How Hot Can Canned Goods Get?

[KAYLINDA]

Something I never thought about before....but how warm do you think a room can get before the temperature will affect canned goods?
Thanks in advance!

The question more is how hot can a
"room" GET?? What "room" are your canned goods in? Do you reside inside a furnace? A nuclear reactor? My kitchen gets very hot in summertime, but certainly not hot enough to affect my canned goods. Remember the reason for canned foods to begin with: Preservation in all forms of bad conditions. A canned food would have to be boiled, lid on (eeek...let's not talk explosions of metal, shall we?? ) before any danger ensued. What exactly is your concern? Be more specific.

We are building on a storage room that will be insulated...but no air conditioning. In the summer our outside temps can reach 110...
We feel our room will be 20 degrees cooler...or 90. Just wondered if keeping any kind of food at 90 degrees for too long would hurt it....and how long is too long?

The general rule of thumb is that canned food has a shelf life of at least two years from the date of purchase. It is recommended that all canned food be stored in moderate temperatures (75° F and below).

I am sure there are other references on the internet as well. Use "canned food shelf life" and "canned food safety" as key words for searches.
