Better links in the chain

Ensuring food safety, quality and transparency through blockchain technology

With today’s increasingly complex supply chain, brands face an ever-growing challenge to ensure only the best and safest version of their products reach consumers.

Food products see many handlers between creation and distribution before even reaching the consumer, which naturally incites more opportunity for quality and safety issues, to occur—potentially leading to recalls and other major health concerns.

In fact, the U.S. Food and Drug Administration and the U.S. Department of Agriculture’s Food Safety and Inspection Service, recorded a total of 456 food recalls in the U.S. in 2017.

Other challenges lie in assuring proper documentation of each step of the supply chain. Without these measures, information can get lost and severely compromise a brand’s image.


The current supply chain system does not always allow consumers and other stakeholders to distinguish the true value or origin of food products adequately. Without assigning dedicated, traceable values to these products, it can be difficult for third parties to verify at what point in the supply chain the issue may have arisen.

However, the recent emergence of so-called blockchain technology is showing a lot of promise in addressing this issue. In fact, nearly six out of 10 large corporations are currently considering using blockchain.

As consumers and participants in the supply chain demand greater transparency, blockchain has the potential to transform how information about a food product flows from farm to fork—to ensure quality and safety by adding greater visibility and efficiency to the process.

Originally developed as an accounting method for the virtual currency Bitcoin, blockchains are cropping up in various commercial applications today as a way to verify the authenticity of products or goods.

Blockchain is a digitized, continuously growing list of records or blocks, which are securely linked using cryptography. After completing a block, the technology produces a new block while permanently securing the old in linear, sequential order—similar to links in a chain. Each block contains cryptographic information from the preceding block, a time-stamp and transaction data.

By design, the technology is immutable or inherently resistant to data modification or deletion, as every block links to the one before and after it.

Blockchain technology has the potential to change the way we purchase, sell and make transactions for goods and services. By combining ease-of-use and the security of cryptography, blockchain can be used for any exchange, agreements or contracts, as well as making and tracking payments.

In short, it allows the supply chain community to verify and monitor the entire process.

Blockchain has the potential to serve as a highly beneficial tool for the food industry. Food products change hands numerous times across a supply chain: from ingredients manufacturers to processing facilities, to packaging operations—sometimes co-packers—packagers—to shipping and distribution, and, finally, retail.

Even then, a growing e-commerce market adds an additional layer of complexity when products are shipped from the retailer to the consumer. With blockchain, each transaction can be recorded and later viewed in a permanent decentralized repository—reducing potential delays, added costs, and the risk of human error.

For example, should an issue arise with a food product, users with system access can pinpoint where the problem originated and react accordingly, saving precious time that could otherwise see major harm to consumers’ health and a brand’s image. Once the manufacturer identifies the source of the problem, the food company can adjust their recall, selecting only the items that were afflicted and posed a risk.

This step ultimately saves costs of scrapping an entire run or order of a product that was not compromised by the error.

Additionally, faster reaction times are possible because supply chain information is readily available in the decentralized system. Rather than spending weeks attempting to identify where an issue arose, stakeholders can receive the necessary information within one to several days and respond accordingly, minimizing damage.

Although a key benefit of blockchain is its immediate depiction of data and information, another critical benefit is its added security. The technology enables companies doing business with each other to record transactions indelibly.

Blockchain’s key strength lies in its trustworthiness, as it is impossible to reverse or change what has been recorded.

With blockchain, brands can not only rest assured that their data is safe, but can also build trust with their customers. The technology is designed to provide even greater visibility into the complex steps of the supply chain, which enhances brands’ ability to meet consumer demand for more information about their products or to meet government regulations. Authenticating a product’s journey across the supply chain reveals its exact origin and history, which can help to substantiate product claims and, ultimately, build trust.

To learn more about how food brands can boost safety, quality and transparency through the use of blockchain technology, progressive food manufacturers should will do themselves a big favor by attending next month’s PACK EXPO International 2018 packaging and processing technologies trade show, Oct.14-17, 2018, at the McCormick Place in Chicago, to get their blockchain journey started.
