Mahogany Tide: Toxic plankton invades Mobile Bay — Known to cause death and illness in humans after consuming poisoned shellfish (PHOTOS)


Mobile Bay, Mobile, Alabama, Kathy Looney, March 3, 2011:

This morning I spoke with Mark O. with ADEM (Alabama Department of Environmental Management) regarding the every day event that is occuring in Mobile Bay with the brown foam.  He said that he is aware of it and it is MAHOGANY TIDE (Prorocentrum Minimum) a form of algae, it's similar to Red Tide, and he has had many reports/calls and it's as far in as Dog River. [...]

Mark stated that he has conducted tests all over the Bay and wanted me to know there have been NO toxic effects observed.

BUT..... in the emails that were forwarded to me from Mark, there was a website  'Marine Species Identification Portal' and it states:

'Species Overview: Prorocentrum minimum is an armoured, marine, planktonic, bloom-forming dinoflagellate. ...

P. minimum is a toxic species; it produces venerupin (hepatotoxin) which has caused shellfish poisoning resulting in gastrointestinal illnesses in humans and a number of deaths. This species is also responsible for shellfish kills in Japan and the Gulf of Mexico, Florida (Nakazima, 1965,Nakazima, 1968, Okaichi and Imatomi, 1979, Tangen, 1983, Shimizu, 1987, Smith, 1975, Steidinger and Tangen, 1996).'

[...] I began observing the foam (Mahogany Tide) the first week of January 2011.  So it has been going on for over 8 weeks now (not two) and if it 'ramps' up when the waters warm up, that won't be until mid-May, another 12+ weeks!  So, if people don't believe that the oil has affected the seafood in the Gulf of Mexico - I hope that they realize that this has and will continue to!
