Orach Chaim 442:2-5 Mouldy Bread and Starched Laundry

Hapas Atzmo, bread itself She'ipsho, which became moldy.

V'Nifse LeMelech HaKelev HaKelev.

and it became so moldy that even a dog wouldn't eat it.

Which is some sort of medicinal plaster, which Mishra was going to explain what it is, that has become putrid.

You are not obligated to destroy and to get rid of that Chometz.

so bread itself which became moldy all of this applies you don't have to get rid of Chometz which became moldy so long as that happened before the Zman Issa i.e. Erev Pesach Because if it was good bread at the time of when Isaac Hometz kicked in, and then later it became moldy, even though it's now moldy, it's so moldy that a kelev wouldn't eat it, nevertheless, there is a Because at the end of the day, there was a chiv to get rid of it at the moment before it became moldy, at the moment of biur.

And therefore, if it later became moldy, that's not good enough.

So we're talking about a situation where the chometz became moldy before the Zman Issa.

Now, how bad does it have to get? says the Mishnah Brewer, then there's no chiv biur on chometz, which became moldy.

so boldy, so putrid, that a dog would eat it.

It's considered the dust of the earth.

However, if it didn't become so bad that a dog would eat it, even though a human being would eat it, it's not appropriate for him to eat.

However, Still, at the end of the day, since a dog could eat it, then you've got a chi of beer, like any other Chometz gomer.

Because it could make other loaves into Chometz.

Okay, umelugma.

Now, what has this got to do with Chometz? You've got some sort of bandage, and you apply...

flour and figs and other things on it, that he chews and he puts it onto his wound.

So it's clearly made of some kemach, and therefore you've got a problem.

But it became soiled, it became putrid.

Again, it's got to get so bad that a dog wouldn't eat it.

Like with the bread we mentioned before.

If, however, it became Chometz, And then it became putrid.

Again, it's only, you're only allowed to keep it if it became in that state, in that nisracha state before Pesach.

We said before regarding bread.

If, however, it became putrid before it became into Chomet, then no problem.
