I wanted to put this in the general so more people would see it.
As some of you know I have been researching CRF since Duffy was just diagnosed & came across this info re canned food with pull tab tops:
From http://www.felinecrf.org/nutritional_requirements.htm#food_composition
Unfortunately, a recent study, Epidemiologic study of relationships between consumption of commercial canned food and risk of hyperthyroidism in cats (2004) Edinboro CH, Scott-Moncrieff JC, Janovitz E, Thacker HL & Glickman LT Journal of the American Veterinary Medical Association 224 (6) pp 879-886, indicates that cats who eat tinned food, particularly from pull-ring tins, appear to be at increased risk of developing hyperthyroidism. It is thought that this may be related to the lining used in these tins, bisphenol-A (BPA), a potential endocrine disrupter. It is therefore probably worth trying to feed your cat food from foil pouches or plastic trays rather than from tins. If you do use tins, be sure to store any leftover food in glass containers in the fridge rather than in the tins themselves. The Food Standards Agency has more information on this.

Some cans are fully lacquered on the inside to control and reduce tin levels, and allow them to contain acidic foods.
Bisphenol-A is one of a large number of substances that may have the potential to interact with our hormone systems.
These substances are referred to as "endocrine disrupters". Research is still going on to establish whether or not bisphenol-A could have this effect in people. Particular concern has focused on the sex hormones, the female oestrogens and male androgens, because of their important roles in the development of the reproductive system.
Although there is evidence that some wildlife species have been affected by exposure to endocrine disrupters, there is still no conclusive evidence of a link between harmful effects on human reproductive health and exposure to these chemicals.
What you can do
You should not re-use empty cans or tins to cook or store food because this can increase the likelihood of the substances used to make the cans getting into the food.
Once a can is opened and the inside of the can comes into contact with oxygen in the air, corrosion, which is minimal while a can is sealed, becomes more rapid.
Half opened cans of any type of food should not be left in the fridge. It's best to place leftover food in a sealable container that can be stored in the fridge or freezer. This advice does not apply to those foods sold in cans with a re-sealable lid, such as golden syrup or cocoa.
To make sure your canned food is at its best:
- store cans in a cool dry place
- use your oldest cans first
- if a can is bulging or rusting, throw it away
I think this is good information not only for pet food from tins but also people food. It mentions the food is safe inside the sealed cans, just once opened the contents should be stored in glass containers in the fridge. :)
