I purchased a Steripen handheld UV water purifier. It uses UV light to treat water that may be contaminated. The claim is that the UV radiation damages the microorganism in a way that prevents reproduction, and that microbes that can't reproduce can't make you sick. But from my memory of Microbiology class many years ago, I recall that some bacteria release endotoxins that cause illness. So I'm thinking that even if I used this device on a glass of lake water that had a significant amount of bacteria, they still might dump endotoxins into my system if the cells are lysed in my stomach acid. Any thoughts on this? Thanks!
