Mishnah 3ג׳

טִפַּת חָלָב שֶׁנָּפְלָה עַל הַחֲתִיכָה, אִם יֶשׁ בָּהּ בְּנוֹתֵן טַעַם בְּאוֹתָהּ חֲתִיכָה, אָסוּר. נִעֵר אֶת הַקְּדֵרָה, אִם יֶשׁ בָּהּ בְּנוֹתֵן טַעַם בְּאוֹתָהּ קְדֵרָה, אָסוּר. הַכְּחָל, קוֹרְעוֹ וּמוֹצִיא אֶת חֲלָבוֹ. לֹא קְרָעוֹ, אֵינוֹ עוֹבֵר עָלָיו. הַלֵּב, קוֹרְעוֹ וּמוֹצִיא אֶת דָּמוֹ. לֹא קְרָעוֹ, אֵינוֹ עוֹבֵר עָלָיו. הַמַּעֲלֶה אֶת הָעוֹף עִם הַגְּבִינָה עַל הַשֻּׁלְחָן, אֵינוֹ עוֹבֵר בְּלֹא תַעֲשֶׂה:

A drop of milk which fell on a piece [of meat], if there is enough of it to give flavor into that piece, it is forbidden. [If] one stirred the pot, if there is enough of it to give flavor to the [contents] of that pot, it is forbidden. The udder: one tears it open and removes its milk. [If] one did not tear it, one does not transgress through it. The heart: one tears it and removes its blood. [If] one did not tear it, one does not transgress through it. One who places a bird with cheese on the table does not transgress on a negative precept.

Mishnah 4ד׳

בְּשַׂר בְּהֵמָה טְהוֹרָה בַּחֲלֵב בְּהֵמָה טְהוֹרָה, אָסוּר לְבַשֵּׁל וְאָסוּר בַּהֲנָאָה. בְּשַׂר בְּהֵמָה טְהוֹרָה בַּחֲלֵב בְּהֵמָה טְמֵאָה, בְּשַׂר בְּהֵמָה טְמֵאָה בַּחֲלֵב בְּהֵמָה טְהוֹרָה, מֻתָּר לְבַשֵּׁל וּמֻתָּר בַּהֲנָאָה. רַבִּי עֲקִיבָא אוֹמֵר, חַיָּה וָעוֹף אֵינָם מִן הַתּוֹרָה, שֶׁנֶּאֱמַר, לֹא תְבַשֵּׁל גְּדִי בַּחֲלֵב אִמּוֹ, שָׁלשׁ פְּעָמִים, פְּרָט לְחַיָּה וּלְעוֹף וְלִבְהֵמָה טְמֵאָה. רַבִּי יוֹסֵי הַגְּלִילִי אוֹמֵר, נֶאֱמַר (דברים יד), לֹא תֹאכְלוּ כָל נְבֵלָה, וְנֶאֱמַר (שם), לֹא תְבַשֵּׁל גְּדִי בַּחֲלֵב אִמּוֹ. אֶת שֶׁאָסוּר מִשּׁוּם נְבֵלָה, אָסוּר לְבַשֵּׁל בְּחָלָב. עוֹף, שֶׁאָסוּר מִשּׁוּם נְבֵלָה, יָכוֹל יְהֵא אָסוּר לְבַשֵּׁל בְּחָלָב, תַּלְמוּד לוֹמַר בַּחֲלֵב אִמּוֹ, יָצָא עוֹף, שֶׁאֵין לוֹ חֲלֵב אֵם:

[A mixture of] the meat of a permitted animal with the milk of a permitted animal is forbidden to cook and forbidden from benefit. [A mixture of] the meat of a permitted animal with the milk of a prohibited animal, [or] [a mixture] of the meat of a prohibited animal with the milk of a permitted animal is permissible to cook and permissible for benefit. Rabbi Akiva says, "Wild animals and birds are not [forbidden in mixtures with milk] from the Torah, as it says, 'You may not cook a kid in its mother's milk,' three times. It exempts the wild animal, the bird, and the prohibited domesticated animal." Rabbi Yose HaGelili says, "It is stated, 'You may not eat any nevelah [an improperly slaughtered animal of a permitted species],' (Deuteronomy 14:21) and it is stated, 'You may not cook a kid in its mother's milk,' (Ibid.). That which [may become] forbidden as nevelah is forbidden to cook with milk. A bird, which [may become] forbidden as a nevelah, one might think that it should be forbidden to cook with milk, [but] the Torah says, "In its mother's milk." This excludes a bird, which does not have mother's milk.
