Many people feel that exposing cuts to sea water can assist in the healing process. According to this article in Medpagetoday, not only is this old remedy not correct, it is downright dangerous.
Most Vibrio infections in the U.S. are associated with eating raw or undercooked seafood, but of those studied, more than two-thirds of patients were infected while participating in recreational activities, such as boating, surfing, swimming, or walking on the beach, Dr. Dechet reported at a meeting of the Infectious Disease Society of America here.
Avoid being in sea water if you have open cuts. If you have an infection and have been in sea water lately, let your physician know asap.

Seawater, reason being avoid the Iron eating bacteria Vibrio Vulnificus, it’s an iron eating bacteria and this lady suffers from Bronze diabetes also called hemochromatosis, she being homozygous for C282Y mutation confirms that both her allele’s are carrying the mutation and it is autosomal dominant so there’s no way she has an acquired hemochromatosis from thalessemia or other anemia’s!
There’s a catch here though, she is much better off swimming in sea water because estrogen protects against vibrio vulnificus! 85% of the endotoxic shock that does occur with vibrio is in males because of lack of estrogen 😉
