Fishermen in the Malaga area have had a bad start to 2008 as a “red tide” has forced the authorities to close down the shellfish beds between Nerja and Sabinillas. The decision has been made due to the proximity of a large concentration of the Gymnodium catenatum algae which contain a toxin that causes PSP (paralytic shellfish poisoning) that can lead to episodes of paralysis and even death in human beings. The toxin is absorbed by the shellfish which store it in their organisms without any noticeable change. The algae make the sea water look red, hence the name “red tide”.
If consumed by humans the toxin can cause tingling, heat and numbness in the lips, tongue, face, neck, fingers and toes, as well as nausea, dizziness and breathing difficulties. In the worst cases it can lead to the paralysis of the body and brain, causing death.
As a preventative measure, and following EU directives, biologists from the regional fisheries department analyse the water for signs of this and other potentially dangerous toxins every week.
The closure of the shellfish beds affects some 150 vessels and 200 crew members who will receive aid if the measure lasts for more than 21 days.
Meanwhile all the mussels, clams, scallops and other molluscs in Malaga’s markets and restaurants will have to come from ports outside the province.
