We often get asked about Food Storage Shelf Life. We used to link out to a site that had all the answers, however it has somehow disappeared from the internet. Being that we still get asked the question, we thought it would be good to house the information ourselves for you. So for a great chart that gives Shelf Life for most of your Food Storage Items, click here (this information was found on shelfreliance.com).
Food Safety Throw Away Guidelines
As food ages it naturally will change in flavor, odor, and texture. The worse these conditions are the less likely we will be to eat a particular food, but if it were safe to begin with, and it passes the following food safety test now, then it should be safe. A good rule of thumb is “When in Doubt—Throw It Out.” (This list was taken from a handout produced by the Utah State Extension Service)
The following chart gives throw away guidelines.
1. Food was not processed properly. If improper processing times, methods, and/or recipes were used for home canned vegetables and meats, the jar may be sealed, but the product deadly—DO NOT TASTE—discard.
2. Look for the following signs of spoilage—DO NOT TASTE—discard:
- Bulging lid—lid must be definite concave, and seal cannot be lifted with fingers.
- Milky appearance to liquid—as food ages the liquid will become more cloudy and a residue will begin to form in bottom of jar—this is the food sluffing off, but the appearance should not be milky.
- Mold growth of any kind.
- Slimy appearance or texture.
- Rancid odor—especially in foods which contain any amount of fat, like dehydrated protein.
- Corrosion on inside of can, especially along seam (particular problem with canned foods older than 10 years or so.
- Rust—especially on seam or seal of can.
- Frozen can or bottle—freezing produces hairline fractures in seal and allows spoilage to begin.
- Off-smell—food generally changes in odor as it ages, if the smell has developed to the point it is undesirable.
- Food stored in non-food grade container—the container was not meant for food or once contained a non-food product (garbage bags, garbage cans, cleaning bottles or buckets, kitty liter containers, etc.).
