The roles and responsibilities of authorised food officers, including taking of food samples
This guidance is for England
Local authorities are required to enforce the provisions of the Food Safety Act 1990, as well as regulations made under it and other acts. Food composition and labelling is controlled by these pieces of legislation and makes certain things criminal offences - for example, it is an offence to sell food that:
Food should always be of the quality the consumer is expecting to receive; low quality food is not a problem as long as the customer knows that is what they have paid for.
Enforcement action will often come after formal food samples have been taken (in this case food means both food and drink).
Formal samples may be taken for various reasons, including:
If a sample is incorrect there are several possible courses of action that can be taken:
An improvement notice will require the person receiving it to take specified corrective action within a certain time. Failure to comply with the notice is a criminal offence.
Anyone receiving a simple caution will have to sign to accept responsibility for the offence having been committed; there is no further penalty but it is considered to be a criminal conviction. If a simple caution is not accepted the local authority will proceed with a prosecution.
The action taken will depend upon, for example:
Procedures for sampling are strictly controlled by specific regulations and codes of practice. This legislation gives authorised officers the power to purchase or take food samples at all reasonable hours; in other words, when the business is operating and staff are on the premises. Failure to allow an authorised officer to take a sample could lead to the commission of an obstruction offence.
Please note that the requirement for trading standards officers to give two days prior written notice of the intention to visit - as outlined in 'Trading standards: powers, enforcement and penalties' - does not apply to food legislation.
Formal food samples will generally consist of either one or more food items mixed together and split into three identical parts, or multiple food items that are distributed between the three parts of the sample but the food items themselves are kept whole. The method of sampling will depend on the product and what is being tested for.
The three parts are distributed as follows:
The reason for the division of samples, is to allow potential defendants the opportunity to have their own sample portion analysed if the results from the public analyst reveal a problem. If you have manufactured or altered the food, or applied the description that is being tested to the food, you may be responsible for any criminal offence. If you are a retailer that is only selling food in the same state in which it was supplied to you, your supplier or the manufacturer may be the responsible person.
The sample portion kept by you is very important and should be stored safely until you receive notification of the analytical results.
It is important that you do the following:
If there is a dispute over the analysis, the final portion is sent to the laboratory of the Government Chemist, which has the final say on the result.
The sampling officer must check the Primary Authority website to find out if the business has a Primary Authority partnership. If a partnership exists the officer must notify the Primary Authority about any proposed enforcement action; if the local authority fails to make the notification the Primary Authority may block the proposed enforcement action. See our guide 'Primary Authority' for more information on these partnerships.
Storage of sample portions
Where you are given a portion of a sample to retain, you should keep this frozen or stored at ambient temperature, depending on whether the product is likely to deteriorate. As a rule, fresh food such as meat and dairy products will need to be kept in the freezer. Dried products such as rice, spices, nuts and other goods stored at room temperature should continue to be stored as per the instructions on the packaging to prevent deterioration.
Occasionally you may be given specific instructions by the sampling officer, and you should follow their guidance - for example, if fresh food is being sampled to check whether it has been previously frozen.
A three-part sample will be taken whenever possible. In some circumstances, however, the sampling officer will need to take a single-part sample. Where a single-part sample has been taken there will be no part for you to retain.
Examples of when a single-part sample will be taken include:
A complaint sample is when a member of the public complains about a food that they have purchased (perhaps it caused an allergic reaction or was not as described) and the officer takes the remaining food as a sample. Complaint samples are never divided and are submitted for analysis in the state that they were received. The sampling officer must notify you that the sample has been submitted for analysis and may visit you to take a further three-part sample from your remaining stock.
