UPDATE: Calif. delight W/ Hisachdus?
Rav Ekstein removed hashgocha.
Corn on the cob, is known to be infested, including the frozen ones.
Even if it's soaked and salted.
Are the ones from Mexico, Thailand, any better? [No]
Does a Heimish Hashgocha help to elminate, not just minimize the insects? NO
Bottom line, (frsh & frozen, cooked) Remove the kernels & rinse.
NOT THE BABY CORN
