I used to work construction out on Siesta Key, Florida and numerous times I would cut myself somewhere or step on a nail. I found the salt water was the best thing for these wounds never having an infection and with rapid healing.
More Chicken Littles IMO. If it was a real health problem, there would be a lot more people coming down with these infections. Occasionally, we see someone in the news who has been infected, but, considering the vast numbers of people who go into the ocean each year, It's extremely rare. Do I go into the ocean right after a storm when the bacterial levels are high? Nope, but, others do, and some contract something because of it. you can't fix stupid.
The freedom of the internet means anyone - even the grossly uninformed can simply dismiss facts and spout nonsense like this. Vibrio vulnificus infections are common in this area and many other coastal areas. The lowest mortality rate estimate that I have found for Vibrio infections is 25%; note that it kills within 48 hours:

CDC and webmd etc have the same facts - for those interested in facts.
Chicken littles? Please post your medical diploma here. Everyone else - that post is an example of who to put on the ignore list.
