❓ Frequently Asked Questions About Shelf Life
Find answers to common questions about shelf life and expiry.
What’s the difference between sell-by and use-by?

Sell-by is when retailers should stop selling a product. Use-by is when consumers should consume it for best quality/safety. Use-by is typically later and more important for expiry.
Can products last past expiry?
►
Many products can last past expiry if stored properly. However, safety and quality degrade over time. For medications and fresh foods, follow expiry dates strictly.
How does temperature affect shelf life?
►
Temperature significantly impacts shelf life. Cool, dark, dry storage extends life. Heat, light, and moisture accelerate spoilage. Always follow manufacturer storage recommendations.
