Thoughts on Kashruth Certification Policies
By Michael Makovi
In my naivete, I have only recently become aware that the Israeli Rabbanut offers hashgahat kashrut (kosher certification) only for those establishments which are closed on Shabbat. Any establishment which is open for Shabbat will be denied supervision, no matter how kosher their food may in fact be.
This policy is based on the halakha that one may not benefit from forbidden labor that was performed on Shabbat. Therefore, the Rabbanut denies kosher supervision to establishments open on Shabbat, since any food cooked on Shabbat is forbidden according to hilkhot shabbat (although not hilkhot kashrut). Additionally, a hekhsher, if present, is assumed to condone the Shabbat violation.
