Seawater may look lovely – all those pretty blues and greens – but what you can’t see may make you feel a little sick.

Tiny fish eggs, crab larvae, and worms may look gross under the microscope, but it’s the unseen bacteria that lurk in every splash which could do you ill.

72 hours is the recommended time to avoid the surf after significant rainfall in populated areas, to lessen the chance of becoming sick from contact with e. coli or other disease agents.
