In the food industry, even a minor labelling mistake can become a serious problem. One of the most common and costly errors food businesses make is misunderstanding shelf life, best before and expiry dates. Many businesses assume these terms mean the same thing, but they don’t.This confusion often leads to incorrect labelling, failed inspections, rejected products and in some cases, legal action. Understanding the correct use of food label dates is not just about compliance; it is about consumer safety, brand trust and business protection.
Have you ever eaten a food product that was just past its expiry date because it looked fine or didn’t smell bad? Many consumers do this without immediate consequences, which makes expired food seem harmless.However, food safety risks are often invisible. Harmful bacteria, chemical changes and product instability cannot usually be detected by taste, smell or appearance. This is exactly why date labelling exists: to protect consumers from risks they cannot see.
For food businesses, incorrect date labelling can result in:
Shelf life refers to the period during which a food product remains safe to eat and acceptable in quality, provided it is stored under recommended conditions. Shelf life considers:Food safetyTaste, texture, smell and appearanceIngredient stabilityPackaging effectivenessStorage conditions, such as temperature and humidity Shelf life is not an estimate or assumption. It must be scientifically determined through testing and observation. This is where professional product shelf life study services in Calicut, Kerala, become essential for food businesses.
An expiry date (also called a use-by date) is the final date on which a food product can be safely consumed. After this date, the product may pose a health risk and must not be sold or consumed. Expiry dates are usually applied to:Dairy productsMeat and seafoodReady-to-eat foodsBaby foodOther high-risk or perishable productsOnce a product passes its expiry date, the responsibility lies entirely with the food business.
This is where many food businesses make mistakes.
Shelf life is the scientifically determined period during which a product remains safe and maintains quality.
Expiry date is the legally declared date printed on the label, based on shelf life testing. A business cannot legally declare a best-before or expiry date without supporting shelf-life studies. Doing so may be considered misleading or false labelling.
The best-before date relates to quality, not safety. Many dry or shelf-stable foods remain safe to eat after the best-before date, though quality may decline. The expiry date, however, is about safety. Food must not be consumed after this date. Using a best-before date where an expiry date is required is a major compliance error and can lead to serious regulatory consequences.
Many businesses print labels with “Best Before 6 Months” without testing. This is one of the most common causes of non-compliance.
Shelf life depends on ingredients, processing, packaging and storage. A competitor’s date cannot be applied to your product.
Shelf life is only valid if the product is stored under the tested conditions. If storage guidelines are unclear or untested, the label date becomes invalid.
Any change to the recipe, supplier, packaging, or process requires shelf-life revalidation. Many businesses overlook this critical step.
There are four accepted methods for determining shelf life:
Microbiological Testing – checks for bacterial growth
Chemical Stability Testing – monitors chemical changes
Sensory Evaluation – assesses taste, smell, texture and appearance
Packaging Performance Testing – evaluates how packaging protects the product For legal validity, these studies must be conducted by NABL-accredited laboratories.
