New sensor to detect harmful bacteria on food industry surfaces
Date:6/12/2014

a florescent signal, which is detected by a special camera.

Doctor Salom Gio and Professor Bill Keevil from Southampton's Centre for Biological Science Unit have been studying Listeria monocytogenes biofilms under different conditions and will be testing the new prototype. "We researched biofilms under different stresses to find the optimum pressure to remove cells from different surfaces, without disrupting the cells themselves," says Dr Gio. "We also found that biofilms can form on surfaces even if they are covered in tap water.

"The scientific research we have carried out at the University of Southampton has been used by our Biolisme project partners to develop a device which will have major implications for the food industry. By making the process simpler we hope that testing will be conducted more frequently, thereby reducing the chance of infected food having to be recalled or making its way to the consumer."

The prototype sensor has been finalised in France and field trials are now underway to test the device before it is demonstrated in food factories.

Jos Belenguer Ballester, from project partner ainia centro tecnolgico, added: "Biolisme has raised the expectations of food business operators because the devices being developed will allow rapid assessment of the cleanliness of manufacturing plants."
