Using part of a can - how to store remaining?

I was once told that when I use only part of what's in a can, I should take the rest out and put it into some kind of regular dish before placing it back in the refrigerator. Apparently there was some idea that the opened can could impart something unhealthy back into the food.

Is this true? Should I really be moving the food to a different container?

There is a theory that the metal can leach into the food and contaminate it. I usually move it into a plastic container so that I can cover it.

This site - Food Safety Basics 2 - says to transfer to another container is kept more than one day. It's a pretty comprehensive list of how long various foods last.

I use little zip lock baggies for that too.

The food has been in that can for some time before you opened it. Any leaching would have already happened.

Whatever container you use should be airtigh to protect the contents.

I found out that food in glass containers less longer than if it was in the plastick container.

I think the point is that you can't safely store an unopened can. You need to store the leftovers in airtight containers, that's the reason to transfer it.

Once the can is open to the air the tin taste may transfer to the food more rapidly. The can may also rust. Some cans are now lined with a white vinyl-type coating which is supposed to help with this problem on the SHORT term. I always transfer to another container as I want a tighter seal with less air in the container.

I wish they made small cans of tomato paste. I only use maybe a tablespoon or so at a time. So I transfer it to a freezer box, and place it in the freezer for later use. Then the next time I need tomato paste I open another can only to realize later I had some in the freezer already!!
