Cripes. I went through this fear back on Monday. I'm still fine, by the way.
You live in a particularly cold climate. A vast
majority of these amoeba incidents have happened in hotter places.
I don't think there's been a single reported case in North America all year. These things pop up during the summer time. And even then, super rare.
Pretty sure the Louisiana incident was cause they had it growing in their personal water heater, the city tap water was not to blame for the incident.
So relax, I seriously think you're fine.
