Question
In our new (used) home, we have found on a basement shelf, 15 jars of canned tomatoes.  I can't budge the flat lids off, the seal is so tight. The color looks good. Could I use these canned tomatoes to make hot dishes/soups? Or,do I toss them down the disposal?   I hate to waste food, but don't need to take chances, either.  

Answer
Hi Martine,

Wow -- 14 year old home canned tomatoes!!!

Our general rule of thumb is that home canned foods that are sealed, show no signs of deterieration (color changes, foaming, leakage, etc)are safe to eat -- but the quality of the product may have changed to where it is not desirable.  That is why even commercial canners of tomatoes date their products and recommend using within 2 years. Unlike women, canned foods do not get better with age!!!

However, since you do not know what proceedures were used to can the tomatoes (canning guidelines for tomatoes changed in the early 1990's)my recommendation would be to discard the tomatoes.

While they may be safe, my recommendation is to pitch the tomatoes. Better safe than sorry.

If you have additional questions, please let me knnow.
