A lot of pet food cans are lined with material that includes BPA, bisphenol A. This substance is linked to cardiovascular disease and diabetes. Dr Jane Bicks, product formulator for Life's Abundance says this about the cans they use - "Way ahead of you on the cans by about 20 years. I was one of the first investigators with hyperthyroidism in cats. I did a retrospective study to determine the possible causes of it. Canned cat food was one of the possible causes.Thus when I made canned food I selected the company that does not have BADGE lining. Most canned companies have that horrible lining."BADGE, by the way, is another name for BPA.
Here is a direct statement from Life's Abundance:
“We do not use BADGE coatings in any of our canned foods.” In addition, Life's abundance stated the following in their response…”BADGE (BPA) COATINGS ARE USED IN 90% OF ALL CANS. This type of lining is considered an epoxy resin which have achieved wide acceptance in protective coatings, including coatings for food and beverage cans, because of their exceptional combination of properties such as toughness, adhesion, and chemical resistance. The most widely used epoxy resins are based on bisphenol A diglycidyl ether (BADGE). BADGE is a major component in all bisphenol A / epichlorohydrin based liquid epoxy resins. It’s entire
chemical nomenclature is Bisphenol-A Diglycidyl ether or 2,2-bis(4-hydroxyphenyl) propane bis(2,3-epoxy-propyl) ether.
OUR CAN LINING CONTAINS BFDGE. This is used in the aluminum 3oz and 5.5 oz cans. Even though some of the letters seem the same, the compound we use, is an entirely different compound from BADGE. BFDGE stands for Bisphenol-FDiGlycidyl ether or bis(hydroxyphenyl)methane bis(2,3-epoxypropyl)ethers.
The purpose of lining is exactly the same as why you might coat a surface with lacquer-protection. The purpose with food contact surfaces is to protect the can from the food (to prevent rust, etc) and the food from the can. There are many properties such as adhesion to the metal and ability to withstand processing and migration of food chemicals (especially acid) which need to be considered in selection of compounds. Additionally, properties to prevent sticking of the food to the lacquer on the lid need to be considered. Cans are coated on both sides but the needs are obviously different.”
My note:**Be a safe consumer,if you are feeding a canned food other than Life's Abundance call the company and ask about the can lining. 90% of the canned foods contain badge (BPA) lining.As of right now I don't know any "large" cans that are non-badge...only the small cans.
