Cold atmospheric pressure plasma could potentially be used to reduce number of listeria monocytogenes found on pre-packaged, ready-to-eat foods, research shows

LOS ANGELES , January 10, 2012 () – According to research performed by a group of scientists from Denmark, cold atmospheric pressure plasma (CAPP) could potentially be used to reduce the number of listeria monocytogenes found on the surface of pre-packaged, ready-to-eat foods, MeatProcess.com Jan. 3.

The researchers were examining the effectiveness of indirectly applied CAPP on reducing the amount of listeria monocytogenes found on the surface of pre-packaged, ready-to-eat foods.

The samples of food were placed some distance away from the plasma, and exposure was limited to the reactive species formed on on sliced bresola that was inoculated with listeria in sealed polyethylene bags.

The research showed that multiple treatments at 10-minute intervals reduced the amount of listeria found on the samples.
