My brother in law works as a biologist for a large processed food company and he has to measure and track all the different batches of food they process. According to him it’s the exact opposite, there are measurable amounts of pesticide in all of the non-organic foods they get in (apples, sweet potatoes, etc) and absolutely zero measurable amount of pesticides in the organic food they receive.

I used to think the same as you until hearing it from him that it’s an actual measurable difference and the exact opposite of what I thought.
