The pesticide levels found on the produce described in some articles are often 10 to 100 times lower than the approved level. There is no real risk. Even if one apple got through the system with a marginally higher level, there's no danger. I can tell you what is toxic about apples, and that is eating the seeds. Hold on, lima beans, cherries, apricots and peaches also contain low levels of cyanide.
Many common plants contain natural poisons.
And there are other risks for young kids. I would speculate that more may have died accidentally choking on grapes and peanuts that ever get sick from eating pesticide-treated vegetables or fruits. It is the identical hormone that cows produce and this is the natural way to promote increased milk production. The old way was to add drugs such as antibiotics to the cows' feed. But these are synthetic chemicals not normally found in cows.
