Bisphenol A in Canned Foods

Just received this warning this morning from the Organic Consumers Association...


An alarming new study from the Environmental Working Group analyzed samples of canned fruit, vegetables, soda, and baby formula on sale in the nation's supermarkets and found that more than 50% were tainted with a chemical linked to birth defects, ADHD and cancer. The chemical, bisphenol A (BPA), is an ingredient in plastics that lines food cans. According to the study, the chemical has been leaching into foods at levels up to 200 times the government's recommended "safe" level of exposure. According to Dr. Frederick vom Saal, a professor of biology at the University of Missouri-Columbia, and a long-time expert researcher of BPA, there are 94 scientific studies indicating deleterious health effects from BPA. "If BPA was treated as a drug, it would have been pulled immediately. This chemical can be replaced right now by safer materials, and the public would never notice the difference." OCA is planning to launch a campaign later this year to pressure food companies, especially organic companies, to stop using BPA-tainted cans and other toxic or non-sustainable packaging.
Learn more:


* Metal canned beverages appear to contain less BPA residues, while metal canned pasta and soups contain the highest levels.

* Canned foods in glass containers are not a BPA risk.

* Plastics with the recycling labels #1, #2 and #4 on the bottom are safer choices and do not contain BPA.

* One-third of liquid baby formulas have high levels of BPA. Powdered formula packaging is generally considered safer.

* Avoid heating foods in plastic containers and do not wash plastic containers in a dishwasher.

* When possible, opt for glass, porcelain and stainless steel containers, particularly for hot food or liquids.

* Do not let plastic wrap touch your food in the microwave, or better yet, avoid microwave ovens altogether.

* Many metal water bottles, such as those sold by the brand Sigg [see correction about Sigg under COMMENTS -D] are lined with a plastic coating that contains BPA. Look for stainless steel bottles, such as those sold by Real Wear [couldn't find this company on the web - D] and Kleen Kanteen that do not have a plastic liner.

Debra, and the Greenguide claim there's no BPA in Sigg water bottles. Can I ask your source of information?

I just received this email from

We just wanted to send your our response to the recent alarm over the SIGG water bottles:

Thank you for your inquiry – we certainly appreciate your concern. Based on the recent volume of inquires we've been getting about the SIGG bottle lining, we are confident that there is a good amount of rumors flying around. Below is a statement directly from SIGG regarding the SIGG bottle lining:

“The proprietary SIGG bottle lining is a water-based, non-toxic coating that is baked into the interior walls and remains flexible and crack resistant for the life of the bottle. This special SIGG lining is not plastic – it is a micro-thin epoxy… SIGG bottles exceed FDA requirements… Unlike common Lexan plastic water bottles (polycarbonate #7), which studies have shown over time may leach harmful chemicals like bisphenol – A (BPA), SIGGs have been thoroughly tested to ensure they are 100% leach-free and 100% safe!” (SIGG 2007 Product Catalog)

Although we are sure that SIGG bottles are safe, we’ve contacted SIGG for a response to the misinformation floating around on the web. As soon as we receive a response from them, we will be sure to make this information public on our website."


I am writing to you in regards to a posting you have on your Green Living Q&A blog with the heading “Bisphenol A in Canned Food” . In it you offer the consumer tip from the EWG’s consumer tips stating that :

* Many metal water bottles, such as those sold by the brand Sigg are lined with a plastic coating that contains BPA. Look for stainless steel bottles, such as those sold by Real Wear [couldn't find this company on the web - D] and Kleen Kanteen that do not have a plastic liner.

I can assure you that SIGG bottles are NOT made with a plastic liner and are in fact lined with a proprietary non-toxic, water-based resin which is extremely stable and has been refined over decades of study. The BPA issues surrounding Lexan plastic bottles (polycarbonate #7) involve the migration of chemicals from the plastic into the contents of the bottles. On the other hand, SIGG bottles have been thoroughly tested in Europe to ensure 0.0% leaching of any substance - no trace of BPA, BPB or any phthalates.

Based on the confidence we have in our product backed by numerous laboratory studies, we have questioned the EWG and requested that they provide us with the testing they have conducted on SIGG – or alternatively to remove the “SIGG” mention from their website if they have not tested SIGG. Within 24 hours of this request, the EWG removed SIGG’s name from their report. Here is the link:

We understand the controversy and concern surrounding BPA leaching from some plastic water bottles and can assure you that SIGG bottles are leach-free and 100% safe. We are upset about the misinformation which has circulated and are working feverishly to clear the good name of SIGG.

Thank you,

Going off on another tangent....Number 5 plastic doesn't leach BPA does it? It wasn't listed as safe in the first posting, but I was pretty sure it was safe, if not the safest of plastics.

COMMENT FROM DEBRA: The only plastic I know of that leaches BPA is polycarbonate.

Pretty tricky wording by the folks at Sigg. She sure can dance the Two Step. They never say that that bottles don't contain BPA. They say they don't leach BPA. That is two different things. The LOC they are using is 2 ppb. If the Sigg leaches below that rate then they didn't or couldn't test for it. The BPA studies have shown that levels below 2 ppb are still a problem.

If Sigg is using an epoxy liner than there is a very very good chance that BPA is used in the production.

We drink a lot of coconut milk as a dairy substitute, and cannot find any in glass bottles, or a canned alternative. Does anyone have any suggestions or found any other sources?

Here's an article that shocked me, about BPA in Sigg bottles:

It's the first time I heard of that and then I googled the subject and found this post. They replaced the copper-colored liner with a BPA-free version in 2008, so when this article was posted, BPA was indeed present in the Sigg liners.

And the Sigg exchange program:
