In a study financed by the Univ of Hawaii, when a "No Swimming" sign is posted for contamination, people tend to stay on the sand--but the sand can be 10 to 100 times ickier than the water.
Sewage-polluted coastal waters can lead to stomachaches, diarrhea and rashes.
To see how long these pesky microbes stick around, the researchers created microcosms of seawater and sewage and the communities of microbes degraded much more slowly on the sand.
So--I guess--don't let babies eat sand, don't put sandwiches down on the sand, shower after the beach, pack some sanitizer--or just figure it will boost your immunity.
Make sharks look good, doesn't it?
