Demonstration of the suppression effect against O157
Operation of one Streamer unit
Operation of two Streamer units
Testing organization
Japan Food Research Laboratories
Test method
By irradiating the O157 with Streamer for 1, 2, 3, 4, 8 hours and inoculating the cultured cells, we observed the residual state of the O157 by the difference in the Streamer irradiation time.
The survival rate of O157 after 2 hours of the Streamer irradiation was 0.1% for operation of two units compared to 1.8% for one unit operation, confirming that the suppression was 18 times more effective. In addition, after 3 hours, it was confirmed that the suppression effect was 99.9% both with the one unit operation as well as with the two unit operation.
* The results are obtained from demonstration of solely the Daikin Streamer discharge device in an experimental condition.
O157 with strong toxin and infectivity
O157 produces a strong toxin called Verotoxin, which causes abdominal pain, hemorrhagic diarrhea, and vomiting. It is one of the most dangerous bacteria that can cause severe symptoms and deaths when infected in infants and the elderly. In addition, infectiousness is strong. General food poisoning only develops when "about 1 million" of bacteria invade, whereas O157 develops food poisoning even with a small number of "about 100" bacteria.
