The problem with Bedikas Toloi'yim hashgochas. Whether you are the certifier of the food service establishment or the certifier of the prechecked vegetables. Most of the Machshirim don't have handle nor suffecient on hands knowledge of the actual bedikas, especially mites & miners.
Yet they set guidelines & accept systems without so much being able to assess the quality of their mashgichim in bedikasToloi'yim, and they don't comprehend what we want from their life. What a shame.
