When a Carcass Ceases to Be a Carcass

How the Talmud derives the decay threshold for ritual carcass impurity from the Torah's permission to feed it to a resident stranger.

לֹ֣א תֹאכְל֣וּ כׇל־נְ֠בֵלָ֠ה לַגֵּ֨ר אֲשֶׁר־בִּשְׁעָרֶ֜יךָ תִּתְּנֶ֣נָּה וַאֲכָלָ֗הּ א֤וֹ מָכֹר֙ לְנׇכְרִ֔י כִּ֣י עַ֤ם קָדוֹשׁ֙ אַתָּ֔ה לַיהֹוָ֖ה אֱלֹהֶ֑יךָ לֹֽא־תְבַשֵּׁ֥ל גְּדִ֖י בַּחֲלֵ֥ב אִמּֽוֹ׃ {פ}

You shall not eat anything that has died a natural death; give it to the stranger in your community to eat, or you may sell it to a foreigner. For you are a people consecrated to the ETERNAL your God. You shall not boil a kid in its mother’s milk. (Deuteronomy 14:21)

The Verse in Its Plain Meaning

In Parashat Re'eh, the Torah instructs the Jewish people concerning dietary purity and holiness. The verse commands: "You shall not eat anything that has died a natural death; give it to the stranger in your community to eat, or you may sell it to a foreigner".

In its plain sense, the verse establishes an absolute ban against consuming an animal that died without valid ritual slaughter (נבלה, nevelah). Sforno notes that this prohibition applies even to an animal of a kosher species. Instead of eating the carcass, an Israelite may give it as food to a resident stranger (גר תושב, ger toshav), who, as Rashi explains, has renounced idolatry but is permitted to eat nonslaughtered meat.

לֹ֣א תֹאכְל֣וּ כׇל־נְ֠בֵלָ֠ה לַגֵּ֨ר אֲשֶׁר־בִּשְׁעָרֶ֜יךָ תִּתְּנֶ֣נָּה וַאֲכָלָ֗הּ

You shall not eat anything that has died a natural death; give it to the stranger in your community to eat. (Deuteronomy 14:21)

The Gemara's Dilemma on Decayed Impurity

In Bekhorot, the Gemara investigates the mechanics of nullification and whether a carcass retains its ritual impurity when it spoils. The discussion arises when an animal discharges an ambiguous congealed mass of blood (חררת דם). The Sages teach that this discharge imparts no ritual defilement through contact or carrying.

The Gemara suggests that this discharge is ritually inert because it constitutes decayed impurity (טומאה סרוחה). An animal product that decomposes completely forfeits its status as a carcass. This inquiry leads the Gemara to investigate the precise legal standard: at what stage of deterioration does a carcass cease to defile?

דִּלְמָא, וַדַּאי שָׁאנֵי הָכָא, דְּהָוְיָא לַהּ טוּמְאָה סְרוּחָה.

Perhaps it is certainly different here, as it is decayed impurity. (Bekhorot 23a:8)

The Derashah of Bar Padda

To resolve this definition, Bar Padda turns to the phrasing of the prohibition in Deuteronomy 14:21. He establishes a distinction between severe impurity (טוּמְאָה חֲמוּרָה), such as a carcass that defiles people and vessels through contact and carrying, and light impurity (טוּמְאָה קַלָּה), which affects only food.

Bar Padda anchors the definition of a carcass directly to the clause permitting it to a stranger. By juxtaposing the prohibition with the gift to the ger toshav, the verse links the very definition of the object to human consumption. Only meat that remains fit for consumption by a stranger is legally considered a carcass. Once it putrefies beyond human edibility, severe defilement ceases.

הָרְאוּיָה לַגֵּר קְרוּיָה ״נְבֵילָה״, וְשֶׁאֵינָהּ רְאוּיָה לַגֵּר אֵינָהּ קְרוּיָה ״נְבֵילָה״.

That which is fit for a stranger is called a carcass, and that which is not fit for a stranger is not called a carcass. (Bekhorot 23b:2)

The Debate Between Sages

Rabbi Yochanan disputes Bar Padda's measure and asserts that even severe impurity persists as long as the meat is edible to a dog. Rabbi Yochanan interprets Deuteronomy 14:21 differently, arguing that the verse excludes only an animal that was decomposed from the very start, such as an animal whose flesh rotted while it was still alive.

Bar Padda counters that an animal rotted from the outset is mere dust and requires no scriptural exclusion. Through Bar Padda's reading of the verse, the Torah sets the culinary standard of the non-Jewish resident as the legal threshold for severe carcass impurity.

A dead animal ceases to transmit severe carcass impurity once it spoils beyond what a resident stranger would eat.
