הלכה על מכות 28:8

From the laws of the commandment is, for example, that which they, may their memory be blessed, said (Makkot 14b) that it is forbidden to render [sacrifices] impure or to bring about their impurity. But one who makes them impure is not lashed. Rather it is the pure one who eats them that are impure that is lashed – from that which is written (Leviticus 7:19), "it shall not be eaten." And even though this verse was about the inauguration, the law is the same for all of the other sacrifices. And even one who eats a kazayit of frankincense from the meal-offering which became impure after it was sanctified in a vessel is lashed; as it too is a part of the sacrifice. And the liability only comes with becoming impure [from] a primary source of impurity or its derivative by Torah writ. But on account of rabbinic impurity, he is not lashed [by Torah writ], but we do administer rabbinic lashes of rebellion upon him. And the rest of its details are in the thirteenth chapter of Zevachim.
