Raw vegan problems

Hi guys, just writing to say how important organic veggies are. Now that I've become a vegetarian 6 months ago for health reasons, I've noticed how important it is to thoroughly wash all veggies, especially leafy greens. Once I did not wash a big bunch of spinach and I felt a real acrid taste in my throats and then had a massive vomit 5 mins later. The kids were quite impressed at the green fountain coming from their poor, old dad!
