And all of them, [if] there was terumah in their mouths, R' Eliezer says: They swal-low [it]. But R' Yehoshua says: They should expel [it]. [If] they said to him: “You have become tamei”, or: “The terumah has become tamei,” R' Eliezer says: He swallows [it]. But R' Yehoshua says: He expels [it]. [If they said to him,] “You were tamei”, or “The terumah was tamei,” or it became known that it was tevel, or maaser rishon whose terumah had not been taken, or maaser sheni or consecrated produce that have not been redeemed, or [if] he tasted the taste of a bedbug, he expels it.
