Biosensor Chip Detects Listeria Bacteria in Food Sample in Two Minutes
Added May 27, 2015 | Rate View top rated
Listeria is one of the most common food-borne pathogens in the world and the third-leading cause of death from food poisoning in the U.S. Currently, detecting listeria bacteria contamination of food requires trained technicians and processes that take several days to complete. For food processing companies that produce and ship large quantities of foodstuff daily, listeria contamination sources can be a moving target that is often missed by current technology. Dr. Carmen Gomes, a research engineer at Texas A&M University, says she has developed a biosensor chip that can detect listeria bacteria in a food sample in two to three minutes. The same technology can be developed to detect other pathogens such as E. coli. Listeria was chosen as the first target pathogen because it can survive even at freezing temperatures.
