1.0 out of 5 stars BPA Warning: Ball / Kerr lids are lined with it!, September 29, 2010
What a disappointment it was to learn that all Ball/Kerr metal canning jar lids are lined with the toxin BPA. I hope they're working on a lid that is 100% free of BPA, but in the mean time, if you're searching for lids without BPA, you might try Tattler lids. They are reusable and guaranteed to last a lifetime. There are others on the market as well.

Tattler lids leach out POM (formaldehyde) when heated (particularly heated with acids), so you're not much better off-- except that you do get to reuse the lids.

I found these lids and they look pretty good. Please let me know if you know if these leak POM too.

In reply to an earlier post on Mar 21, 2011 1:47:28 PM PDT
They do leak POM. For the record, though, BPA is eliminated by the body fairly quickly. With the short amount of time the food is touching the lids during the canning process, and the fact that the food isn't in contact with the lid at all during storage, I wouldn't worry about using the BPA lids. I don't know a ton about POM except that it does linger in the body awhile. I figure, the devil you know is better than the devil you don't know.

Just leave the proper amount of headspace one way or the other. Something else will kill you in this life long before POM or BPA will, and no matter what... your home canning is far better than the store-bought cans of food. I wouldn't sweat bullets over it :)

I researched this and learned that POM, the material Tattler lids are made from, does NOT release any formaldehyde unless it reaches 429F degrees. Home pressure canners do not go over 250F. POM does contain minute amounts of formaldehyde but there is no danger for use in home canning. Also, this type of plastic was approved in Europe which has stricter standards than the U.S.

Temperature may not be the only factor.. What about the acid in tomatoes and sauerkraut leaching? Its food to know they were approved in Europe (I dont trust USA conservative rule, allowing companies to lie to us to sell us stuff)..

I am canning my sauerkraut at room temperature for the probiotics.. The acid and salt do the preserving (much better when stored in the frig)..

AND: are we talking about these:

Reusable Regular Canning Lids & Rubber Rings, from kitchen krafts (in case amazon strips out the link)..

It's not worth exposing young female children to even small amounts since BPA has been linked to various cancers due to exposure when young. Honestly, stuff shouldn't be legal in any amount at this point considering what we now know.

In reply to an earlier post on Aug 25, 2011 5:05:41 PM PDT
I know, a lot of things shouldn't be legal. BPA in canning lids, mercury in fluorescent bulbs, propylene glycol in vaccines, aluminum in antiperspirants, hormones in meat, property tax... *sigh*

What's a mom to do? :(

"What's a mom to do.".

People need to stop voting for conservatives (these things are outlawed in other countries).. In the conservative world view in America it's all about cold cynical profit and not even 1- percent of thought goes into the well being, health, liberty, the pursuit of happiness.. Actually, if you watch closely, they they work very hard to conceal the harm their products cause (they do indeed put a price on human lives, and work hard to lower that price / tort reform. IE: meaning they can't be sued in any meaningful way).. I hope you all like my answer.. But I know politics is like a religion to some people, and no amount of facts will make you "THINK" about exactly what you are supporting.. If you look at today's Republicans, they pretend to be the religious party, then do the exact opposite of every thing Jesus says (in the KJV, which is "their" version).. Today's republicans are also very disturbingly following in the footsteps of the early Nazi's in Germany (google it).

Make a jar with a glass lid shaped like a 1/2 inch tall cup.. So it fits over the outside of the jar.. Then the jar needs a lip to meet the lid.. Hopefully, with all the technology available, you would think they could make one of those wire things that clamps down the lids THAT ACTUALLY WORKS.. Now we could probably use BPA plastic, because the food doesn't touch the outside of the jar.. But I would still like to see some kind of natural material like simple wood or cork..

Oh, I'll probably get downvoted for this too...

Bobbler made a perfectly valid reply as to one method that could be used to make these lids illegal, in response to previous comments! Indeed, if you do not want BPA in the lid of this jar, a solution would be to vote for those who would regulate such things. (And he even thought outside the jar and gave us a bonus answer!)

(The Nazi comparison might be a bit much for an Amazon product review, though.)
