How to Decode Expiration Dates on Dairy Products: A Guide to Safe Consumption

When it comes to dairy products, freshness is paramount. Understanding how to read and interpret expiration dates is crucial for ensuring safe consumption and avoiding potential health hazards.

Expiration Date Basics

Expiration dates indicate the manufacturer’s estimate of when the product will reach its peak quality. It’s important to note that these dates are not absolute deadlines but rather guidelines to help you make informed decisions about food safety.

Decoding Expiration Dates

Check for two types of expiration dates on dairy products:

Use-by date: This indicates the last day the product should be consumed for optimal freshness and flavor. Consuming after this date may compromise taste and texture.
Sell-by date: This is a recommendation for retailers to sell the product before this date. It doesn’t necessarily mean the product is unsafe to consume after this date, but its quality may start to decline.
