Cal-Maine Foods’ longstanding investment in advanced biosecurity capabilities helps protect its operations and support a safe, reliable food supply.

OVERLAND PARK AND CHASE, KS / ACCESS Newswire / October 12, 2026 / U.S. Senator Roger Marshall, M.D., recently visited the Cal-Maine Foods facility in Chase, Kan. to learn firsthand how the company takes a layered approach to biosecurity and food safety, which includes Synexis DHP® technology for proactive, continuous pathogen control.

Senator Marshall’s visit followed his recent tour of Synexis headquarters and provided an opportunity to see DHP technology deployed in an egg production environment, a method of continuous microbial reduction that works alongside established sanitation, food safety, and biosecurity practices.

Since 2018, Cal-Maine Foods has proactively deployed DHP technology across more than 40 egg processing facilities nationwide, demonstrating the company’s longstanding commitment to investing in technologies and operating practices that reduce risk and strengthen the reliability of its operations.

Synexis DHP technology converts ambient oxygen and humidity into trace levels of hydrogen peroxide gas that continuously flows throughout enclosed indoor environments to reduce airborne and surface-level pathogens. Cal-Maine Foods counts on Synexis technology because it operates continuously without disrupting operations or requiring additional labor and is USDA Organic* permitted, residue-free, and safe for use around people, animals, products, and equipment.

For Senator Marshall, seeing Cal-Maine Foods’ layered pathogen control strategy firsthand underscored the broader importance of biosecurity to agriculture, food safety, and supply chain resilience.

“Thank you to Cal-Maine and Synexis for having me out to visit. It was great to see firsthand the work they’re doing to keep our egg supply safe and healthy, and I’m glad to see them investing in new biosecurity technology to protect their flocks and keep Kansas agriculture and the American supply chain strong,” said U.S. Senator Roger Marshall, M.D.

“Reliability matters enormously to our customers and to the consumers who depend on the food we produce,” said Sherman Miller, President and Chief Executive Officer of Cal-Maine Foods. “That requires us to continually invest in our operations, adopt technologies that can make us better, and maintain rigorous standards across our network. Synexis is one example of how we continue to strengthen those capabilities.”

“Biosecurity is most effective when it is approached as a system of complementary measures rather than a single intervention,” said Dennis Doyle, Chief Executive Officer of Synexis. “We’re proud that Synexis technology is part of Cal-Maine Foods’ broader approach to continuous microbial reduction, sanitation, and operational resilience.”

Continued investment in biosecurity, food safety, and operational resilience is essential to protecting U.S. egg production and supporting a reliable domestic food supply.
