A new economic model reveals how a relatively small number of organized food fraud schemes can impose huge costs, while industry quality controls may be keeping much of the UK food supply protected.

A recent study in the Journal of Economic Criminology developed a model described as the first attempt to measure the total annual economic cost of food fraud in the UK and analyzed its primary cost drivers.
Why the True Cost of Food Fraud Remains Hidden
While fraud now accounts for nearly half of all crimes against individuals in the UK, its true impact has long been overshadowed by criminology’s focus on violent crime. The Crime Survey for England and Wales first included fraud in 2016, revealing that millions are affected each year. Despite this, police resources remain disproportionately low, and the broader social consequences are often underestimated.
This is especially evident in food fraud, a form of deception in which food is deliberately misrepresented for financial gain. Food fraud takes many forms, including adulteration, substitution, misrepresentation, and document fraud. Its effects are far-reaching: consumers are duped, legitimate businesses suffer financial losses, and public health is put at risk. Notably, high-profile scandals like the UK “horse meat scandal” illustrate the seriousness of the problem, yet food fraud continues to receive little attention.
Existing research predominantly focuses on direct victim losses and struggles with inconsistent methodologies and poor data, resulting in widely varying cost estimates. Critically, food fraud remains a hidden crime, with few comprehensive studies addressing its full economic, social, and health impacts. This persistent research gap means policymakers lack the evidence needed to allocate resources or implement effective interventions. There is a clear need for targeted research to capture the true scale and broader consequences of food fraud, in order to protect consumers and the integrity of the food industry.
Assessing the Cost of Food Fraud in the UK
This study estimated the cost of food fraud in the UK by constructing a synthesis-based model using multiple data sources. Given the lack of centralized records, the research team gathered data by web-scraping 221 media-reported UK food fraud cases, 90% of which occurred after 2008, and manually reviewing each to estimate costs. Insights from industry and regulatory interviews further indicated that smaller businesses were perceived as more vulnerable to food fraud because they often lacked robust quality controls.
Four main crime cost estimation approaches were reviewed: counting (incident tallies and direct losses), typology (costs by category), econometrics (willingness to pay for intangible impacts), and synthesis (combining multiple methods for a holistic view).
For food fraud, the synthesis approach was selected as it integrates multiple data types and methods, addressing gaps in official reporting. While previous major studies estimated total UK crime and fraud costs, food fraud was notably excluded from these assessments.
Various techniques were considered, including fraud loss measurement (FLM), which audits transaction sets to estimate fraud rates, and the Annual Fraud Indicator (AFI), which estimates UK direct fraud losses at £219 billion using a typology-based approach.
To account for underreporting, a multiplier was applied, based on the estimate that only 20% of small-business victims report food fraud. Using an FSA-provided figure of 610 incidents reported to authorities in 2021 as the lower bound, this yielded an estimated annual crime rate of 610–3,050. The cost model, developed using the synthesis approach, divided costs into five categories - victim, justice system, crime career, market, and prevention - and used market prices, health data, and theoretical models to quantify direct and indirect impacts. Crucially, the model treated an offender’s crime scheme, rather than an individual victimization, as the unit of analysis, allowing a single scheme to encompass multiple victims over time.
Food Fraud Impact on the UK Economy
The analysis of unit cost data showed a strong imbalance: most cases involved small losses, while only a few accounted for large, high-profile amounts. This pattern, typical in fraud, was intensified by media-based data collection, as the media tended to highlight only the most sensational, high-value incidents.
To reduce bias, cases were grouped into minor (losses below £100,000, making up about 87%) and major (losses over £100,000 or involving death, about 13%). The weighted average cost was calculated to better reflect this distribution.
The annual cost of food fraud was estimated by multiplying the weighted unit cost (£634,316 per crime scheme) by yearly crime rates. Social harm, which incorporated victim costs, crime costs, and market costs, made up the largest share. Including prevention costs, the total annual impact in the UK ranged from £410 million to nearly £2 billion. The novel market-cost component, which estimated welfare losses from fraudulent products crowding legitimate goods out of the market, accounted for less than 0.1% of total costs.
Most losses directly affected businesses and individuals. Government spending on justice, prevention, and regulation accounted for a much smaller share, highlighting the concentration of the financial burden. However, private-sector fraud-prevention costs could not be reliably separated from broader quality-control expenditure.
Businesses bore the largest share of food fraud losses (about 68%), compared to government (17%) and individuals (15%). This reflected the entrepreneurial nature of offenders, typically organized enterprises competing with legitimate firms, including wholly illicit traders and otherwise legitimate businesses drawn into fraudulent activity. Government costs were mainly for enforcement and regulation, while individuals accounted for a smaller share of the overall loss.
Conclusions
Food fraud placed a significant economic burden on the UK, with annual costs estimated between £0.4 billion and £2 billion. Despite these costs, the study found food fraud relatively rare compared with other fraud, particularly in the large-business sector, where overlapping quality controls help protect supply chains.
However, accurately measuring crime rates and keeping pace with evolving fraud schemes remain challenging. Overcoming these obstacles calls for better data collection, clearer national counting rules, and further research involving local authorities, small businesses, and consumers. The authors estimated that food fraud prosecutions could yield an economic return above 400%, although this projection was based on a limited sample and requires further research; they also emphasized the importance of industry quality controls in safeguarding market integrity.
