...no, but there are often half tins of stuff in our staffroom fridge...the only thing for me would be a tin of beans and I microwave them anyway so I couldn't do that in the can anyway and would put them in the container that I was going to microwave them in....

..I don't really use much tinned stuff...

You should never put open tins in the fridge. The metal can transfer/react to the food. :nono:

Q. "When I was a kid, I was told that it was dangerous to leave an open can of food in the fridge for too long. Is this true?"

A. There's a persistent rumor that storing food in open cans puts you at risk of botulism - but this is a myth. C. botulinum is an anaerobic bacterium, meaning that it prefers an oxygen-free environment. Improper canning could allow the bacteria to multiply inside sealed cans but commercial food packers have stringent systems in place to prevent contamination. Assuming that the food was properly canned to begin with, storing an open can in the fridge doesn't put you at increased risk of food poisoning.

Nevertheless, storing food in open cans can give the food a metallic flavor, especially acidic foods like tomato sauce or pineapple chunks. Oxygen may also oxidize the exposed metal of an open can. Finally, it's hard to seal an open can so food may dry out and/or transfer flavors to other foods in the fridge.

No matter what kind of a container its in, however, food in the fridge has a limited shelf life - so try to keep track of what's in there and have a plan for using up leftover ingredients within a few days.

Why open a tin if you dont use it all?

Never put open cans in the fridge, as the metal may transfer to the can's contents – place the contents in a storage container or covered bowl instead.

Just to add to that. It's not bad for health but can ruin the flavour of food.

how would that work but not work when the can is sealed?. Cans do not have a lead mix any more and the insides are coated.

The metal can still react and ruin the food :laugh:

I live on my own. I never use a full can of anything. Mind you, I only keep stuff a day or so once it's open.

The only thing that I wouldn't use all off in one go is sweet corn, if I'm adding it to a dish a whole can is too much

Yes Ben I am looking for a little science and evidence :pipe:

I always put the contents into a plastic or china bowl and cover with clingfilm..

I put it in a dish and cover it with foil because open tins in the fridge can be harmful

Evidence please
