Norovirus animation: How cold plasma can kill virus that causes food poisoning
  • 9 years ago
Scientists have found cold plasma effective in eliminating norovirus, a virus that causes food poisoning.

Norovirus started to gain international attention after a number of cases where hundreds of cruise ship passengers became infected, according to the BBC. The most common symptoms include vomiting and diarrhea.

Norovirus has displayed strong resistance to different chemical disinfectants. Bleach, a chlorine-based solution, is known to be the most effective disinfectant against norovirus.

A team of German scientists studied the effectiveness of cold plasma in eliminating norovirus. A cold plasma generator can produce highly noxious ions by creating an electric field to air. Researchers also found that the generator could drive down the number of norovirus particles by 20 to 50 times.

A cold plasma generator, a waterless technology, renders disinfectants unnecessary and can be used in various ways, including to clean hands or cutlery.

Researchers believe a combination of cold plasma and bleach is the most effective way to fend off norovirus.
