A Warning of leaving plasic drinks bottles in your hot car

Posted by firstaidinstructor on May 11, 2009

We had this passed to us and have heard from many other sources about the probem of increased cancer risk from drinking from plastic containers left in hot cars.  Have a look and a think.

On the Ellen show, Sheryl Crow said this is what caused her breast cancer.

It has been identified as the most common cause of the high levels of dioxin in breast cancer tissue.

Sheryl Crow’s oncologist told her: women should not drink bottled water that has been left in a car.

The heat reacts with the chemicals in the plastic of the bottle which releases dioxin into the water.  Dioxin is a toxin increasingly found in breast cancer tissue.

So please be careful and do not drink bottled water that has been left in a car.

This information is the kind we need to know that just might save us!  Use a stainless steel canteen or a glass bottle instead of plastic!


This information is also being circulated at Walter Reed Army Medical Center

No plastic containers in microwave.

No water bottles in freezer

No plastic wrap in microwave.

A dioxin chemical causes cancer, especially breast cancer.

Dioxins are highly poisonous to the cells of our bodies. Don’t freeze your plastic bottles with water in them as this releases dioxins from the plastic.

Recently, Edward Fujimoto, Wellness Program Manager at Castle Hospital, was on a TV program to explain this health hazard.  He talked 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 especially applies to foods that contain fat.

He said that the combination of fat, high heat =2 0 and plastic releases dioxin into the food and ultimately into the cells of the body… Instead, he recommends using glass, such as  Corning Ware, Pyrex or ceramic containers for heating food.. You get the same results, only without the dioxin.

So such things as TV dinners, instant ramen and soups, etc., should be removed from the container and heated in something else.  Paper isn’t bad but you don’t know what is in the paper.

It’s just safer to use tempered glass, Corning Ware, etc.  He reminded us that a while ago some of the fast food restaurants moved away from the foam containers to paper. The dioxin problem is one of the reasons…  Also, he pointed out that plastic wrap, such as Saran wrap, is just as dangerous when placed over foods to be cooked in the microwave. As the food is nuked, the high Heat causes poisonous toxins to actually melt out of the plastic wrap and drip into the food.

Cover food with a paper towel instead.

    Claims that plastic bottled water containers stored in either warm environments (e.g., a hot automobile) or in frozen state “leach” unnamed chemicals that cause breast cancer or other maladies are not based in science and have no substantiated data. There are no studies which prove this theory. These allegations have been perpetuated by viral emails and media hype and only serve to frighten and confuse consumers.
    The vast majority of plastics used in food wraps, packaging containers and beverage bottles do not contain the chemical constituents that form dioxins, namely chlorine. In addition, dioxins are a family of compounds that are produced by combustion at extremely high temperatures. They can only be formed during combustion at temperatures typically above 700 degrees Fahrenheit; they cannot be formed at room temperature or in freezing temperatures.
    The U.S. Food and Drug Administration (FDA) comprehensively regulates the safety of foods and beverages, including bottled water. This includes a careful review of food and beverage packaging materials, including plastics, before allowing them on the market.
    With respect to leaving bottled water in a hot car, FDA has stated:
    • “It is true that exposing the bottle to higher temperatures may imply a greater degree of migration of substances from the plastic to the water [ed. note: or other beverages in similar containers]. However, in its safety review, the FDA takes into account exposures to higher temperatures, such as during storage and transportation of bottled water prior to sale, in its estimates of potential levels of migration of substances from the plastic to the water.”

    • “The levels of migration expected, including during periods of exposure to elevated temperatures in storage and transport (such as might be experienced in a closed vehicle in the sun) have, as discussed above, been determined by the agency to be well within the margin of safety. Therefore, the agency does not consider this situation to be a safety concern.”

    For approved plastics, FDA has found that the levels of migration to food of the substances due to the use of the plastics in contact with food are well within the margin of safety based on information available to the agency (i.e., toxicological testing has demonstrated that the cumulative dietary concentration of these migrants resulting from the use of the plastic materials in food packaging is at least 100 to 1000 fold lower than the level at which no toxic effect was observed in animal studies.) This means no short or long term health effects are likely to occur, even from life-long, daily dietary exposure to these substances migrating from plastic food-contact materials.

    On a purely scientific basis, Heat cannot create chloride or any form of chlorine from the molecular structure of PET, hence it also cannot create dioxin from burning or heating or freezing of PET plastic.

    The toxicological properties of polyethylene terephthalate (PET), a common plastic used for bottled water and beverage containers, and compounds that migrate under test conditions have been well studied. In its report on PET in food packaging applications, the International Life Sciences Institute (ILSI) summarized the large body of test data and demonstrated the safety of PET resins and compounds from food and beverage containers.
    The claim that plastic water bottles will release dioxins when frozen is entirely unfounded. In fact, it is scientifically impossible.
    In an interview conducted on July 14, 2005, Rolf Halden, Ph. D. of the Department of Environmental Health Sciences at the Johns Hopkins Bloomberg School of Public Health, set the record straight on dioxins in bottled water and refuted claims that dioxins were released when water was frozen in plastic bottles. “This is an urban legend,” he said. “There are no dioxins in plastics. In addition, freezing actually works against the release of chemicals. Chemicals do not diffuse as readily in cold temperatures, which would limit chemical release if there were dioxins in plastic, and we don’t think there are.”
    According to FDA, “ With regard to dioxins, we have seen no evidence that plastic containers or films contain dioxins and know of no reason why they would.”
    A wide variety of consumer packaging fabricated from plastic, not just bottled water containers. The International Bottled Water Association (IBWA) does urge consumers to handle and store bottled water containers with the same care and respect as they would any other food or beverage product.
