Not to be an alarmist, but the more research I do on the topic of human exposure to bisphenol-A (BPA), the more concerned I have become. The list of potential exposures is long, but we certainly have a choice to limit these. And as consumers, we must make our preferences known to lawmakers and manufacturers. Unfortunately, the FDA opted not ban the use of BPA in food packaging on 3/30/12, but stated that they will continue to evaluate the risks of BPA to human health.
Here’s a list of the most common (known) sources of BPA:
CANNED FOOD –most canned food has lining containing BPA; more manufacturers are starting to use BPA free cans (see Mark’s Daily Apple for specific brands); canned food is considered a significant source of BPA
THERMAL PAPER RECEIPTS—eg. ATM, gas station, store receipts; large amount of BPA–in the order of 60-100mg, as opposed to nanogram amounts leached from polycarbonate bottles!
POLYCARBONATE BOTTLES (labeled #7 or #3)–including water coolers at work, older Nalgene water bottles (newer Nalgene and Camelbak bottles are BPA free)
SODA AND BEER CANS –BPA is particularly soluble in alcohol, so opt for bottled beer
METAL WATER BOTTLES–such as Sigg (prior to their admission of BPA lining and exchange program in 2008/9); Kleen Kanteen has no BPA and Sigg’s newer containers are BPA free
TUPPERWARE (if labeled #7)
PLASTIC WRAP –no pthalates since 2006; now made with LDPE, which has fewer contamination concerns; best not to microwave.
BABY BOTTLES and PACIFIERS –look for BPA- free bottles and pacifiers; some states have outlawed the use of BPA in baby bottles (as have other countries including Canada, EU, United Arab Emirates, China, Malaysia)
DENTAL SEALANTS and FILLINGS (see post BPA and sealants)
MOUTHGUARDS (check w/ manufacturer)
PIZZA BOXES –many are made from recycled newspaper and receipts, which both contain BPA
