If an oven was stoked with orlah shells, and he baked bread in it, the bread must be burned. [If] it became mixed up with others, it is nullified in two hundred and one.

[If] someone has bundles of fenugreek of kilei hakerem, they must be burned. [If] they were mixed up with others, they all must be burned, [these are] the words of R' Meir. But the Sages say: They are nullified in two hundred and one.

For R' Meir says: That which is customarily counted dooms [a mixture] to burning. But the Sages say: Nothing dooms [a mixture] to burning excepting only six things. And R' Akiva says: Seven. And these are they: walnuts of Perech, pomegranates of Badan, and sealed barrels, and regenerations of beets, and stems of cabbage, and Greek gourd. R' Akiva says: Also loaves of a householder. That which is subject to orlah [is forbidden as] orlah. [That which is subject] to kilei hakerem [is forbidden as] kilei hakerem.

How so? [If] the walnuts became smashed, the pomegranates became split, the barrels became opened, the gourds became sliced, [or] the loaves became sliced, they are nullified in two hundred and one.
