is it safe to drink water thats been frozen in a plastic container?
i have a coworker who i think is just being paranoid - she claims that freezing a water bottle in the freezer makes the water unsafe to drink. i've heard of the dangers in heating plastic, but nothing about freezing it... anyone have an answer?

I just watched a news special recently on nbc re: freezing water bottles.
I found this article that I copied and pasted. But I have also read on other websites that it does not.
"DIOXINS Carcinogens cause cancer. Especially breast cancer. Don't freeze your plastic water bottles with water as this also releases dioxins in the plastic. Dr. Edward Fujimoto from Castle Hospital was on a TV program explaining this health hazard. He is the manager of the Wellness Program at the hospital. He was talking about dioxins and how bad they are for us. He said that we should not be heating our food in the microwave using plastic containers. This applies to foods that contain fat. He said that the combination of fat, high heat and plastics releases dioxins into the food and ultimately into the cells of the body. Dioxins are carcinogens and highly toxic to the cells of our bodies.
Then I found this article from John Hopkins that says it does not
BALTIMORE -- Johns Hopkins researchers have responded to an e-mail warning against freezing water bottles. A recent e-mail hoax claims Hopkins scientists warned people that freezing plastic bottles releases dioxins into the water. But the researchers say that's entirely false -- they said freezing plastic water bottles will not expose people to dangerous chemicals.

According to Dr. Rolf Halden, of the Johns Hopkins Bloomberg School of Public Health, freezing actually works against the release of chemicals and scientists are not even sure plastics contain dioxins.
However, Halden does warn that another group of chemicals that are used to make plastic less brittle can be released if you place them in hot water or heat them in the microwave.
But Halden stresses that people should not be afraid of drinking water and that "you are more likely to suffer from the adverse effects of dehydration than from the miniscule amounts of chemical contaminants present in your water supply."
He also said people should be more concerned about the quality of the water they drink more than the bottle from which they drink it. Although people tend to assume bottled water is the safest route, Halden said city water is much more highly regulated and monitored for quality.

There is some growing evidence that plastic containers do leak carcinogens... both when they're frozen... or heated... as in a microwave. Just how significant the risk is, much remains to be seen, and most of the studies... so far have to do with heating... although as you said, I have seen some reports about freezing as well. But I can tell you I NEVER microwave my food in plastic containers... or with plastic wrap over it.

Yes it is safe. There is an urban legend about this. You can drink from plastic that has been frozen. When SOME plastics are heated they break down and actually put carcinogens into the food/drink.Source(s): Teacher

Dioxins aren't in most plastics, including water bottles. Furthermore if they did contain dioxins, they aren't released when frozen but rather when burned.

If the water was potable before freezing, it should remain safe after freezing. A few other notes...
Cold and freezing will not kill microbes and parasites
If you reuse water bottles, make sure you wash them thoroughly after each use

Yes, it is safe.
It is an urban legend that was addressed very specifically recently - there was even a segment on the Today show about it.

your co-worker is wrong it only bad to drink water out of a warm plastic bottle, because the plastic changes i think the chemical structure of water in the bottle but frozen water is fine to drink
