I have been washing my raw veggies in a sink full of water with 2 to 3 tablespoons of 5% food grade hydogen peroxide to rid them of any nasties for many years. I make the 5% solution from 35% food grade hydrogen peroxide. I have been reading about the E. coli scare on raw packaged spinach and wondered about the effectiveness of my washing method. I also soak sprouting seeds with some 5% food grade hydrogen peroxide and mist the sprouts daily with a 5% solution. I was under the impression from all I have read about food grade hydrogen peroxide that this kills E. coli, etc. Does anyone else know about this? Thanks for any input/advice!
