f saxitoxin, which affects the nervous systems of humans and animals alike. Since then, no further deaths of large numbers of sea turtles have been reported from El Salvador, although a similar sea turtle die-off was reported in Panama in early February. In El Salvador, the levels of toxins in shellfish have decreased but are high enough to maintain the ban on harvesting shellfish.

Red Tide events have become increasingly common around the world, causing significant impacts on wild marine animal populations, massive economic losses to shellfish producers, and occasionally human deaths. While the algal blooms are a natural occurrence, human wastes such as run-off containing fertilizers and sewage from urban areas have been postulated as triggers for these events.
