Are expiration dates always reliable?

Expiration dates are not always absolute indicators of a product’s safety or quality. It’s essential to understand the difference between the “use by” date (DLC), which applies to perishable goods that may pose a health risk after a short period, and the “best before” date (DDM), which indicates when a product retains its optimal qualities.

Several factors can influence the reliability of expiration dates, including storage conditions, product handling, and the nature of the food. Inappropriate storage temperatures or damaged packaging can accelerate food deterioration, making the expiration date less reliable. Exercise good judgment and observe the appearance, smell, and texture of food, and adhere to storage instructions to minimize waste while ensuring safety.

How do storage conditions affect expiration?

Storage conditions significantly impact the expiration of various products, including food, medicines, cosmetics, and household items. Key factors include temperature, humidity, and light exposure. Inappropriate temperatures can accelerate product degradation. For example, perishable foods should be kept cold (4°C or less) or hot (60°C or more).

High humidity can promote bacteria and mold growth, reducing product lifespan. Cosmetics and household products should be stored in dry places away from moisture. Exposure to light, especially sunlight, can also degrade certain products. Proper storage, including controlled temperature, low humidity, and protection from light, is essential for maintaining product quality and prolonging expiration.

What to do with expired products?

Managing expired products involves following specific regulations and recommendations to avoid health risks and penalties. Products past their “use by” date (DLC) must be removed from sale and destroyed, as selling them is illegal and can result in fines. For products with a “best before” date (DDM), they can be sold or donated after this date, as they don’t pose an immediate health risk but may have lost some quality.

The DGCCRF recommends spraying expired products with bleach before disposal to prevent poisoning. Expired medications should be returned to a pharmacy for safe disposal and never thrown in household waste. Businesses should use expiration date management software and the FEFO (First Expired, First Out) method to manage inventory and obtain a destruction certificate for compliance.
