Many frum stores including Lakewood, catskills, etc stores are selling all different fruits and vegetables that are infested and a bedikah by an expert is required. Some can't be checked e.g. strawberries must be peeled, Corn on the cob-Kernels must be removed prior to using & washed.
Scallions-must be cut open all of the tubers lenghtwise & rinsed well. Frozen spinach, brocolli with florets, cauliflower should not be used at all.
The Dole with or without the stickers, should not be used. Frozen strawberries with hashgocha must be pureed prior to using.
