הָאוֹכֵל כְּזַיִת מִן הַדָּם בְּמֵזִיד חַיָּב כָּרֵת בְּשׁוֹגֵג מֵבִיא חַטָּאת קְבוּעָה. וְדָבָר מְפֹרָשׁ בַּתּוֹרָה שֶׁאֵינוֹ חַיָּב אֶלָּא עַל דַּם בְּהֵמָה חַיָּה וְעוֹף בִּלְבַד בֵּין טְמֵאִין בֵּין טְהוֹרִין שֶׁנֶּאֱמַר (ויקרא ז כו) "וְכָל דָּם לֹא תֹאכְלוּ בְּכל מוֹשְׁבֹתֵיכֶם לָעוֹף וְלַבְּהֵמָה". וְחַיָּה בִּכְלַל בְּהֵמָה שֶׁנֶּאֱמַר (דברים יד ד) "זֹאת הַבְּהֵמָה אֲשֶׁר תֹּאכֵלוּ שׁוֹר" וְגוֹ' (דברים יד ה) "אַיָּל וּצְבִי" וְגוֹ'. אֲבָל דַּם דָּגִים וַחֲגָבִים וּשְׁקָצִים וּרְמָשִׂים וְדַם הָאָדָם אֵין חַיָּבִין עָלָיו מִשּׁוּם דָּם. לְפִיכָךְ דַּם דָּגִים וַחֲגָבִים טְהוֹרִים מֻתָּר לְאָכְלוֹ וַאֲפִלּוּ כְּנָסוֹ בִּכְלִי וְשָׁתָהוּ מֻתָּר. וְדַם חֲגָבִים וְדָגִים טְמֵאִים אָסוּר מִשּׁוּם שֶׁהוּא תַּמְצִית גּוּפָן כַּחֲלֵב בְּהֵמָה טְמֵאָה. וְדַם שְׁקָצִים כִּבְשָׂרָן כְּמוֹ שֶׁבֵּאַרְנוּ:
When a person partakes of an olive-sized portion of blood intentionally, he is liable for karet. If he does so inadvertently, he is liable to bring a fixed sin-offering. It is explicitly stated in the Torah that he is liable for partaking of blood from all domesticated animals, wild beasts, and fowl alone. This applies whether they are from a non-kosher or kosher species, as [Leviticus 7:26] states: "You may not partake of any blood from a fowl or an animal in all your dwellings." A wild beast is considered as an animal as [Deuteronomy 14:4-5] states: "These are the animals that you may eat: an ox... a gazelle and a deer...." One is not, [by contrast,] liable for transgressing of the prohibition against partaking of blood for partaking of the blood of fish, locusts, creeping animals, teeming animals, or humans. Therefore it is permitted to partake of the blood of kosher fish and locusts. Even if one collects it in a container and drinks it, it is permitted. The blood of non-kosher fish and locusts is forbidden because it comes from their bodies like the milk of a non-kosher animal. The blood of creeping animals is comparable to their bodies, as we explained.
