What are contemporary approaches regarding dealing with bug infestation of dates? Do Kashrut agencies (e.g. the Orthodox Union) regularly inspect crops to determine infestation levels? And if so, what are the statistics used to be lenient (miut she'eino matzuy)? I keep finding insects in Medjool dates (Mehadrin brand from Israel) that I get at Costco: its packaging has an OU but does not indicate a need for checking.
