What is date-marking information on food?
Date marking refers to the process of labelling foods with an estimated end time indicating the last date of peak safety or quality of food products. Different terms are used for dates on packages.
Some of the most common phrases used for date-marking worldwide include:
- "Use by" date. Refers to the last allowable and safe date to use or consume a product.
- Best if used by/ best-before date. Indicates the last date on which the product is at peak quality.
- "Sell-by" date. A date guide for retailers indicating the date allowed to display and sell food products.
- Expiration date. An absolute date-marking guide that tells food handlers when a food is no longer safe to be used.
- "Freeze-by" date. Refers to the last estimated date that a food can be frozen to preserve its quality.
The suitability of the date-marking term depends on the type of food being processed and the food safety regulations established in a location. Learn more about these date-marking terms from this article.
Is date-marking a legal requirement?
The U.K. food safety regulations require manufacturers to label foods with either a best-before or use by date. This regulation is under the Food Information to Consumers (FIC) and is for guiding consumers on the maximum shelf-life of a food product and highlighting the importance of food safety.
Comprehensive food safety management systems include possibilities for regular monitoring of product shelf-life or the date markings on foods.
Difference between date marking labels
Date-marking labels can sometimes be confusing for food handlers. Confusion may often lead to unnecessarily throwing away foods or contributing to causing foodborne illnesses.
Food handlers must familiarize themselves with the difference between use by and best before and other date-marking labels.
Best by vs Use by
The term "Best by" is used to refer to the date of minimum durability of the product and is used as an indicator of the ideal quality. Best by can also be presented as "Best before end (BBE)" or "best if used by."
Food businesses are only allowed to use the date-marking label if a documented risk assessment was performed on the shelf-life of the product. The assessment aims to ensure that the product will not cause any human health risk when consumers eat the product after the indicated best-by date.
Foods labelled with "best by" dates can still be consumed after the indicated time, provided that the product is not presenting any questionable characteristics.
On the other hand, "Use by" is a term used to indicate the last safe date to consume a product. As previously mentioned, this date-marking label is used on high-risk foods or those categorized as Time/Temperature Control for Safety food products.
Consuming or selling foods in the UK past their use by dates is a criminal offence as it can cause food safety issues.
What does the use by date mean?
The term Use By Date is a type of date-marking that indicates the last recommended date that a food product can be consumed at its peak safety. The meaning of this term may vary depending on the origin of the product.
The U.K. food industry categorizes it as a food safety matter. The Food Standards Agency (FSA) notes that the use by date is the most important date label to remember and advises against consuming foods past this date label.
The agency also clearly states that any food labelled with the use by-date format must not be consumed after the indicated date, even if it looks fine. The UK food safety agency advises using the use by date labelling strategy on high-risk products, such as meats, dairy products, and ready-to-eat salads.
Can you eat food on the use by date?
Foods past their use by date may be compromised in terms of food safety. The decision whether the food is safe to consume past the indicated use by date depends on many factors.
The U.K. food safety industry has a different approach to this matter. The FSA strictly discourages food handlers from using and selling foods past their use by dates. Consuming or using products past their use by date can cause severe foodborne illnesses.
This food safety guideline holds through even if the food product smells or looks okay. The food safety agency assures food handlers that the product is safe for use until the use by date, but not after.
The Food Safety and Hygiene Regulations 2013 in England lays out rules on how selling foods past their use by dates is a criminal offence.

Use by date in the U.S.
Food safety agencies in the U.S., such as the Food and Drug Administration (FDA), identify the date-marking term "use by" as an indication of acceptable quality, except when used in infant formula. This label shows the last recommended date on which the product is at its peak product quality and provides the nutrients as declared in the packaging.
Foods past the declared use by date marking are generally considered to be safe for consumption for an extended period in the U.S. The only exception to the given advice is when the label "use by" is used on infant formula products. In this case, the use by date identifies the estimated last date that the formula will provide the nutrients and safety as described.
United States federal food safety agencies advise food handlers to perform the sniff test and visual observation to decide on the suitability of the food for consumption. In some cases, even high-risk foods past their use by dates can be consumed if they are handled properly and stored correctly.
Spoiled foods will produce an unpleasant smell, discolouration, and other changes on the surface of the food. These signs will tell food handlers that the food is no longer safe for consumption.
An example of use by date
Although regulations in the U.K. and the U.S. on date labelling vary, both countries agree that use by date is a term used for high-risk foods. The use by date labelling method often depends on the country's dominant date format.
In the U.K., the use by-date format is written as day-month-year.
E.g., Use by 15 December 2023, or Use by 15-12-2023
On the other hand, the U.S. food industry may write the use by date format using month-day-year.
E.g., Use by December 15 2023, or Use by 12-15-2023
Use by dates can be written in numbers or words, depending on the discretion of the food manufacturer.
What should you do with the food past the use by date?
Uncooked foods past the use by date are advised to be not consumed and then disposed of. The risk of food poisoning or making people sick becomes significantly high once the food gets past its use by date.
If the food product was stored and held correctly before reaching the use by date, food handlers could cook the product on the indicated use by date. After cooking, the food must be refrigerated and consistently monitored to ensure safety. These food products must then either be consumed within 48 hours or frozen and properly labelled to maintain food safety.
Who has to write a use by date on the packaging?
Food companies producing or selling prepackaged foods are required to indicate a date marking, such as the use by date or the minimum durability time, on their products. This food safety law aims to guide food handlers and end users on the maximum allowable time that the food can be used or consumed.
The use by date marking is commonly used for high-risk food products that are fully or partially packed and sold to consumers.
Products that are required to have use by date label include the following:
- Fresh poultry
- Milk and dairy products
- Prepared fruit and vegetables
- Raw meat products
- Chilled, ready-to-eat foods
The declared use by dates on food products must be scientifically backed by the manufacturer's own research on the estimated shelf-life of the product.
The U.K. food safety law also provides a list of food products that do not require "use by" or "best before" dates, given that a lot number is indicated. Some of these raw materials and common food items include:
- Whole, fresh fruits and vegetables
- Alcoholic and non-alcoholic beverages made from fruits
- Baked goods that are normally consumed within 24 hours after being made
- Cooking salt
The use by dates are significant information for food handlers to maximize the potential use of their raw materials without compromising food safety. This information must be closely monitored by food handlers to avoid generating unnecessary food waste from spoiled ingredients.
In addition, monitoring the storage condition of food products labelled with "use by" date marks is also a must. The proper storage conditions will ensure that the product can last up to the indicated date label.
