measures to minimize health risks associated with these marine toxins.
