 Without further ado, here's the list for 2024, starting with the most contaminated. Non-organic strawberries, leafy greens such as spinach and kale, collard and mustard greens, grapes, peaches, pears, nectarines, apples, bell and hot peppers, cherries, blueberries, and green beans. Now, don't get me wrong. You can and should eat these delicious foods. Just make sure to rinse them under running water regularly.
