Hy-Vee Tests Fresh Food Traceability with Zest Labs

Supermarket Chain Leverages the Zest Fresh Solution for Fresh Food Security and Trust Throughout its Supply Chain

San Jose, Calif. – December 20, 2017 – Zest LabsTM, a subsidiary of Ecoark Holdings, Inc. (“Ecoark”) (OTCQX: ZEST), today announced that it is working with Hy-Vee, Inc., the employee-owned supermarket chain that operates more than 245 retail stores across eight Midwestern states. Hy-Vee is conducting a trial of the company’s Zest FreshTM solution to help automate farm-to-fork traceability of fresh produce coming to Hy-Vee stores.

Hy-Vee is committed to providing a vast assortment of high-quality natural, organic and locally sourced products and empowers consumers to understand where their food is sourced.

Hy-Vee is testing Zest Fresh, the only freshness management solution that leverages the Internet of Things (IoT) to autonomously track and report in real time the freshness of products from harvest to the retail store, in its work with a premium supplier of seedless Holiday® grapes, a prized, premium product that is exported all around the world. Leveraging the industry’s first dynamic freshness metric – the ZIPR Code – Zest Fresh can provide Hy-Vee with traceability data and continuous real-time visibility of the remaining freshness capacity of the grapes.

“We are excited to work with Zest Labs to determine how Zest Fresh can help both monitor and improve freshness, while providing complete traceability through the cold supply chain,” said John Griesenbrock, Hy-Vee’s vice president, produce/Health Markets. “With traceability support, we will become even more invested in bringing the freshest and highest-quality produce to our customers.”

Zest Labs’ unique combination of secure traceability and its ZIPR Code freshness metric provides real-time data about a product’s condition and freshness capacity. As such, Zest Labs has proven to reduce waste from spoilage by more than 50 percent for grocers.

“Hy-Vee has always put high quality and consumer confidence at the forefront of everything they do, which makes them an ideal partner for us,” said Peter Mehring, CEO of Zest Labs. “By working closely with growers, we’re all creating true transparency throughout the entire cold chain and ensuring only the freshest products arrive at their stores with a complete record of the product through every step in the cold chain.”
