bisphenol-A.. thoughts

April 12th, 2007, 11:55 AM
i received an email that stated pop top cans contained the ingredient above, and that it was very dangerous to cats, especially female cats as the ingredient showed to cause hyperthyroidism and tumours in this area. Did a bit more research, some non pop top cans can be suspect as well. Apparently this ingredient is in a ton of things! Anyway since the recall, food lists get slimmer, and most of the good ones seem to use cans, not plastic tins or pouchs, for wet food that is. Just wanted to know what your thoughts were on this.:frustrated:

Do you know for sure the email was from a reliable source?

My friend who is studying to be a vet actually is doing a report on hyperthyroidism in cats and found out that cats who ate canned food were more at risk, though she didn't know exactly why. Maybe this is the reason.

It is interesting, and I hope someone knows more about this.

i did a search after that.. found links on tanyas renal site for cats, and many others.. got me concerned.

Do companies have to list it on the ingredient list? I looked up some ingredient lists for pop top cans and didn't see it. I'll check out the renal website you mentioned.

this ingredient has to do with the can itself, not the food.. is that what you meant? there are a few studies that were done a few years ago, you can find them just by searching the ingredient itself or danger in pop top cans. Seems to be a big debate but the evidence was there through studies. It hasnt stopped companies from producing cans, apparently pouches and plastic top liners are safe, i just dont know any of the good food companies that are talked about in these forums that package their foods that way.

I wonder why only those cans would have it and not the regular cans...

Aha, I get it. That's just creepy - the more I find out about the way pet food's made, the less I like it. :mad:

i agree beagle girl, and prin i have read that they are stating all aluminum cans now in some cases too, so thus the confusion. Apparently this ingredient was in some baby bottles and proved toxic and a lot of folks freaked. For canned food, has something to do with the plastic coating or lining in the pop top cans. One more negative thing about pet foods i didnt need to know..:frustrated:

Some cat food cans pop tops have a white underneath when you open them instead of just metal. Would that be where this ingredient is? I have noticed that difference in cans when I wash them out. The ones you have to open with a can opener always have a much thicker metal top.

I would imagine it would be in the white plastic coating.

The following information is from the Cancersmart Consumer Guide I have from the Labour Environmental Alliance Society in Vancouver.

Bisphenol-A is a chemical found in polycarbonate plastic. It is an endocrine-disrupting chemical and also mimics the female hormone estrogen and has been shown to cause defective cell division. Research has shown that it can leach out of the plastic into liquid especially as the plastic begins to wear.

After learning that I have now bought those SIGG metal bottles for our drinking water and don't use the Nalgene polycarbonate ones anymore.

The safest plastic to use is HDPE (high density polyethylene identified by the # 2 recycling triangle on the bottom), LDPE (low density polyethylene, #4) and PP (polypropylene, # 5).

Maybe if you contacted the companies they would beable to tell you what type of plastic they are using to line their cans?

That plastic coating is in a lot of canned foods for people too. I think this is going to be like the teflon coating controversy.
