Wash Your Food and Wash it Right
Wash all your fruits and vegetables. According to the CSE, washing them with 2% of salt water will remove most of the contact pesticide residues that normally appear on the surface of the vegetables and fruits. Almost 75 to 80 percent of pesticide residues are removed by cold water washing. Also, be more thorough with these fruits and vegetables in specific: grapes, apples, guava, plums, mangoes, peaches and pears and vegetables like tomatoes, brinjal and okra as they might carry more residue in their crevices.
Whip up a solution with 10 percent white vinegar and 90 percent water and soak your veggies and fruits in them. Stir them around and rinse thoroughly. Be careful while washing fruits like berries, and those with a thin peel as the solution might damage their porous outer-skin.
Blanch and Peel
Treat your vegetables to warm water for a short while and this should remove any leftover residue. Peeling is another efficient way to remove residue and comes highly recommended especially when there might be some residue in the crevices of the fruit. Also, when cooking with chicken or meat, cut off the excess fat and skin as it could have absorbed unwanted pesticide residue.
