Recognise the importance of date marking of foodstuffs and when lot marking is necessary
This guidance is for England
Most prepacked foods must be marked with either a use-by date or a minimum durability date. (Prepacked food is food that is completely or partially enclosed in packaging, cannot be removed without changing the packaging in some way, and was packed on a premises other than the one it is being sold from.)
Food business operators (FBOs) can change the durability indication if necessary; they then become responsible for the accuracy of any changes that they make. This enables, amongst other things, FBOs to freeze a product if it is appropriate to do so. An FBO that freezes a product needs to indicate the new durability date and give the appropriate conditions of use and storage instructions. (An FBO is any business involved in the manufacture or supply of food for human consumption, and includes retailers.)
Regardless of which type of date marking is used you can replace the date with a statement of where the date may be found on the packaging - for example, 'Best before - see base of pack'.
Most prepacked foods must also carry a batch and/or lot number so a product can be traced if necessary.
Food that is highly perishable and therefore likely to pose a danger to human health after only a short time should be marked with a use-by date.
Examples of food that should have a use by date include:
The use-by date should be given in the format 'Use by: day / month' - for example, 'Use by: 23 January'.
You may add the year if you wish.
The date must be given in the order day, month, year, and be uncoded. Write the month rather than using numbers (06 for June, for example) to prevent confusion; '05/06' could mean 5 June or 6 May.
If the product is made up of a number of individually prepacked products, the use-by date must appear on each.
There are two types of minimum-durability date - 'best before' and 'best before end' - and which one you need to use will depend on the life of the product.
If there are certain storage conditions that have to be followed for the food to last until the given date then this must be stated on the packaging.
Other date markings, such as 'display until', do not have any legal standing and are confusing to consumers; such date markings should not be used, except in the case of eggs (see below).
FOODS WITH A SHELF LIFE OF THREE MONTHS OR LESS
'Best before: day / month' - for example, 'Best before: 23 January'.
You may add the year if you wish.
FOODS WITH A SHELF LIFE OF BETWEEN THREE & 18 MONTHS
These should be marked with either 'best before' or 'best before end' as follows (your choice).
'Best before: day / month / year' - for example, 'Best before: 23 January 2018'
'Best before end: month / year' - for example, 'Best before end: January 2018'
FOODS WITH A SHELF LIFE OF GREATER THAN 18 MONTHS
'Best before end: Year' - for example, 'Best before end: 2018'
Foods marked with a use-by date must not be sold or displayed for sale after their marked dates. It is an offence to sell or offer for sale food past its use-by date. For example, 'Use by 23 January' means use by midnight on 23 January; if on display after midnight an offence has been committed.
Foods marked with best-before or best-before-end dates may be sold after their marked dates, provided that they remain of good quality and are fit for human consumption. In these circumstances it is advisable to ensure that customers know that the date has expired before they make the decision to buy. The manufacturer is responsible for the quality of the product until the stated best-before / best-before-end date; if the retailer chooses to amend the date, or sell the product after the stated date, they must then take responsibility for the quality of the product.
The only exception to the above is eggs, which must be removed from sale by their sell-by / display-until date, or, if this is not stated, seven days before their best-before date. See 'Retail sale & labelling of eggs' for more information.
The date marking on prepacked foods should be clearly legible, easily visible and indelible; it should not be obscured, or partly obscured, by price stickers or in any other manner.
Good retail trading practice:
Most prepacked foods intended for human consumption must carry lot or batch marking (unless specifically exempted). This is to enable a product to be traced and/or recalled if necessary, with the maximum efficiency.
It is not necessary for the consumer to understand the lot / batch mark provided the indication can be clearly identified. The mark may have to be prefixed by the letter 'L' if it is not clearly distinguishable from other information (such as the use-by date or minimum durability marking) and must be clearly visible, clearly legible and indelible.
Lot marking should be visible on the exterior packaging, such as where retail packs are sold wholesale in boxes or shrink-wrapped trays.
Where individual products sold at retail level are sold in additional packaging (for example, whisky in a presentation box) it is good practice to put the lot marking on the external retail packaging (the box) as well as the label of the bottle on the inside. This is so that the correct items can be identified for recall without opening all of the individual boxes.
Bearing in mind any possible need for a product recall, the manufacturer / packer must decide on the size of the batch to be given the specific lot mark. Large batches could result in more products having to be recalled than is perhaps necessary.
Where a product bears a date mark that consists of at least the day and the month (in that order) this may provide sufficient batch identification to serve as the lot mark (dependent on the volume of product and frequency of production). If not, a separate lot mark must be given.
Frozen meat, frozen meat preparations and frozen unprocessed fishery products require a declaration of the date of freezing (or the date of first freezing in cases where the product has been frozen more than once). It shall be preceded by the words 'Frozen on …' followed by an uncoded indication of the day, month and year in that order, or a reference to where on the label such a date can be found.
Failure to comply may result in an improvement notice being issued, requiring compliance to be achieved. If the improvement notice is not complied with it is an offence under the Food Safety Act 1990. The maximum penalty is a fine and two years' imprisonment.
If food is sold after the use-by date it is an offence under the Food Safety and Hygiene (England) Regulations 2013. The maximum penalty is a fine.
