What Happens If a Customer Finds a Foreign Object in Their Food?
Foreign body contamination is one of the most common reasons for consumer complaints and food safety enforcement action in the UK.
Foreign body contamination is one of the most common reasons for consumer complaints and food safety enforcement action in the UK. Whether it is glass, metal, plastic, hair, insects, or other physical contaminants, finding a foreign object in food is a clear breach of food safety standards. Under Section 8 of the Food Safety Act 1990, food that contains a foreign body fails to meet the quality and substance requirements expected by the consumer. Physical contamination can cause injury, including cuts to the mouth and throat, broken teeth, and choking, particularly in children and elderly consumers. The FSA receives thousands of foreign body complaints each year, and local authorities actively prosecute businesses where contamination results from inadequate controls. Even where no injury occurs, the discovery of a foreign object in food causes significant reputational damage and can lead to a reduced food hygiene rating. For food manufacturers and caterers, robust physical contamination prevention is a fundamental requirement of any HACCP plan.
What happens next
Customer Injury and Complaint
Foreign objects can cause immediate physical harm, from cuts and choking to broken teeth. Even where there is no injury, the customer will experience disgust and loss of confidence. Expect a formal complaint, negative reviews, and potentially a claim for compensation.
Environmental Health Investigation
A foreign body complaint reported to the local authority will trigger an EHO investigation. The inspector will examine your production processes, cleaning schedules, equipment maintenance, pest control, and physical contamination controls within your HACCP plan.
Product Withdrawal or Recall
If the contamination affects a batch of products (for manufacturers or caterers producing at scale), you may need to withdraw unsold products and potentially issue a public recall. The FSA publishes recall notices publicly, amplifying the reputational impact.
Immediate Loss of Customer Confidence
A foreign body incident is viscerally unpleasant for customers. Unlike invisible bacterial contamination, a physical contaminant is tangible and often photographed. Images shared on social media create lasting negative associations with your brand.
The cost to your business
Fines
Prosecution under Section 8 of the Food Safety Act 1990 for selling food not of the substance or quality demanded can result in significant fines. Where injury has occurred, courts impose higher penalties.
Compensation Claims
Dental injuries from biting on hard objects (metal, glass, stone) can be expensive to repair. Claims for broken teeth, lacerations, and psychological distress typically range from a few hundred pounds to tens of thousands for serious injuries.
Product Recall Costs
If contamination affects a production batch, recall costs include the value of destroyed product, logistics of the recall, replacement product, and any associated testing. For manufacturers, this can run into six figures.
Reputational Damage
The financial impact of reputational damage from a foreign body incident is difficult to quantify but consistently significant. Restaurants report footfall reductions of 20-40% in the weeks following a publicised incident.
Your legal exposure
Selling Food Not of Substance or Quality Demanded
Food Safety Act 1990, Section 14
Section 14 makes it an offence to sell food that is not of the nature, substance, or quality demanded by the purchaser. Food containing foreign objects clearly fails to meet the expected quality. This is a strict liability offence.
Failure to Ensure Food Safety
Food Safety Act 1990, Section 8
Food that contains a foreign object fails to comply with food safety requirements. If the object is capable of causing injury, this strengthens the prosecution case under Section 8.
Consumer Protection Claims
Consumer Protection Act 1987 / Consumer Rights Act 2015
Customers can bring civil claims under product liability legislation without needing to prove negligence. The presence of a foreign object in food constitutes a product defect, and the business bears the burden of proof.
Foreign body contamination is a leading cause of food complaints in the UK
The FSA reports that physical contamination (foreign bodies) is consistently among the top categories of food safety complaints. Common contaminants include glass fragments from broken equipment, metal shavings from worn machinery, plastic from packaging, and pests. Local authorities prosecute dozens of businesses annually for foreign body contamination, with fines typically ranging from £2,000 to £15,000. Cases involving injury to children or repeated offences attract higher penalties.
How to prevent this
Include physical contamination as a HACCP hazard
Your HACCP plan must identify physical contamination risks at every stage of food production and preparation. Define critical control points for glass, metal, plastic, and other potential contaminants, with monitoring procedures and corrective actions.
Implement a glass and hard plastics policy
Prohibit or control glass and brittle plastics in food preparation areas. Maintain a glass register, replace glass containers with alternatives where possible, and have a documented breakage procedure.
Maintain equipment in good condition
Worn or damaged equipment is a primary source of metal and plastic contamination. Implement a preventive maintenance schedule and inspect equipment regularly for loose parts, worn blades, and deteriorating seals.
Implement effective pest control
Insect and rodent contamination requires a robust pest management programme. Use a professional pest control contractor, maintain bait station records, and conduct regular inspections of storage and preparation areas.
Train staff on physical contamination prevention
Staff should understand the sources of physical contamination, know how to inspect ingredients, and report damaged equipment or packaging immediately. Include foreign body awareness in induction training.
If it has already happened
Remove the food item and secure the foreign object
Take the contaminated food and the foreign object from the customer carefully. Preserve both as evidence. Photograph everything and record the customer's account of what happened, including any injury.
Investigate the source immediately
Determine where the foreign object came from. Check equipment for damage, review the preparation process, examine ingredient packaging, and inspect the preparation area. Identify the root cause before the evidence is disturbed.
Check for wider contamination
If the source suggests other portions may be affected (e.g. a broken glass near a prep station, a deteriorating piece of equipment), withdraw all potentially affected food. Do not serve anything you are not confident is safe.
Record the incident in your complaints log
Document the full details of the incident: what was found, in which dish, the customer's reaction, any injury, the investigation findings, and the corrective actions taken. This record will be reviewed during any subsequent inspection.
Implement corrective actions to prevent recurrence
Based on the root cause, implement specific preventive measures. This might include replacing equipment, updating your glass policy, adding visual checks at critical points, or retraining staff on contamination prevention.

Why this matters
Common questions
Can a customer sue if they find a foreign object but are not injured?
Yes. Even without physical injury, customers can claim for psychological distress and loss of enjoyment. However, claims without injury are typically much smaller, often settling for a few hundred pounds. The reputational cost of the incident usually exceeds the compensation amount.
What counts as a foreign body in food?
A foreign body is any object found in food that should not be there. This includes glass, metal, plastic, wood, stones, insects, hair, plasters, and any other physical contaminant. The severity of the offence depends on whether the object is capable of causing injury.
Do I have to report a foreign body complaint to anyone?
You are not legally required to report to the local authority, but customers often do so themselves. You should record the incident in your internal complaints log as part of your food safety management system. If you are a manufacturer and the contamination affects a batch, you must notify the FSA.
What is the "due diligence" defence for foreign bodies?
Under Section 21 of the Food Safety Act 1990, you can defend a prosecution by proving that you took all reasonable precautions and exercised all due diligence to avoid the offence. This requires demonstrating documented HACCP controls, equipment maintenance, supplier checks, and staff training specifically addressing physical contamination.
