It's not surprising being that SO MANY people take antibiotics and some waste is getting to the oceans. I don't remember where I read about the testing of drinking water around the country in different cities, but here in SF, they found high levels of sex hormones in the drinking water. In other cities, they have found high levels of residue from cardiac medications and diuretics.
It's yet another sign that we are over prescribing medications and TOO many people in this country are medicated. In my opinion, it's scary and is something that really needs to be looked at and prevented. What about the effects on the marine life, I wonder if this bacteria affects them in the same way or even similar?
