Can Canned Milk Go Bad?
Yes, canned milk can go bad, but it has a remarkably long shelf life. Proper storage significantly impacts how long it remains safe and palatable.
Unopened canned milk, when stored correctly, can last up to six months before a noticeable decline in quality. However, many sources suggest canned goods, including evaporated and condensed milk, often remain safe and usable for much longer—even a year or more past the "best by" date. This is contingent on the can remaining undamaged and stored properly.
Factors Affecting Shelf Life:
- Storage: Keeping canned milk in a cool, dry place such as a kitchen cabinet, basement, or temperature-regulated garage maximizes its shelf life.
- Can Condition: Dents, rust, or bulging cans indicate potential spoilage and should be discarded.
- Type of Milk: While the information refers to both evaporated and condensed milk, the specific shelf life may vary slightly depending on the type and brand.
Beyond the "Best By" Date
While manufacturers usually print a "best by" date on the cans, this doesn't necessarily mean the milk will spoil immediately after this date. The milk's quality might degrade, potentially affecting its taste and texture, but it's often safe to consume for a considerable time afterward. The general consensus from various online sources (Reddit forums and Quora answers) suggests that it's acceptable to use canned milk well past its printed expiration date, providing the can remains intact and there are no signs of spoilage (such as an unusual odor or change in appearance).
Identifying Spoiled Canned Milk
Always inspect the can before opening. Discard any cans that are damaged, dented, rusty, or bulging. Upon opening, check for:
- Off-odors: Spoiled milk will often have a sour or unpleasant smell.
- Changes in Texture: Curdling or separation may indicate spoilage.
- Unusual Appearance: Significant changes in color (discoloration) beyond a slight darkening can signal spoilage.
