Catching E. coli is no fun under normal circumstances; now imagine you were literally swimming in the stuff. That’s the reality around various rivers in Johannesburg, South Africa, where the amount of E. coli bacteria in the water is way beyond acceptable levels. Some areas, like the nearby Cheetah Bridge, host 240 times more E. coli than what is considered healthy. The more fit-and-trim areas, such as Kaalspruit, only exceed the healthy limit by 190 times.The problem doesn’t appear to be going away, as the local government is in full denial about it. However, when health officials make it clear that drinking a particular bit of water could very well kill you, it’s probably not the worst idea to listen to them
