BPA - new dangers discovered

As if we already didn't have enough to worry about, here comes new concerns about BPA (bisphenol A ).
The Green Guide has summed it up nicely

If you are like many readers of The Green Guide, you try and choose foods that are as free as possible of harmful chemicals such as pesticides. But if you consume canned soups, beans and soft drinks, organic or not, you also may be swallowing residues of a controversial chemical called bisphenol A (BPA) that can leak out of the can linings into your food. Nearly all can liners contain BPA, says Geoff Cullen, director of government relations at the Can Manufacturers Institute. BPA has also been found to migrate, under some conditions, from polycarbonate plastic water bottles. Depending on whom you talk to, BPA is either perfectly safe or a dangerous health risk.

Plastic water and baby bottles, food and beverage can linings and dental sealants are the most commonly encountered uses of this chemical. Unfortunately, it doesn't stay put. BPA has been found to leach from bottles into babies' milk or formula; it migrates from can liners into foods and soda and from epoxy resin-lined vats into wine; and it is found in the mouths of people who've recently had their teeth sealed. Ninety-five percent of Americans were found to have the chemical in their urine in a 2004 biomonitoring study by the Centers for Disease Control and Prevention (CDC).

Some scientists urge that action be taken now, regardless. "Science is not in the business of demonstrating anything beyond a shadow of a doubt," says Ana Soto, M.D., a professor and researcher at Tufts University School of Medicine in Boston, who has found that BPA alters mammary-gland development in mice. "We cannot wait that long to discover whether this chemical is harming human reproduction and development." However, because government agencies remain unconcerned, it is unlikely that BPA will disappear from consumer products anytime soon. A California bill to ban BPA in baby toys and feeding products was defeated in January. In the meantime ...

8 Ways to Avoid Harmful Chemicals in Plastics and Cans

1. If you already own polycarbonate bottles, including the Nalgene bottles popular on college campuses, labeled #7 on the bottom, wash them by hand with mild dishwashing soap, not in the dishwasher, to avoid degrading the plastic and increasing leaching of BPA (see "Picnic Perfect Plastics").

2. Even plastic does not last forever. Look for cracks or cloudiness on your reusable clear plastic bottles. See The Green Guide's survey, "A Nalgene Bottle Poll."

3. Use glass baby bottles or plastic bag inserts, which are made of polyethyelene, or switch to polypropylene bottles that are labeled #5 and come in colors or are milky rather than clear.

4. Choose soups, milk and soy milk packaged in cardboard "brick" cartons, by Tetra Pak and SIG Combibloc, which are made of safer layers of aluminum and polyethylene (#2) and also recyclable.

5. Choose canned foods from makers who don't use BPA, such as Eden Foods (www.edenfoods.com), which sells certified organic canned beans and other foods.

6. Eat fresh foods in season and save the canned foods for convenience or emergencies. The exception is some canned fruit such as that found in smaller fruit-cocktail cans, which do not require a liner, according to the Can Manufacturers Institute.

7. Buy or can your own fruits and vegetables in safe glass jars. For more, see Amy's Green Kitchen "In a Summer Pickle".

8. Some wines have been found to contain up to six times the BPA of canned foods. While most wines probably don't, it's another good reason to drink in moderation.

So there you have it. As always with a debate where there are many sides and truths, theres a choice to be made. Given this information, does an individual act on this information or ignore it.

I remember the time when I learned that not all plastics not microwave safe, and that one shouldn't microwave breast milk, as well as Teflon made pots and pans are now considered unsafe because of cancer fears. Treated Wood swing sets also a danger. Every day we learn something new. When plastic was first introduced it dramatically altered human history. It's virtually impossible to imagine a world without it.

I wouldn't be surprised to learn that potentially all men made things are somehow dangerous to all living things and some non-living as well I suppose. So unless there is a grand paradigm shift in society as a whole this is the reality we live in today.
