Detecting Salmonella in Food Samples in Minutes
Added Jul 31, 2015 | Rate View top rated
Salmonella is a food-born pathogen that can cause severe gastrointestinal problems. Purdue University engineers have found a quicker method to detect salmonella in food, which is about three times faster than current detection methods. They developed a machine called BARDOT and it uses laser technology. They first incubate food samples on a plate for about 16 hours and then placed inside BARDOT. In a matter of minutes, the laser scans bacteria colonies and it produces black and white images.
