הָאוֹכֵל כְּזַיִת חֵלֶב בְּמֵזִיד חַיָּב כָּרֵת. בְּשׁוֹגֵג מֵבִיא חַטָּאת קְבוּעָה. וּבְפֵרוּשׁ אָמְרָה תּוֹרָה שֶׁאֵינוֹ חַיָּב אֶלָּא עַל שְׁלֹשָׁה מִינֵי בְּהֵמָה טְהוֹרָה בִּלְבַד שֶׁנֶּאֱמַר (ויקרא ז כג) "כָּל חֵלֶב שׁוֹר וְכֶשֶׂב וָעֵז לֹא תֹאכֵלוּ" בֵּין שֶׁאָכַל מֵחֵלֶב שְׁחוּטָה בֵּין שֶׁאָכַל מֵחֵלֶב נְבֵלָה וּטְרֵפָה שֶׁלָּהֶן. אֲבָל שְׁאָר בְּהֵמָה וְחַיָּה בֵּין טְמֵאָה בֵּין טְהוֹרָה חֶלְבָּהּ כִּבְשָׂרָהּ. וְכֵן נֵפֶל שֶׁל שְׁלֹשָׁה מִינֵי בְּהֵמָה טְהוֹרָה חֶלְבּוֹ כִּבְשָׂרוֹ וְהָאוֹכֵל מֵחֶלְבּוֹ כְּזַיִת לוֹקֶה מִשּׁוּם אוֹכֵל נְבֵלָה:
When a person willfully eats an olive-sized portion of forbidden fat, he is liable for kerat. If he partakes of it inadvertently, he must bring a fixed sin-offering. It is explicitly stated in the Torah that he is liable for partaking [of the fat] of the three species of kosher domesticated animals alone, as [Leviticus 7:23] states: "Do not partake of any fat from an ox, lamb, or goat." [This applies] whether one partakes of fat from an animal that is ritually slaughtered or one partakes of fat from a nevelah or a trefe [from a kosher species]. With regard to other domesticated animals and wild beasts, whether non-kosher or kosher, their fat is comparable to their meat. Similarly, the fat of a stillborn fetus of the three species of kosher animals is comparable to its flesh. When one partakes of an olive-sized portion of it, one is liable for lashes for partaking of a nevelah.
