It is true that pesticides can enter the fruit through the skin
, but virtually all studies agree that this is usually only a small amount. The problem really lies mainly with the skin. There are more than 1,000 pesticides on the market, each of which works differently. We can’t lump all pesticides together. In the past, we did have neonicotinoids, which are known to spread throughout the entire plant (and to be lethal to bees), but their use has been strictly restricted in the EU. With virtually all of them, it seems that the problems are mainly limited to the skin. Incidentally, the thicker the skin, the better.
