Kansas State University researchers have developed a molecular test for detecting E. coli in cattle by identifying genes specific to the bacteria.

The laboratory test targets four genes in pathogenic Shiga toxin-producing E. coli O157:H7 found in cattle feces.

The test is rapid and less labor-intensive than current detection methods, according to the university. The method also can be automated and test many samples in a short period of time.

"Developing a method to detect E. coli before it can potentially contaminate the food supply benefits the beef industry by preventing costly recalls but also benefits the consumer by ensuring the safety of the beef supply," said Lance Noll, master's student in veterinary biomedical science. Noll is part of a team in the College of Veterinary Medicine studying pre-harvest food safety in beef cattle.

A USDA Coordinated Agriculture Project grant is funding the work.
