Canned Food Safety: Understanding “Best By” Dates
Navigating the world of food expiration dates can be confusing. Many people assume the **“Best By”** labels on canned goods mark a hard deadline for food safety, but the truth is more nuanced. These labels are primarily **quality indicators, not strict expiration warnings.**
Understanding “Best By” Dates
A **“Best By” date** isn’t the same as an expiration date. Instead, it reflects the manufacturer’s estimate of how long the food will retain its **peak freshness, flavor, and texture.**
For canned foods that are properly stored, this often means they are still perfectly **safe to consume long after the “Best By” date has passed**—though you may notice subtle changes in taste or texture over time.
The Long Shelf Life of Common Canned Foods
Canned goods are thermally processed to kill bacteria, giving them a remarkable longevity. Here’s how long some pantry staples can last beyond the printed date:
A Checklist for Safe Consumption
Even with their long shelf life, it’s important to carefully inspect canned foods before eating. Here’s what to look for:
- Check the can exterior: Discard any cans that are **dented, rusted, bulging, or leaking.** These defects can compromise safety.
- Smell and inspect after opening: If the food has an unusual odor, color, or texture, it’s safest to throw it away.
- When in doubt, toss it out: It’s better to lose one can than risk foodborne illness.
Essential Storage Tips
Proper storage is key to extending the life of canned foods:
- Store in a **cool, dark, dry place** away from direct sunlight and extreme temperatures.
- Keep cans **upright** to help maintain seal integrity.
- Use a **first in, first out** rotation system—place newer cans in the back and older ones up front.
- Handle cans gently to avoid dents or damage.
- Once opened, **transfer any leftovers into a clean, airtight container** and refrigerate immediately. Never store food in the open can.
