Hello all. My mom told me once never to put cans in the fridge because you can get food poisoning. Is this true? Some cans say store at room temp but will letting them get cold harm you?

Once you open the cans you should store the unused portion in another container. Not the can.

Unopened cans/ no problem in the fridge.

Is it a safety issue or a taste issue? My mom always put leftover canned stuff in a separate container too, but I never asked why. They sell can covers for pet food... and I use them... could I be making my doggie sick? [Eek!] I don't leave unfinished portions of MY food in the can, but for some reason I didn't extend the practice to my pup's dinner...

You can find more on this here

The impression I get is that if the food is covered (because it goes on to say that cans with resealable lids are okay), then it won't spoil as quickly.

I also found several links about covering dog food, so don't worry about poisoning your pets.

However, I too always remove the leftovers from the can and put it in a plastic (tupperware like) containers.

Thanks for the link, 5 continents! The can covers I use are pretty much like the resealable lids, so I guess Zelda's food stays safe and yummy in the fridge.

This is because when a can has been opened and the food is open to the air, the tin may transfer more quickly to the can’s contents.
Then, in the "kitchen foil" section:

This is because aluminium can affect the taste of these sorts of food, especially if they are stored in aluminium containers for a long time.
So it sounds to me like you're not supposed to do it because your food will taste metallic, rather than you'll be poisoned.

It used to be a safety issue.(It may not be so much now but Mum taught me to do it that way so I do.) There's a rational reason
Older alum cans may not have been treated on the inside surface as well.

Exposure to the air may cause some oxidation of the inside of the can.
Citric juices can speed this process if left in an opened can.

My mom told me never leave food in opened aluminum cans because you'll get alzheimers. I don't think she has anything to back that up though.

Hmmm... around the Holiday season, we always seem to have a can of cranberry sauce in the 'fridge and I never notice any difference.

Yeah this is basically what my mom says...oxidation and whatnot...but I'm guessing that's not a problem anymore?

I can verify from experience that tomato sauce and chili both start tasting metallic if the food is left in the opened cans. I think it all depends on the type of can. For example, I buy nacho cheese from Sam's Club in number 10 cans. I can keep the cheese in these cans in the fridge for a couple of weeks without noticing any metallic taste. These cans seem to have some sort of enamel coating on the inside.

Then again, it might just be that the cheese is less acidic than the tomato sauce and chili.

In the restaurant biz, the health inspectors said the same thing. They knew that treated linings weren't an issue, but the laws don't always reflect reality.

Further, when you open a can you have a ridge at the top from the can opener. If not sealed air tight, food remainants will spoil on that portion quickly, while the rest of the food in the can remains OK longer. When you pour past the spoiled portion, you'vr contaminaited everything else.

I think ~my~ mom told me that just because she didn't want us kids spilling stuff all over in the fridge. [Big Grin]
