| Abstract |
Three types of toxins have been recorded in southern Chile: paralytic shellfish poisoning (PSP), lipophilic shellfish toxins or diarrheic shellfish poisoning (DSP), and amnesic shellfish poisoning (ASP). The paralytic and lipophilic toxins have caused serious consequences to public health and the local economy. The amnesic toxin is found in certain geographic areas and is generally below the permissible limit for human consumption. The first toxic events involving the paralytic toxin occurred at the beginning of the 1970s in the Magallanes Region, stretching northward in the 1990s and 2000s. In 2002, the first toxic PSP event was recorded in the Los Lagos Region, the area with the greatest development of bivalve farming; shellfish coming from Quellón (Chiloé Island, Chile)
were found to have up to 29.544 μg STX eq. 100 g-1. This inflicted approximately 60 individuals and caused one death. In 2006, a second, milder event was recorded, with values of 600 μg STX eq. 100 g-1. At present, a coordinated monitoring programme between the Instituto de Fomento Pesquero (Institute for Fishery Development) and the Regional Ministerial Health Office for each region is being run in the three southernmost regions of Chile. This programme analyzes toxins, phytoplankton and environmental variables at 151 stations. A second monitoring programme associated with the Programa de Sanidad de Moluscos Bivalvos (PSMB; Bivalve Mollusc Health Programme) certifies the harvesting sites. This latter programme is under the sole responsibility of the local shellfish farmers. |
