I spilled these blueberries yesterday morning all over the supermarket floor while I was grocery shopping. I bought them and brought them home anyhow (I hate waste), and disinfected them by soaking them first in vinegar (straight, not diluted) and then in 3% hydrogen peroxide. This food disinfection technique is supposed to be as good as chlorine bleach.
Shortly after this photo was taken I ate the blueberries, and have suffered no ill effects – so I guess I could say it works. Ish.
