There is a controversy over whether all plastic food containers are safe for consumer use. Many consumers want to find BPA free bottled water brands, as well as products for use by small children. Others are reassured by claims that chemical leaching is not a significant problem in modern food, beverages, and plastic goods.
The proper chemical name is bisphenol A, a component of polycarbonate plastics and epoxy resins. Polycarbonates are commonly used in food packaging. Epoxy resins are used to line metal cans and bottle tops. The lining prevents the metal from reacting with foods or liquids. However, many health researchers caution against using polycarbonates in products like baby bottles, and studies show that chemical taints may leach into canned foods from the protective resin lining.
Although the fact that this chemical can leach into food and liquids is known, the FDA (the regulatory agency for the US food and pharmaceutical industry) does not feel that the levels of contamination are high enough to pose a threat to human health. However, other health experts feel that unborn and very young children can be harmed by any level of BPA.
The FDA, with its investigation on-going, recommends that people use plastic containers properly, keeping them from high heat (as in the dishwasher or the microwave). It also suggests limiting the use of foods in metal cans. Choosing highly acidic foods like tomato sauces in glass rather than metal containers is one way to lower exposure. The fact that Europe has banned BPA for many uses has fueled the controversy.
Bisphenol A is an estrogen mimic which can be retained in the human body, where it may increase cancer risks. Researchers have found links to brain and prostate gland development problems in unborn children and infants. For this reason, many people want to avoid this chemical altogether.
Concerned consumers should look for pacifiers, infant formula bottles, 'sippy cups', and teething rings labeled 'BPA-free'. They may also want to avoid this chemical for their own use by carefully selecting foods and beverages packaged in plastic. Polycarbonate containers will have a '7' recycle code on the bottom.
It's relatively easy to find drinking bottles that are free of this chemical. These include glass or glass-lined bottles, metal ones, or plastic ones that aren't polycarbonates. However, getting information on particular brands of bottled water that comes in BPA-free bottles is more difficult. It does help to check the number on the bottom of the bottle. A number 2, 4, or 5 means that the container is made from a safer form of plastic.
If you want to make sure about a commercial brand, call the manufacturer directly and ask a customer service representative. The representative will be glad to tell you if the manufacturer's bottles are in fact BPA-free. Otherwise you can minimize exposure by using glass, stainless steel, or porcelain food and beverage containers.
