Food defence through the eyes of a mystery guest
Validate the effectiveness of your food defence system with a mystery guest. This service helps you ensure that the measures in place effectively keep unauthorised individuals out and that your team understands how to respond in unexpected situations. The strength of your food safety culture plays a crucial role in maintaining a secure environment.
A mystery guest assessment offers valuable insight by testing the system in practice. It highlights gaps, confirms what's working, and provides clear direction for further improvement.

Food defence
Food safety is receiving increasing attention, making it essential for food businesses to strengthen their defences against potential threats. Standards such as BRCGS Food, IFS Food and FSSC 22000 require companies to establish an effective food defence plan. One innovative way to assess the strength of these measures is by deploying a mystery guest.
The role of a mystery guest
A mystery guest is a trained professional who poses as a customer, supplier, or temporary employee to identify vulnerabilities in your organisation’s Food Defence plan. This includes assessing visitor management, access controls to sensitive areas, and procedures around production and storage zones. Discreet and realistic in their approach, the mystery guest simulates everyday scenarios, for example, attempting to access a production hall to observe whether staff respond appropriately to suspicious behaviour. These assessments are always carried out with your prior approval. Afterwards, the mystery guest delivers a detailed report with findings and recommendations, enabling you to take targeted action to further strengthen security.
Advantages of a Mystery Guest
A visit from a Mystery Guest offers various advantages:
Reality check: A Food Defense plan on paper is valuable, but the real test is in practice. The Mystery Guest investigates whether the procedure is truly effective.
Increased awareness: Staff are more alert because they realize that security can be actively tested.
Objective evaluation: A Mystery Guest looks at the situation with a fresh pair of eyes and exposes blind spots in the daily work routine.
A unique opportunity
By deploying a mystery guest, we offer companies a unique opportunity to strengthen their security against deliberate threats. By identifying weaknesses and evaluating measures, this method contributes to a safer food chain and increases organisations' resilience against attacks.
Improve your food defence plan
After the mystery guest's visit, we record the findings and discuss the results. If you follow this advice, it will lead to a stronger food defence plan. We also offer support in implementing improvements. You can repeat the mystery guest visit annually to assess the progress and effectiveness of the plan. The findings also provide valuable input for a training course on food defence. This can be combined with the mystery guest visit to increase both awareness and skills.
