Mishnah Pesachim
These are the things with which they fulfill their obligation on Pesah: with wheat, with barley, with spelt, with rye, and with oats. And they fulfill [the obligation] with demai, with first tithe whose terumah has been separated, and with second tithe or sanctified property which have been redeemed; And priests [can fulfill their obligation] with hallah and terumah. But not with untithed produce, nor with first tithe whose terumah has not been separated, nor with second tithe or sanctified property which have not been redeemed. Loaves of the thanksgiving offering and the wafers of a nazirite: If he made them for himself, they cannot fulfill [their obligation] with them; If he made them to sell in the market, they can fulfill [their obligation] with them.

How much untithed produce is one to eat to become liable? Rabbi Shimon says: “Any amount.” The Sages say: “An olive's size.” Rabbi Shimon said to them: “Do you not admit that if one ate the minutest ant that he would be liable? They said to him: “[Only] because it is a whole creature.” He said to them: “Even a grain of wheat is a whole entity.”
