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

A new device designed to sample and detect foodborne bacteria is being trialled by scientists at the University of Southampton. The Biolisme project is using research from the University to develop a sensor capable of collecting and detecting Listeria monocytogenes on food industry surfaces, thereby preventing contaminated products from entering the market.

Listeria monocytogenes is a pathogen that causes listeriosis, an infection with symptoms of fever, vomiting and diarrhoea, that can spread to other parts of the body and lead to more serious complications, like meningitis.

Transmitted by ready-to-eat foods, such as milk, cheese, vegetables, raw and smoked fish, meat and cold cuts, Listeria monocytogenes has the highest hospitalisation (92 per cent) and death (18 per cent) rate among all foodborne pathogens. Listeriosis mainly affects pregnant women, new-born children, the elderly and people with weakened immune systems.

Current techniques to detect the bacteria take days of testing in labs, but the new device aims to collect and detect the pathogen on location within three to four hours. This early and rapid detection can avoid the cross contamination of ready-to-eat food products.

Traditional methods of testing, where sample cells are cultivated in labs, are also flawed. 'Stressed' cells will not grow in cultures (and will therefore produce negative results) despite the bacteria being present, live and potentially harmful.

Alternative techniques, based on molecular methods, will detect all cell types, but don't differentiate between live and harmless dead cells, which can remain after disinfection.

The new device is designed to sample single cells and biofilms - groups of microorganisms where cells stick together on surfaces. Compressed air and water is used to remove the cells before they are introduced to an antibody. If Listeria monocytogenes is present, cells react with the antibody to produce
