New Device Could Make It Easier To Identify Food Pathogens

By Indiana Public Media News Staff

Posted February 29, 2016

Scientists at Purdue have developed a microwave-sized tool that can detect pathogens by scanning petri dishes with lasers. Scientists say the technology is significantly faster than traditional methods, such as staining, at identifying harmful microbes.

The device is called BARDOT -- short for Bacteria Rapid Detection Using Optical Scattering Technology.

Arun Bhunia, a Purdue food science professor who helped develop the tool, says when spread on a petri dish, microbes such as salmonella create distinctive patterns of growth. The laser can identify different patterns and match them to bacteria.

"Each organism based on their physiological properties or genus of species form a different type of colony scatter-signature, and essentially that gives us a different way to identify each of those organisms."

Bhunia says BARDOT means testing for bacteria in food could take hours, not days.

"Government-level laboratories can definitely use this for outbreak investigations. Food testing laboratories would could be other potential customer who can test their food products before they're sold for human consumption."

Indiana State Department of Health Lab Director Judy Lovchik agrees BARDOT would cut down on identification time, but says for now, the government can't use it.

"Even if we wanted to, we could not at this time use the BARDOT no matter how wonderful we thought it was because regulatory testing is regulated."

Lovchik says the biggest problem her department sees is in the pre-analysis stage, when bacteria can be compromised as it's transported to a lab. The technology has been licensed to a German biotech firm.
