Vivien is part of a growing cohort of consumers who want to be able to trace the sources of the food they feed their families all the way back to the farm. Mintel, a global market research company, named traceability鈥攖he ability to see where food comes from, what it鈥檚 made with, and by whom鈥攐ne of the five most important food and drink trends for 2018. According to Mintel, the trend is fueled by 鈥渨idespread distrust鈥 in how our food is made, the 鈥渘eed for reassurance about the safety and trustworthiness鈥 of food, and the increasing use of natural, ethical and environmental claims on packaging. While more recent data from Mintel is not available, other consumer research points out that over half of consumer purchases are driven by health, safety, social impact and experience鈥攁ll of which require transparency and traceability.
Smart labels
These changes in consumer鈥檚 expectations can be seen most vividly in the so-called 鈥渓ocavore鈥 movement. Thanks to a greatly shortened supply chain, when a consumer buys beets at her town鈥檚 farmer鈥檚 market, she knows just where to turn if there is a problem. The consumer feels good about the purchase for many reasons: local food is perceived to be safer, more environmentally friendly, more supportive of the community鈥攁nd more trustworthy. While 鈥渓ocal鈥 is an undefined term鈥攊t can mean anywhere between forty and four hundred miles鈥攊t resonates with consumers as being higher quality, fresher and more authentic. The local food market in the U.S. topped $9.1 billion in 2020.
Most consumers, however, are unlikely to buy all their food from local sources. You鈥檇 be hard-pressed to find a New Yorker willing to forgo his leafy green salad in winter or a Midwesterner who will do without avocados from Mexico or blueberries from Chile. But the supply chains for these foods can stretch thousands of miles and up to a year or more. And problems like the five deaths caused by romaine lettuce tainted with E.coli bacteria issue this summer only heighten consumers鈥 fears about the food they buy.
Current traceability practices dictated by federal regulations require each step in the supply chain to generate its own records鈥攁nd since 2010, every produce industry stakeholder must also track and keep data on 鈥渙ne step forward, one step back.鈥 In its simplest iteration, that requires a farm to have in place a system that allows the grower to track the produce from the field (one step back) to the buyer (one step forward). While the system should make nailing down the source of an outbreak easier, it is still incredibly cumbersome and time-consuming鈥攁nd often, in the complex global food supply web, far from linear. Streamlined traceability, however, can greatly reduce the need for old-fashioned detective work like physically scouring fields and inspecting supermarkets.
It鈥檚 difficult enough to create such a system for domestically grown produce. But it is especially challenging with globally sourced foods; regulations concerning record keeping, allergens, pesticides, and more vary greatly by country, as does enforcement. Our 鈥減erfect world鈥 scenario requires a level of alignment and cooperation that spans every step of the food system and has no political borders.
In food we trust
How far away are we from this vision of traceability? Current and emerging technology may actually make it possible to trace produce at a level of detail and accuracy far beyond what we鈥檙e capable of today.
The robotics, mobile computing and networks of the Internet of Things (IoT) will ultimately allow us to collect and tie together data throughout the supply chain. All the food we buy would have a transparent set of interconnected tech-enabled checkpoints that consumers could gain insight into. Ideally, each individual unit of produce harvested would be assigned traceable data points indicating the farm and location, a lot number to show the specific field where it was grown, the date of harvest, the workers who harvested it, the date and location where it was packed, the workers who packed, to whom the lot was sold, how and by whom it was transported, the temperature and humidity conditions under which it was transported, and how and to whom the produce was distributed. Did that particular head of broccoli get sent directly to a supermarket, or to a distribution center, where more people handled it?
The question then arises: with whom is all this data entrusted? In fact, the distributed ledger system used to power bitcoin, called blockchain, may be the answer.
Companies including Dole, Driscoll鈥檚, Nestle, and Wal-Mart are betting the farm, so to speak, that consumers鈥 need for reassurance through traceability will fuel their buying decisions. These industry giants, along with others, have joined forces to create a food tracking blockchain they鈥檙e calling the Food Trust. The IBM-built blockchain monitors transactions and keeps records to create one consistent history. Think of it like FedEx tracking a package鈥攖he item itself is followed with consistent, accurate data.
A number of agricultural companies are working to engage a variety of partners in the food and agriculture industry to better leverage blockchain for their customers鈥 benefit. This technology provides a token at the point of food creation and follows it all the way through to the final consumer selling point. By the time a consumer picks up the item in a grocery store, it comes complete with a detailed story鈥攆rom farm to table.
鈥淐onsumers like our imaginary Vivien have grown accustomed to getting fresh fruit and vegetables year-round. New traceability technologies will soon give consumers across the globe renewed confidence to buy what they want, whenever they want it. That won鈥檛 just benefit shoppers like Vivien. It will increase the marketability and value of their crops, not to mention giving a boost to other players in the food chain who have a stake in the safety of the food they produce and distribute.鈥
