Battle against China’s fake foods drives new tech frontier

Posted by | August 10, 2017 |

A bowl of ice cream on a hot day in Shanghai gave American Mitchell Weinberg the worst bout of food poisoning he can recall. It also inspired the then-trade consultant to set up Inscatech – a global network of food spies.

In demand by multinational retailers and food producers, Inscatech and its agents scour supply chains around the world hunting for evidence of food industry fraud and malpractice.

In the eight years since he founded the New York-based firm, Mr Weinberg, 52, says China continues to be a key growth area for fraudsters as well as those developing technologies trying to counter them.

“Statistically we’re uncovering fraud about 70 per cent of the time, but in China it’s very close to 100 per cent,” he said. “It’s pervasive, it’s across food groups, and it’s anything you can possibly imagine.”

While adulteration has been a bugbear of consumers since prehistoric wine was first diluted with saltwater, scandals in China over the past decade – from melamine-laced baby formula, to rat meat dressed as lamb – have seen the planet’s largest food-producing and consuming nation become a hotbed of corrupted, counterfeit, and contaminated food.

Mr Weinberg’s company is developing molecular markers and genetic fingerprints to help authenticate natural products and sort genuine foodstuffs from the fakes.

Another approach companies are pursuing uses digital technology to track and record the provenance of food from farm to plate.

“Consumers want to know where products are from,” said Mr Shaun Rein, managing director of China Market Research Group, citing surveys the Shanghai-based consultancy conducted with consumers and supermarket operators.

Services that help companies mitigate the reputational risk that food-fraud poses is a “big growth area”, said according to Mr Rein.

“It’s a great business opportunity. It’s going to be important not just as a China play, but as a global play, because Chinese food companies are becoming part of the whole global supply chain,” he said.

Some of the biggest food companies are backing technology that grew out of the anarchic world of crypto-currencies. It is called blockchain, essentially a shared, cryptographically secure ledger of transactions.

Wal-Mart Stores, the world’s largest retailer, was one of the first to get on board, just completing a trial using blockchain technology to track pork in China, where it has more than 400 stores.

The time taken to track the meat’s supply chain was cut from 26 hours to just seconds using blockchain, and the scope of the project is being widened to other products, said Mr Frank Yiannas, Wal-Mart’s vice-president for food safety, in an interview on Thursday (Aug 3).

Shanghai-based Zhong An Information and Technology Services said in June it will use the technology to track chickens from the coop to the processing facility and on to the market or store.

Alibaba Group Holding, too, sees the potential for the eight-year-old technology to provide greater product integrity across its platforms, which accounted for more then 75 per cent of China’s online retail sales in 2015.

The planned blockchain project will involve the Chinese e-commerce behemoth working with food suppliers in Australia and New Zealand, as well as Australia Post and auditors PricewaterhouseCoopers.

“Food fraud is a serious global issue,” said Ms Maggie Zhou, managing director for Alibaba in Australia and New Zealand. “This project is the first step in creating a globally respected framework that protects the reputation of food merchants and gives consumers further confidence to purchase food online.”

Fraud costs the global food industry as much as US$40 billion (S$54 billion) annually, according to Mr John Spink, director of Michigan State University’s Food Fraud Initiative.

In China, where the 2008 melamine milk crisis resulted in the death of at least six babies, it is a hot-button issue compounded by the country’s growing appetite for higher quality food and swelling middle class.

A Pew Research Centre study last year found 40 per cent of Chinese view food safety as a “very big problem”, up from 12 per cent in 2008.

“This is not a Chinese issue – it’s a global issue,” said Mr Zhu Yongguan, director-general of the Institute of Urban Environment, part of the state-funded Chinese Academy of Sciences. “What we have to do is reinforce our regulations to improve the transparency of the administration, for example, information-sharing.”

Mr Zhu says blockchain could play an important role in improving traceability. Its database of records can be built like a chain and cannot be broken or re-ordered without disrupting the entire connection.

China strengthened its food safety law in 2015 in response to the spate of scandals. Counterfeiters and food tamperers face tougher penalties, including jail time in some cases, and more than US$800 million has been spent hiring more food safety personnel and bolstering monitoring facilities, according to an April report from the Paulson Institute, a Washington-based think tank.

Last month, Beijing emphasised to the authorities the need to be upfront in disclosing food safety issues.

“Food-fraud will always exist,” said chief scientist Wu Yongning at the government-run China National Centre For Food Safety Risk Assessment.

While the authorities in China have joined the global fight against the scourge, Mr Wu does not see the problem disappearing. “We can only develop technology to detect it,” he said. “However, fake-food producers will always update their technology to dodge inspections.”

The wiliness of fraudsters is what makes Inscatech’s Mr Weinberg less hopeful about blockchain.

His company mainly uses informants on the ground to sniff out where in the production process food-fraud is taking place, and most of his work in China is with western companies that manufacture or source for products there.

“The problem is the data is only as reliable as the person providing the data,” said Mr Weinberg, who recalls seeing everything in China from synthetic eggs to fake shrimp that still sizzle in a wok.

“In most supply chains there is one or more ‘unreliable’ data provider. This means blockchain is likely useless for protecting against food-fraud unless every piece of data is scrutinised to be accurate,” he said.

A months-long Bloomberg investigation into the global shrimp trade last year showed how unreliable documentation had fanned an illegal transhipping scheme involving Chinese aquaculture exporters.

But blockchain is “light years” away from the system used by the global food industry today, which relies heavily on paper records, said Mr Yiannas, Wal-Mart’s food safety chief.

By recording the identity of those who input data into the chain, the technology removes the anonymity that has helped food-fraud to thrive, he said.

The role of humans in recording the supply chain will also diminish, said Mr Yiannas. “More and more of these documents will eventually be captured in an automated way.”

China’s Food and Drug Administration did not immediately respond to an e-mail requesting comment on the country’s food safety efforts.

Some companies are already bringing traceability to consumers. Fonterra Cooperative Group, the world’s biggest dairy exporter, started putting QR codes on cans of infant formula in April, enabling buyers to verify the product’s authenticity.

The challenges for China – “the factory of the world” – are especially vast because of its size, population, multilayered administrative divisions, and “the willingness of criminals to exploit every corner that they can in order to make money”, said Mr Michael Ellis, who ran Interpol’s trafficking in illicit goods unit until October.

At Interpol, Mr Ellis, a former detective with Scotland Yard in London, was involved in “Opson”, an operation that led to the seizure of more than 10,000 tons and 1 million litres of hazardous fake-food and drinks across more than 50 countries.

Without a presence to fight it, food-fraud globally will explode,Mr Ellis said. “It will just continue to grow, and who knows where it will lead.”
