28.Section 28 provides FSS the power to allow an authorised person to enter premises (other than a dwelling house), take samples and copy documents in order to monitor enforcement action. It includes a power to require any person present on the premises to provide assistance to an authorised officer which is reasonably requested. The detail of these powers is set out in the section, and the intention is to help ensure FSS has access to all the information it needs to be able to assess the performance of enforcement authorities. An authorisation issued by FSS must be made in writing and it may contain such limitations or conditions as FSS determine (e.g. hygienic precautions to be taken by an authorised officer in exercising powers under the authorisation).
