A multi-billion pound criminal enterprise lurks amid our supermarket shelves. Food crime not only harms our wallets but threatens public health. It includes activities such as mislabelling a product, replacing a food or ingredient with another substance that is inferior, and even poisoning.

This is a global concern because of how food crime is evolving. The complexity of food supply chains, the globalisation of food markets, and a lack of transparency heightens the vulnerability of the food sector. So, rethinking how we combat food crime by using technology is imperative.

Food crimes now inflict an (£31 billion) in damages globally each year. The UK’s Food Standards Agency food crime as “serious fraud and related criminality in food supply chains”.

If we think about food crime from a , we can understand its both as a way for criminals to generate dirty money that needs to be laundered, and as a means of laundering illicit funds from other criminal activities.

The food industry is particularly attractive to fraudsters because of its potential to be very . Researchers have uncovered two main approaches adopted by fraudsters in relation to .

First, they target relatively low-cost everyday foods, such as bottled water or olive oil, because these involve a large proportion of consumers, which means they can maximise profits. For example, a Spanish and Italian led to 260,000 litres of olive oil being seized. Investigators found that olive oil labelled as “virgin” or “extra virgin” had been diluted with a low-quality variant.

Another example was the , when beef products across Europe were found to contain horse meat. Such meat was more than to produce.

Alternatively, some fraudsters trick non-discerning “foodies” into paying premium prices for cheaper food dressed up as a superior product – for example, as exotic Italian truffles.

Unfortunately, our understanding of these complex financial crimes is often limited, making the detection and prevention of food fraud a .

Emerging technology

The Association of Certified Fraud Examiners, an international anti-fraud body, found that globally have used data analysis technology in response to growing financial crime risks. This technology holds promise because it can hidden patterns in vast datasets, leading to better detection and prevention of crimes.

Machine learning, for example, can analyse data and identify suspicious activity. It can also learn and adapt as new information becomes available. In the context of food crime, this could involve flagging particular locations, individuals or businesses that might pose a risk.

Evidence is limited on this topic, so we think further research needs to be conducted to analyse past food fraud cases. Identifying recurring themes and patterns using machine learning could develop a better detection model which, when combined with the expertise of regulators, food producers, distributors and retailers, could be a powerful tool.

The food industry is undergoing a potential shift, with researchers suggesting that could empower consumers to make better decisions when they buy food. Blockchain is like a secure public ledger that can’t be tampered with. So this technology offers the possibility of giving everyone from supermarket chains to individual consumers the ability to trace their food’s journey back to its origin, with ease and confidence. Imagine being able to make informed choices at the shop, knowing exactly where your food comes from.

In , the implementation of blockchain technology by some producers in recent years is expected to help address the multi-billion dollar problem of food and . A found blockchain’s data security and resistance to data corruption were important features that underlie its potential to combat food fraud.

Collaboration is key

While new technology offers promise in fighting food crime, there are to overcome. Implementing blockchain across the global food supply chain, for instance, faces including a lack of international standards and difficulty handling massive amounts of data. Blockchain technology may also require additional technology, making it expensive for small food producers.

Ultimately, the key to tackling food fraud lies in collaboration. We need to bring together law enforcement, industry professionals, organisations of all sizes and academics, each with proper ethical oversight from their institutions.

Any anti-fraud measures shouldn’t make it substantially harder for consumers to buy food. If the process becomes too cumbersome, people might find ways to circumvent it, which may create new vulnerabilities in the food system.
