Hi All, I was searching on the net about which plastics are safe to drink from and re-use etc as I drink only out of plastic water bottles until now! Now I refill a high density polyethylene one with ozonated water. See link below that gives info on types of plastic you can re-use etc. From what I can see the PET (polyethylene) ones look bad to me - they are your average 500ml dirnking bottles so from now on I will just fill a glass up instead of buying plastic bottles - better for the environment too. It seems numbers in the triangles on the bottles - 2, 5 and 4 look generally safe to use. But have a look and make up your own minds. http://www.davidsuzuki.org/files/NC/newsletter/plasticsbynumber.pdf I will also ensure anyhting I microwave - which is rare for me anyway - not to microwave it in it's plastic container just in case. Thought this might interest some of you, the less chemicals for us the better! It's crazy that we have to do all this research because humans have gone too far modernized and now we don't know what we can eat or what we can't. I'm sure this is why there are so many unexplained illnesses.
