After the finding of 550 death birds and 4 marine mamals in the beaches of San Felipe, the Mexican government agency in charge of the environment “Profepa” sponsored the evaluation and analysis of our coastal waters, through the scientific work performed by the agencies SENAISCA and ISESALUD.
They dissected the dead animals and through several biological and micro biological tests they come up with the following result: They found high doses of Saxitoxin, a neurotoxin identified as the main cause of the current situation.
According to Wikipedia “Detection of Saxitoxin in shellfish such as mussels, clams and scallops frequently leads to closures of commercial and recreational shellfish harvesting, especially in California, Oregon, Washington, and New England.”
Also “Saxitoxin (STX) is the best-known as paralytic shellﬁsh toxin (PST), the ultimate source of STX is still uncertain. In the United States, paralytic shellfish poisoning is limited to New England and the West Coast. The dinoflagellate Pyrodinium bahamense is the source of STX found in Florida. Recent research shows the detection of STX in the skin, muscle, viscera, and gonads of “Indian River Lagoon” southern puffer fish, with the highest concentration (22,104 µg STX eq/100 g tissue) measured in the ovaries. Even after a year of captivity, the skin mucus remained highly toxic. The various concentrations in puffer fish from the United States are similar to those found in the Philippines, Thailand, Japan, and South American countries.”
The current condition of the San Felipe coast line is being defined as a RED TIDE with strong influences of Saxitoxin.
The latest known report from Profepa is from January 16. Where they clearly mention that the current prohibition on consumption of local fish and seafood will continue until further notice.
If you follow the authorities advice, you can avoid being paralyzed with a Saxitosin posoning condition which in some cases can also lead to death.
