Our oceans are changing. A few weeks ago, the Woods Hole Oceanographic Institution hosted scientists at the first International Invasive Sea Squirt Conference. The group of species under discussion has invaded New England waters and has, among many other nasty acts, begun growing over our shellfish beds.
Now we find that the worst-on-record bloom of a one-celled organism called "red tide" has expanded throughout the Massachusetts and Cape Cod bays, pushed its way through the Cape Cod Canal and made it over to Martha's Vineyard -- and is possibly heading for Narragansett Bay and Long Island Sound. It has turned clams and mussels poisonous. Fish are dying, shellfish beds are closed and clam diggers are out of work.
"The dominance of one organism is characteristic of disruption," says George Woodwell, founder and director emeritus of the Woods Hole Research Center.
Our poor old ocean! Red tides are somewhat common, but not one this size.
The current plague, which may or may not disappear by July 4th, appears to have several causes.

Red tides are a natural ocurrence and happen pretty much every year. If you eat shellfish during red tide, you can die. Red tides are caused by plankton that turns red as it seeks sunlight. Creatures that eat the plankton, which in turn are eaten by humans, may or may not be poisonous, but if you eat such creatures during a red tide, you might die.
You can read all about red tides here: http://museum.gov.ns.ca/poison/redtide.htm
My opinion is to not eat any shellfish or other infected creatures during redtide. Symtoms vary depending on the toxin, but range from horrible gastrointestinal symptoms, to brain damage, to paralysis, to death. Nasty.
Eating shellfish when there are warnings against it is plain stupid. And the symptoms, if you live through them, are awful.
