Food Fraud and Authenticity
Deliberate acts of deception in the food supply chain for economic gain, including substitution, adulteration, mislabelling, and misrepresentation of food products.
Food fraud is the deliberate and intentional substitution, addition, tampering, or misrepresentation of food, food ingredients, or food packaging for economic gain. Unlike unintentional food safety failures, food fraud is a criminal act driven by profit. It is a significant and growing concern in the global food supply chain, with the FSA estimating that food fraud costs the UK food industry hundreds of millions of pounds annually and poses real risks to public health, consumer trust, and legitimate businesses. Food fraud takes many forms. Substitution involves replacing a stated ingredient with a cheaper alternative — for example, passing off farmed salmon as wild-caught, substituting horsemeat for beef, or using a cheaper vegetable oil instead of extra virgin olive oil. Adulteration involves adding undeclared substances to food to increase its volume, weight, or value — such as adding water and bulking agents to meat products, diluting honey with sugar syrup, or adding artificial colour to spices. Mislabelling involves making false claims about a food's origin, quality, or composition — such as claiming a product is organic, British, or free-range when it is not. Misrepresentation includes selling food past its use-by date with a new label, or claiming a food product is allergen-free when it is not. The UK food fraud landscape was brought into sharp public focus by the 2013 horsemeat scandal, when horsemeat was found in beef products sold by major supermarkets and food service companies across Europe. The subsequent Elliott Review, commissioned by the UK Government and led by Professor Chris Elliott of Queen's University Belfast, made extensive recommendations for strengthening the UK's food fraud prevention framework. These included establishing the National Food Crime Unit (NFCU) within the FSA, improving intelligence sharing across the food supply chain, and strengthening penalties for food fraud offences.

Types of Food Fraud and Their Impact
Food fraud manifests in numerous ways across the supply chain. Economically motivated adulteration (EMA) is the most common form, where a food ingredient is diluted, substituted, or augmented for financial gain — examples include adding melamine to milk powder (as in the 2008 Chinese milk scandal), diluting olive oil with cheaper oils, or bulking minced beef with soya protein. Origin fraud involves misrepresenting where a food product comes from, exploiting the premium that consumers place on certain origins — such as selling imported lamb as Welsh lamb, or non-Basmati rice as Basmati. Species substitution is common in fish and meat, where a cheaper species is sold as a more expensive one — DNA testing has revealed that a significant proportion of fish sold in UK restaurants and takeaways is not the species stated on the menu. Organic fraud involves selling conventionally produced food as organic to command higher prices. Document fraud involves forging or altering certificates, test results, or traceability records to disguise the true nature of food products. The public health impact of food fraud can be severe — undeclared allergens, banned veterinary drugs in substituted meat, or toxic adulterants can cause illness or death.
Due Diligence and Supply Chain Integrity
UK food law places a due diligence obligation on food businesses. Under Section 21 of the Food Safety Act 1990, it is a defence for a person charged with a food safety offence to prove that they took all reasonable precautions and exercised all due diligence to avoid the commission of the offence. In practice, this means food businesses must have robust systems for verifying the authenticity and safety of the food they buy and sell. For hospitality businesses, this includes knowing your suppliers (conducting checks, visiting premises, reviewing their food safety certifications), maintaining traceability records (being able to trace every ingredient back to its source and forward to the customer), verifying product descriptions (checking that what is delivered matches what was ordered), conducting periodic authenticity checks (particularly for high-value or high-risk products such as fish, meat, olive oil, spices, and organic products), and reporting suspected food fraud to the NFCU or local authority. The Elliott Review recommended a "farm to fork" approach to food integrity, with every link in the supply chain taking responsibility for ensuring the authenticity of the products they handle.
The National Food Crime Unit and Enforcement
The National Food Crime Unit (NFCU) was established within the FSA in 2015, following the recommendation of the Elliott Review, to lead the UK's response to food fraud and food crime. The NFCU has intelligence-gathering, investigation, and enforcement powers, and works closely with local authority trading standards, police, and international agencies such as Europol and Interpol. Food fraud can be prosecuted under a range of legislation including the Food Safety Act 1990 (particularly Section 14, selling food not of the nature, substance, or quality demanded, and Section 15, falsely describing or presenting food), the Fraud Act 2006, the Consumer Protection from Unfair Trading Regulations 2008, and in serious cases, the Proceeds of Crime Act 2002. Penalties can include unlimited fines and imprisonment. The FSA operates a food crime reporting hotline (0800 028 1180) and an online reporting form, and encourages anyone who suspects food fraud — whether they are consumers, industry professionals, or whistleblowers — to report it. Businesses that discover food fraud in their supply chain have a responsibility to report it and take action to remove affected products.
Frequently Asked Questions
How does food fraud differ from food safety failures?
Food safety failures are typically unintentional — they occur when a business fails to follow proper hygiene procedures, resulting in contamination or unsafe food. Food fraud is deliberate and intentional — it involves knowingly deceiving customers or other businesses about the nature, quality, or origin of food products for economic gain. Both can result in food that is unsafe to eat, but the intent is fundamentally different. Food fraud is investigated as a crime, while food safety failures are typically addressed through the graduated enforcement system.
What should I do if I suspect food fraud in my supply chain?
Report your suspicions to the National Food Crime Unit via the FSA's food crime reporting hotline (0800 028 1180) or online form, or to your local authority trading standards team. Preserve any evidence including packaging, labels, delivery notes, invoices, and samples of the suspect product. Do not destroy or return the product to the supplier before reporting. Review your supply chain to identify any other potentially affected products and consider suspending purchases from the suspect supplier until the matter is resolved.
What foods are most commonly subject to fraud?
Foods that command a premium price or where there is a large price differential between the genuine product and a potential substitute are most vulnerable. In the UK, the most commonly reported food fraud categories include fish and seafood (species substitution), meat products (species substitution, origin fraud), olive oil (dilution with cheaper oils), honey (adulteration with sugar syrup), herbs and spices (bulking with fillers, artificial colouring), organic products (conventional products sold as organic), and wine and spirits (counterfeiting, dilution).
What is the due diligence defence?
Section 21 of the Food Safety Act 1990 provides a defence for a person charged with a food offence if they can prove that they took all reasonable precautions and exercised all due diligence to avoid the offence. For food fraud, this means having robust supplier approval systems, maintaining traceability records, conducting periodic checks on high-risk products, and acting promptly when any concern is raised. Businesses that can demonstrate a comprehensive due diligence system are better protected both legally and commercially.
Was anyone prosecuted for the horsemeat scandal?
Yes, although prosecutions took several years. In 2017, two directors of a Dutch meat trading company were convicted of fraud and sentenced to prison terms. In the UK, three men were convicted in 2018 of conspiracy to commit fraud in connection with the mislabelling of horsemeat as beef. Andronicos Sideras, the owner of Dinos & Sons Ltd, was sentenced to four and a half years in prison. The horsemeat scandal exposed significant weaknesses in supply chain oversight and led to fundamental reforms in food fraud prevention, including the establishment of the NFCU.
