Interesting article on how some food borne pathogens can live, even when attacked with typical, proven disinfectants......

That's why I wipe my cutting boards with straight vodka. Nothing can multiply if you get it drunk enough! Ask any traffic cop.

I am disappointed that they did not also test the use of germicidal UV light which is totally non-toxic.

From what I have read on "UV" ... It penetrates very little ... close to zero... dust on the source, reduces it's effectiveness.... Maybe they did test it and found it to have no effectiveness on "embedded or encapsulated" bacteria... th_dunno-1[1].gif

I am interested to know because I use a 55 watt germicidal light to disinfect the kitchen area.

 

UV does have some degree of penetrating power, that's why you can get some sun burn with clothing on. I would assume whatever film the germs develop would be ultra thin.

The sunburn you get is from a shorter longer wave length UV.... Not the same as germicidal..... And cloth is not a 100% blocker... it is a weave..... Dave


FDA calls UV-C at 200-280 nanometers the “germicidal range” because it “effectively inactivates bacteria and viruses.” FDA explains that the “germicidal properties of UV irradiation are mainly due to DNA mutations induced through absorption of UV light by DNA molecules.”

I thought it was a very good article also...... Amazing how folks can interpret UV Radiation as NUCLEAR RADIATION.... some things I just don't understand..... maybe they don't read this stuff..... OR it isn't explained very well.... th_dunno-1[1].gif
