Does freezing a water bottle really cause cancer?!
Question:
Does freezing a water bottle really cause cancer?
Answers:
The Internet has been flooded with email warnings to avoid freezing water in plastic bottles so as not to get exposed to chemicals that can cause cancer (carcinogenic dioxins). One hoax email was even erroneously attributed to Johns Hopkins University where Professor Rolf Halden is an expert on dioxin contamination in the environment. He sets the record straight on dioxins in the food supply and the risks associated with drinking water from plastic bottles and cooking with plastics.
