Reference for Keritot 30:39

<big><strong>גמ׳</strong></big> מאי קשיא ליה לר"ש

Said R'Joshua: I have heard that if one ate, in one spell of unawareness, of a sacrifice from five different dishes, he is guilty of the transgression of the law of sacrilege for each of them; and it seems to me that the case in question may be derived therefrom by an a fortiori conclusion.
