328. Insects in Fruit

46:33 If vinegar becomes infested with insects, it cannot be fixed by filtering. The tiny bugs that may be found in vinegar can pass through the cloth and filtering actually makes the situation worse. This is because the bugs that grow in this environment (the vinegar) do not become forbidden until they are removed from it. Filtering may cause such insects to be separated from the vinegar, rendering them impermissible, but then allow them to slip back in. A better course of action is to boil the vinegar and then to filter it after the insects have died, so they cannot return.

46:34 Insects that grow in fruit that is still connected to the tree are forbidden even though they have not moved from one place to another. They appear like black dots in fruit, beans and lentils. This spot, where the insect starts to grow, must be dug out thoroughly because it is as just as forbidden as the actual bug.
