taking Dairy Processing class in Utah long time ago, the teacher said FDA is very strict on the usage of those pestcide. And he gave an example: a farm used high volume of pestcide on apples, then sold them to a juice maker, the juice maker cleaned those apples until the residue is under the limit, then made apple juice out of it. But after FDA checked that out, they requested the juice maker to destroy all the juices. Coz the apple the juice maker bought has the residue higher than the limit. So u can see how strict that is.
