How about a guide that says which foods are the most contaminated and which are least contaminated with respect to the presence of pesticide residues in the market? It should be of great help for the consumers to look for organic versions of most contaminated and buy normal versions in case of least contaminated ones. According to the NGO Environmental Working Group (EWG), a knowledge about the safety of various fruits and vegetables will help the consumer to stretch his money to the maximum extent possible by restricting the buying of costly organic products to those categories known to carry high levels of contaminants.
"It's not always easy to find organic foods and sometimes they cost a bit more. So not all of your food has to be organic. But foods which contain higher amounts of pesticides are the ones you should try to buy organic.Pesticides are hard to wash off completely and they can seep into fruits and veggies. According to the Environmental Working Group (EWG), consumers can reduce their pesticide exposure 80-percent by avoiding the most contaminated fruits and vegetables".
