There's more unpleasant stuff in all your food than you realize, and always has been. It's impossible to eliminate grubs from blackberries, no matter how many times you wash them. All you can do is rinse them in salt water so they stop climbing out from the crevices. There are insect parts in every jar of jam, trace amounts of rat droppings in every jar of peanut butter (or entire rats), and if you eat enough fresh fish, you'll quickly discover how often it has worms (fortunately, most fish for sale was frozen at some point, rendering the worms dead and nearly undetectable). Processed or organic, plant or animal, all food is contaminated. Even salt -- ever think about what's in sea salt besides NaCl? Hint: nothing you'd want to eat. And table salt has it too, only less of it.
Fortunately, if you follow proper food-handling practices, none of this is unsafe. But if you think you don't eat a few hundred parts-per-million each day of hidden disgusting things, you're deceiving yourself.
