Suppresses the pathogen E. coli O157, which causes food poisoning

Share This Post

It has been shown that the active ingredient produced by STREAMER technology decomposes and neutralizes O157 by contacting O157, which causes food poisoning. Furthermore, this time, it has been demonstrated that the suppression effect is increased 18 times by operating two Streamer units.

*This is a demonstration result using a STREAMER discharge device for testing. The effect of the product equipped with STREAMER technology or the effect in the actual use environment may differ.

Demonstration of suppression effect on O157

Operation of one STREAMER unit

Operation of two STREAMER units

The survival rate of O157 after 2 h of STREAMER irradiation was 0.1% for two operating units compared with 1.8% for one operating unit, confirming that the suppression effect was 18 times. In addition, after 3 hours, it was confirmed that the suppression effect was 99.9% for one-unit operation and two-unit operation.

Testing Organization

Japan Food Research Laboratories

Testing Method

By irradiating O157 with a STREAMER for 1, 2, 3, 4, 8 h and inoculation of the cultured cells, we observed the state of the O157 residue with different STREAMER irradiation times.

O157 with strong toxin and infectious/spreading power

O157 produces a powerful toxin called Verotoxin, which causes abdominal pain, bloody diarrhea, and vomiting. It is one of the very dangerous bacteria that can cause severe symptoms and death when infected in infants and the elderly. In addition, the infectious power is strong. General food poisoning does not develop unless “about 1 million” bacteria attack, whereas O157 develops food poisoning with even a small number of “about 100” bacteria.
