Researchers develop new method to detect E. coli

Research: News Roundup from the March 2020 issue of Canadian Cattlemen

Kansas State University researchers have cut the time required to detect Shiga toxin-producing E. coli, or STEC, in ground beef.

“While the current, commonly used testing method is considered to be the gold standard, it is tedious and requires many days to obtain results that adequately differentiate the bacteria,” said Gary Anderson, director of the International Animal Health and Food Safety Institute at the K-State Olathe campus, in a media release.

The new method requires only a day to confirm results. It was developed for research and food safety inspections that require shorter turnaround and high throughput, without sacrificing detection accuracy. It uses a Kansas State University-patented method with the partition-based multichannel digital polymerase chain reaction system.
