Food safety firm ZEGO is using blockchain to test products for residue of a deadly chemical tied to a recent $289 million Monsanto lawsuit, according to a press release published August 16.

Earlier this month, Monsanto was fined $289 million in damages after a court ruled in favor of a plaintiff’s claims that the company’s use of a herbicide containing glyphosate had caused his cancer.

ZEGO reportedly has a patent-pending blockchain system that would allow companies to test foodstuffs for glyphosate. The company says it had initially developed the solution to enable consumers to make better informed choices about the presence of allergens and gluten in various goods.

According to ZEGO, glyphosate testing can further be used as a means of verifying suppliers’ purported organic and non-GMO certifications, which it implies can often be fraudulent.
