We've just had an email at work -
Please can I remind you that opened cans of food should not be kept in the fridges, any food that needs to be stored from opened cans must be put into a sealed plastic container. The food standards agency advise that opened tin food can oxidize and should therefore be transferred to sealable containers for fridge storage. Please see extract from their web site below:
When you have opened a can of food and you're not using all the food straight away, empty the food into a bowl, or other container, and put it in the fridge.
Don't store food in an opened tin can, or re-use empty cans to cook or store food. 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.
This advice doesn't apply to foods sold in cans with resealable lids, such as golden syrup and cocoa.
Not doubting them (much!) but how much truth is there in this? And if so how harmful is it, if at all?
We do it sometimes. I'm still alive......
