Not that I'm aware of.
The first story mentions it happened at Weedon Island just west of Tampa.
This area has been hit with pollutants from a shit processing plant in the past. The basins have overflowed due to heavy rains and the shit dumps into upper Tampa bay.
Could be related.
However,
I fish salt and some brackish water. Whenever I get stuck with a hook or a fish cuts me, I've always just washed up in the water the boat is sitting in. I've been doing it that way since I was a little kid.
Rebecca always wants me to put some chemical on it to clean the wound. I just do the "Arnold" thing and let it bleed.
There's bacteria everywhere and I've gotten my share of it on me.
Maybe I've developed an immunity to some strains.
