Why Food Labels Matter: Understanding Ingredients and Expiry Dates

Food labels have become one of the most important tools for consumer protection and public health. They provide essential information that allows individuals to make informed decisions about what they eat, how they store food, and how they manage dietary risks. As modern food systems grow increasingly complex—incorporating global supply chains, advanced processing technologies, and a wide variety of additives—clear and accurate food labelling is more important than ever. This article explores the role of food labels, focusing on ingredient lists and expiry dates, and why these elements are vital for safety, transparency, and consumer empowerment.

3. Interpreting Expiry Dates: Safety vs. Quality

Expiry dates are often misunderstood, yet they play a significant role in preventing foodborne illness and reducing food waste.

3.1 “Use By” Dates – Safety-Based

A use by date indicates the last day a food product is considered safe to consume. After this date, harmful pathogens may grow, even if the product looks or smells normal. Perishable foods such as meat, dairy, and ready-to-eat meals typically carry use by dates. Consuming products past this date poses genuine health risks.

3.2 “Best Before” Dates – Quality-Based

A best before date refers to food quality, not safety. Foods may lose flavor, texture, or nutritional value after this date but are still safe to consume if stored properly. Misunderstanding best before dates contributes significantly to household food waste.

3.3 Storage Instructions and Temperature Control

Expiry dates rely on correct storage. Labels often include guidance such as “keep refrigerated below 5°C” or “store in a cool, dry place.” Adhering to these instructions is essential for maintaining safety and extending shelf life.
