A foreign body complaint is any incident in which a customer says they have found something in their food that should not be there — glass, plastic, metal, hair, insect, fragment of bone in a boneless dish. The next 60 minutes decide whether this becomes a managed incident with a one-line note in the file, or a closure with a prosecution at the end of it. The default UK regulatory expectation, under your food safety management system, is that you quarantine, document, notify and prevent — in that order, every time. If you do not yet have a rehearsed response, our emergency food safety support can stand alongside you through the next 24 hours.
Step 1: Believe the Customer, in Public
The single most expensive mistake managers make is arguing with the customer at the table. The legal point — whether the foreign body actually came from your kitchen — will be resolved later, by you, calmly, with records. The customer-service point — whether they leave feeling heard or post a one-star review — is resolved at the table in the next two minutes. Apologise that they have had an unpleasant experience, take the item if they will give it to you, place it in a clean container and walk away with it before anything else happens.
Step 2: Quarantine the Batch
Whatever dish the foreign body came from, every portion in your kitchen made from the same prep batch, ingredient or supplier code goes into quarantine. That means physically separated, labelled "DO NOT USE — INCIDENT [date]", and removed from the line. The same batch served to the next customer is how a complaint becomes a cluster.
Step 3: Document While It Is Fresh
Open an incident log — paper or digital — with: time the complaint was made, customer name and contact details, dish and table number, server who took it, manager who responded, exact description of the foreign body, photographs of it in good light against a plain background, supplier batch information for every component, and what action you took next. This is your due diligence evidence; without it, the legal defence available under the Food Safety Act 1990 becomes much harder. Our guide to food safety due diligence explains what the standard actually requires.
Step 4: Decide Whether to Notify
You must notify your local authority promptly if you know or have reason to believe food you have placed on the market is unsafe — typically meaning hard or sharp foreign bodies that could injure, biological contamination, or any case where multiple customers are affected. A single soft hair on one plate is a complaint to resolve internally; glass shards in a soup is a notification. When in doubt, call your environmental health team — being the one who reports it is a fundamentally different position from being the one who is reported.
Step 5: Investigate the Source
- Walk the production path of that dish, item by item, and check each potential source: blades, oven racks, packaging, supplier raw material, dishwasher seals.
- Talk to the staff involved without blame — accurate accounts come from people who feel safe speaking.
- Pull supplier records: batch, delivery date, and any prior complaints linked to that code.
- Check the foreign body against the dish: a fragment of clear plastic in a sauce that uses no clear plastic packaging probably came from outside your kitchen.
Step 6: Prevent Recurrence
Every incident must close with a documented change: a new check, a piece of equipment retired, a supplier escalated, a refresh of training. The closing note in your incident log should answer the question "what is now different so this cannot happen again?" If you cannot answer it, the file is not closed. Our food safety consulting service helps build the lessons-learned process into your management system rather than leaving it on a shelf.
Train So the Response Is Automatic
A team that has rehearsed this once will execute it under pressure. A team that has not will argue with the customer, throw the item in the bin and serve the rest of the batch. Our Level 2 Food Safety and Hygiene course covers incident response alongside hygiene basics — pair it with a 30-minute table-top scenario every six months and the response becomes muscle memory.
When the Press, Council or Insurer Calls
Refer all media enquiries to one named person — usually the owner. Co-operate fully and openly with your local authority; the inspector will be far more constructive with a manager who has the incident log open in front of them than one who is "still gathering the facts" two days later. Notify your insurer immediately for anything that might lead to a personal injury claim, however unlikely it seems on day one. Our EHO inspection preparation guide covers what officers expect on an unannounced follow-up visit.
Frequently Asked Questions
Should I refund the customer immediately?
Almost always yes — and offer a clear next step (replacement, account credit, an apology call from the owner). The cost of the meal is trivial compared with the value of resolving the situation while they are still in the building.
What if the foreign body looks like it came from the customer?
Investigate exactly the same way. You may conclude internally that the source was the customer (a strand of their own hair, for example), but do not say so at the table; resolve the immediate situation and document the finding privately. Public arguments turn into reviews and complaints to the council either way.
How long should I keep incident records?
A minimum of two years is good practice, longer if the incident led to any external complaint or claim. Records are what supports a due-diligence defence; throwing them away is throwing the defence away.
