Certainly! Here’s a detailed and unique article explaining the common misunderstanding about “Best By” or “Best Before” dates on food cans and how to interpret them properly, step by step.

Most People Get This Wrong and Toss Out the Can: The Right Way to Read “Best By” or “Best Before” Dates

Every time you open your pantry, you might find canned goods with dates stamped on them—often labeled as “Best By,” “Best Before,” or “Use By.” Many people see these dates and instantly assume that the food is no longer safe to eat after that date passes. As a result, perfectly good food gets tossed into the trash, contributing to unnecessary food waste and expense.

But what if I told you those dates don’t necessarily mean the food is spoiled or unsafe? Understanding what these labels really mean can save you money, reduce waste, and help you make better decisions about the food you consume. Here’s a step-by-step guide to decoding these dates and how to determine if canned food is still good.

Step 1: Know the Difference Between “Best By,” “Best Before,” and “Use By”

• Best By / Best Before: These dates indicate the period during which the manufacturer guarantees the best flavor, texture, and quality of the product. They are about quality, not safety. After this date, the product might lose some of its freshness or taste but is often still safe to consume.
• Use By: This date is more strict and usually applies to highly perishable items. It signals the last date recommended for use while at peak quality and safety. Consuming after this date may carry some risk, especially for vulnerable groups.

Canned goods typically carry “Best By” or “Best Before” dates, not “Use By” dates, meaning they remain safe to eat beyond those dates if stored properly.

Step 2: Understand How Canned Food is Made and Preserved

Canned foods undergo a sterilization process where they are sealed in airtight containers and heated to kill bacteria and enzymes. This process preserves the food for long periods—often years—if stored in cool, dry places.

Because of this:

• The can acts as a barrier to contamination.
• The sterilization process keeps food safe long after the “Best By” date.
• Quality might degrade over time, but safety is typically not compromised unless the can is damaged.

Step 3: Check the Physical Condition of the Can

Before deciding to toss or keep a canned item past its date, examine the can carefully:

• No rust: Rust can weaken the can and cause contamination.
• No dents: Especially on seams—dents may compromise the seal.
• No swelling or bulging: This indicates bacterial growth and gas production inside, meaning the can is unsafe.
• No leaks: Any liquid leaking means spoilage or contamination.

If the can is physically damaged, discard it regardless of the date.
