Although it can be fatal to fish, it is harmless to humans in the water. Where it becomes a problem for humans is after it washes on the beach and dries. At that point, it releases an aerosol, which can cause allergy-like reactions such as itchy eyes, nausea and sneezing. These symptoms, coupled with piles of dead fish, has kept visitors away from South Texas beaches for months. However, since the weather has begun to cool slightly, the bloom has waned to the point of not even being noticeable. As fall wears on, the tide should disappear completely. So, after months of waiting, it is once again pleasant to visit the beach along the South Texas coast.
