Another potential source of illness includes some types of cyanobacteria that form algal “blooms” (discolored water) and the toxins they produce. When people are exposed to cyanotoxins, they may have hay fever-like symptoms, skin rashes, sore throat, cough, nausea, vomiting, diarrhea, or even kidney or liver damage.
Vibrio bacteria risksVibrio bacteria naturally occur in some coastal waters and reach higher concentrations when water temperatures are warmer, between May and October, according to the US Centers for Disease Control and Prevention.
Marine beaches also contain higher levels of Firmicutes, aerobic Gram-positive bacteria commonly found in the human gut, and Planctomycetes, a phylum of bacteria that may have beneficial relationships with marine algae.

When it comes to walking along the shore, our bodies need to compensate for a number of challenges: Typically, we need to trek through dry, loosely-packed sand before making it to the beach. Loose sand shifts under the weight of the body, making leg, seat, and back muscles work much harder to keep us upright.
Beach and riverbed sand is naturally low in dust and hardly gives off any residue when touched. This is because even though the sand is composed of crystalline silica it does not contain the dangerous dust.
Microorganisms are a significant component of beach sand – bacteria, fungi, parasites and viruses have all been isolated from beach sand, and some are potential pathogens.
Surf/Rip ResourcesA trip to the beach should be fun. Unfortunately, many people are injured or killed along our nation's beaches by hazards such as dangerous currents, tsunamis, heat and lightning. The National Weather Service can help ensure you leave the beach with good memories.
