Mishneh Torah — Forbidden Foods (Ma'akhalot Asurot) הלכות מאכלות אסורות, Chapter 2

מִכְּלָל שֶׁנֶּאֱמַר (דברים יד ו) "וְכָל בְּהֵמָה מַפְרֶסֶת פַּרְסָה וְשֹׁסַעַת שֶׁסַע שְׁתֵּי פְרָסוֹת מַעֲלַת גֵּרָה" שׁוֹמֵעַ אֲנִי שֶׁכָּל שֶׁאֵינָהּ מַעֲלַת גֵּרָה וּמַפְרֶסֶת פַּרְסָה אֲסוּרָה. וְלָאו הַבָּא מִכְּלַל עֲשֵׂה עֲשֵׂה הוּא. וּבְגָמָל וּבַחֲזִיר וּבְאַרְנֶבֶת וּבְשָׁפָן נֶאֱמַר (ויקרא יא ד) (דברים יד ז) "אֶת זֶה לֹא תֹאכְלוּ מִמַּעֲלֵי הַגֵּרָה וּמִמַּפְרִיסֵי הַפַּרְסָה" וְגוֹ' הֲרֵי לָמַדְתָּ שֶׁהֵן בְּלֹא תַּעֲשֶׂה וְאַף עַל פִּי שֶׁיֵּשׁ בָּהֶן סִימָן אֶחָד. וְכָל שֶׁכֵּן שְׁאָר בְּהֵמָה טְמֵאָה וְחַיָּה טְמֵאָה שֶׁאֵין בָּהּ סִימָן כְּלָל שֶׁאִסּוּר אֲכִילָתָם בְּלֹא תַּעֲשֶׂה יֶתֶר עַל עֲשֵׂה הַבָּא מִכְּלַל אוֹתָהּ תֹּאכְלוּ:

Since it is written [Deuteronomy 14:6]: "Any animal that has split hooves, [whose foot] is divided into two hoofs and chews the cud, [this may you eat]," one may derive that any animal that does not chew its cud and have split hoofs is forbidden. A negative commandment that comes as a result of a positive commandment is considered as a positive commandment. (General Principle 6) where the Rambam elaborates in the explanation of the concept of a prohibition derived from a positive commandment. See also Chapter 1, Halachah 1, and notes which deals with this issue.With regard to the camel, the pig, the rabbit, and the hare, [Leviticus 11:4] states: "These you may not eat from those which chew the cud and have split hoofs." From this, you see that they are forbidden by a negative commandment, even though they possess one sign of kashrut. Certainly, this applies to other non-kosher domesticated animals and wild beasts that do not have any signs of kashrut. 24a, et al): "We do not issue a warning on the basis of logical deduction." Implied is that a person is not given lashes when a prohibition is not explicitly mentioned in the Torah, but instead derived through logic. Why then, these commentaries ask, are lashes given for partaking of non-kosher species other than the four mentioned specifically by the Torah?The Rambam offers a resolution to this question in his Sefer HaMitzvot (negative commandment 172). There he explains that in this instance, we are not deriving the prohibition on the basis of logic, for it is already stated in the positive commandment. We are using logic only to derive that this prohibition is also included in the negative commandment. The prohibition against eating them involves a negative commandment in addition to the positive commandment that is derived from "This may you eat."

לְפִיכָךְ כָּל הָאוֹכֵל מִבְּשַׂר בְּהֵמָה וְחַיָּה טְמֵאָה כְּזַיִת לוֹקֶה מִן הַתּוֹרָה. בֵּין שֶׁאָכַל מִן הַבָּשָׂר בֵּין שֶׁאָכַל מִן הַחֵלֶב. לֹא חִלֵּק הַכָּתוּב בִּטְמֵאִים בֵּין בְּשָׂרָם לְחֶלְבָּם:

Therefore anyone who eats an olive sized portion of the meat of a non-kosher domesticated animal or wild beasts is liable for lashes according to Scriptural Law. This applies whether he partook of the meat or the fat. For the Torah did not distinguish between the meat and fat of non-kosher animals.

הָאָדָם אַף עַל פִּי שֶׁנֶּאֱמַר בּוֹ (בראשית ב ז) "וַיְהִי הָאָדָם לְנֶפֶשׁ חַיָּה" אֵינוֹ מִכְּלַל מִינֵי חַיָּה בַּעֲלַת פַּרְסָה לְפִיכָךְ אֵינוֹ בְּלֹא תַּעֲשֶׂה. וְהָאוֹכֵל מִבְּשַׂר הָאָדָם אוֹ מֵחֶלְבּוֹ בֵּין מִן הַחַי בֵּין מִן הַמֵּת אֵינוֹ לוֹקֶה. אֲבָל אָסוּר הוּא בַּעֲשֵׂה שֶׁהֲרֵי מָנָה הַכָּתוּב שִׁבְעַת מִינֵי חַיָּה וְאָמַר בָּהֶן (ויקרא יא ב) "זֹאת הַחַיָּה אֲשֶׁר תֹּאכְלוּ" הָא כָּל שֶׁהוּא חוּץ מֵהֶן לֹא תֹּאכְלוּ וְלָאו הַבָּא מִכְּלַל עֲשֵׂה עֲשֵׂה:

With regard to humans: Although [Genesis 2:7] states: "And the man became a beast with a soul," he is not included in the category of hoofed animals. Therefore, he is not included in the [above] prohibition. Accordingly, one who partakes of meat or fat from a man - whether alive or deceased - is not liable for lashes. It is, however, forbidden [to partake of human meat] because of the positive commandment [mentioned above]. 79:1) follows the Rambam's ruling.The Maggid Mishneh explains the Rambam's position, noting that - as stated in Chapter 3, Halachah 2, and in Chapter 6, Halachot 1-2 - there is no Scriptural prohibition against partaking of milk and blood from a human. Now these leniencies are derived from the exegesis of verses from the Torah. Were the meat of a human not to be forbidden, why would it be necessary to teach that his milk and blood are permitted? Who would have thought otherwise? For the Torah [Leviticus 11:2] lists the seven species of kosher wild beasts and says: "These are the beasts of which you may partake." Implied is that any other than they may not be eaten. And a negative commandment that comes as a result of a positive commandment is considered as a positive commandment.

הָאוֹכֵל כְּזַיִת מִבְּשַׂר עוֹף טָמֵא לוֹקֶה מִן הַתּוֹרָה שֶׁנֶּאֱמַר (ויקרא יא יג) "וְאֶת אֵלֶּה תְּשַׁקְּצוּ מִן הָעוֹף לֹא יֵאָכְלוּ". וַהֲרֵי עָבַר עַל עֲשֵׂה שֶׁנֶּאֱמַר (דברים יד יא) "כָּל צִפּוֹר טְהֹרָה תֹּאכֵלוּ" הָא טְמֵאָה לֹא תֹּאכְלוּ. וְכֵן הָאוֹכֵל כְּזַיִת מִדָּג טָמֵא לוֹקֶה שֶׁנֶּאֱמַר (ויקרא יא יא) "וְשֶׁקֶץ יִהְיוּ לָכֶם" (ויקרא יא יא) "מִבְּשָׂרָם לֹא תֹאכֵלוּ". וְעָבַר עַל עֲשֵׂה שֶׁנֶּאֱמַר (דברים יד ט) "כּל אֲשֶׁר לוֹ סְנַפִּיר וְקַשְׂקֶשֶׂת תֹּאכֵלוּ" מִכְּלַל שֶׁמִּי שֶׁאֵין לוֹ סְנַפִּיר וְקַשְׂקֶשֶׂת לֹא יֵאָכֵל. הָא לָמַדְתָּ שֶׁכָּל הָאוֹכֵל דָּג טָמֵא אוֹ בְּהֵמָה וְחַיָּה טְמֵאָה אוֹ עוֹף טָמֵא בִּטֵּל מִצְוַת עֲשֵׂה וְעָבַר עַל לֹא תַּעֲשֶׂה:

When one partakes of an olive-sized portion of a non-kosher fowl, he is liable for lashes according to Scriptural Law, as [Leviticus 11:13] states: "These shall you detest from the fowl. You shall not partake of them." And he violates a positive commandment, as [Deuteronomy 14:11] states: "You may partake of all kosher fowl." Implied is that the non-kosher may not be eaten.Anyone who partakes of an olive-sized portion of a non-kosher fish is liable for lashes according to Scriptural Law, as [Leviticus 11:11] states: "They shall be detestable for you. Do not partake of their meat." And he violates a positive commandment, as [Deuteronomy 14:9] states: "All that possess fins and scales, you may eat." Implied is that those that do not possess fins and scales may not be eaten. We thus learn that anyone who partakes of a non-kosher fish, domesticated animal, wild beast, or fowl nullified a positive commandment and violated a negative commandment. (negative commandment 172, 173, 174) and Sefer HaChinuch (mitzvot 154, 156, 157) include these among the 613 mitzvot of the Torah.

חָגָב טָמֵא הֲרֵי הוּא בִּכְלַל שֶׁרֶץ הָעוֹף וְהָאוֹכֵל כְּזַיִת מִשֶּׁרֶץ הָעוֹף לוֹקֶה שֶׁנֶּאֱמַר (דברים יד יט) "כָּל שֶׁרֶץ הָעוֹף טָמֵא הוּא לָכֶם לֹא יֵאָכֵלוּ". וְאֵי זֶהוּ שֶׁרֶץ הָעוֹף כְּגוֹן זְבוּב אוֹ יַתּוּשׁ וְצִרְעָה וּדְבוֹרָה וְכַיּוֹצֵא בָּהֶן:

A non-kosher locust is included among [the category of] flying teeming animals. and others note that, in contrast, to the previous halachot, the Rambam does not mention the fact that there is a prohibition against partaking of locusts that results from the positive commandment to partake of them. One who partakes of an olive-sized portion of flying teeming animals is liable for lashes according to Scriptural Law, as [Deuteronomy 14:19] states: "All flying teeming animals are non-kosher for you. They may not be eaten." (negative commandment 175) and Sefer HaChinuch (mitzvah 471) include this as one of the 613 mitzvot of the Torah.As explained in the halachot that follow and summarized in Halachah 23, there are five prohibitions in the Torah that refer to teeming animals. The categories are not mutually exclusive and it is possible that one particular creature may be included in several - or all - of these categories.What is meant by a flying teeming animal? For example, a fly, a mosquito, a hornet, a bee, or the like.

הָאוֹכֵל כְּזַיִת מִשֶּׁרֶץ הָאָרֶץ לוֹקֶה שֶׁנֶּאֱמַר (ויקרא יא מא) "וְכָל הַשֶּׁרֶץ הַשֹּׁרֵץ עַל הָאָרֶץ שֶׁקֶץ הוּא לֹא יֵאָכֵל". וְאֵי זֶהוּ שֶׁרֶץ הָאָרֶץ כְּגוֹן נְחָשִׁים וְעַקְרַבִּים וְחִפְשִׁית וְנַדָּל וְכַיּוֹצֵא בָּהֶן:

When one partakes of an olive-sized portion of a teeming animal of the land, he is liable for lashes, as [Leviticus 11:41] states: "Any teeming animal that swarms on the ground is detestable to you. It should not be eaten." (negative commandment 176) and Sefer HaChinuch (mitzvah 162) include this as one of the 613 mitzvot of the Torah.What is meant by a teeming animal of the land? Snakes, scorpions, beetles, centipedes, and the like.

וּשְׁמוֹנָה שְׁרָצִים הָאֲמוּרִים בַּתּוֹרָה שֶׁהֵן (ויקרא יא כט) "הַחלֶד וְהָעַכְבָּר וְהַצָּב" (ויקרא יא ל) "וְהָאֲנָקָה וְהַכֹּחַ וְהַלְּטָאָה וְהַחֹמֶט וְהַתִּנְשֶׁמֶת" הָאוֹכֵל מִבְּשָׂרָם כַּעֲדָשָׁה לוֹקֶה. שִׁעוּר אֲכִילָתָן כְּשִׁעוּר טֻמְאָתָן. וְכֻלָּם מִצְטָרְפִין זֶה עִם זֶה בְּכַעֲדָשָׁה:

The eight teeming animals that are mentioned in the Torah 16b). This explains why the minimum measure for which they are liable is less than that associated with other prohibitions. are: the weasel, the mouse, the ferret, the hedgehog, the chameleon, the lizard, the snail, and the mole. A person who eats a lentil-sized portion of their meat is liable for lashes. The minimum measure that one is prohibited to partake of their meat is the same as the minimum measure that conveys ritual impurity. They all may be combined together to reach the measure of a lentil.

בַּמֶּה דְּבָרִים אֲמוּרִים בְּשֶׁאָכַל מֵהֶן אַחַר מִיתָתָן. אֲבָל הַחוֹתֵךְ אֵיבָר מִן הַחַי מִן אֶחָד מֵהֶן וַאֲכָלוֹ אֵינוֹ לוֹקֶה עָלָיו עַד שֶׁיִּהְיֶה בּוֹ כְּזַיִת בָּשָׂר. וְכֻלָּן מִצְטָרְפִין לִכְזַיִת. אָכַל אֵיבָר שָׁלֵם מִן הַשֶּׁרֶץ אַחַר שֶׁמֵּת אֵינוֹ לוֹקֶה עַד שֶׁיִּהְיֶה בּוֹ כַּעֲדָשָׁה:

When does the above apply? When one partakes of them after they have died. If, however, one cuts off a limb from a living creature from one of these species and eats it, he does not receive lashes unless he [partakes of] an olive-sized portion of meat. They all may be combined together to reach the measure of an olive.One who eats an entire limb of a teeming animal after it dies does not receive lashes unless it contains a lentil-sized amount of meat. 4:3 states that there is no minimum measure with regard to the limbs of a teeming animal within the context of ritual impurity. A person who touches an entire limb of a such an animal after its death becomes impure even if the limb is smaller than the size of a lentil. Nevertheless, we do not rule that one is liable if he eats such a limb.Meilah, loc. cit., explains that although the limbs of other animals also convey ritual impurity no matter what their size, one is not liable unless he partakes of an olive-sized portion. Hence, there is no reason to extend the stringency that applies with regard to these teeming animals any further.

דַּם שְׁמוֹנָה שְׁרָצִים וּבְשָׂרָן מִצְטָרֵף לְכַעֲדָשָׁה וְהוּא שֶׁיִּהְיֶה הַדָּם מְחֻבָּר לַבָּשָׂר. וְכֵן דַּם הַנָּחָשׁ מִצְטָרֵף לִבְשָׂרוֹ לִכְזַיִת וְלוֹקֶה עָלָיו לְפִי שֶׁאֵין בְּשָׂרוֹ חָלוּק מִדָּמוֹ. וְאַף עַל פִּי שֶׁאֵינוֹ מְטַמֵּא. וְכֵן כָּל כַּיּוֹצֵא בּוֹ מִשְּׁאָר שְׁרָצִים שֶׁאֵינָן מְטַמְּאִין:

The blood of these eight teeming animals and their flesh can be combined to reach the minimum measure of a lentil, provided the blood is still attached to their flesh. Similarly, the blood of a snake is combined with its flesh to reach the measure of an olive and one receives lashes for it. The rationale is that its flesh is not separate from its blood, even though it does not impart ritual impurity. Similar concepts apply with regard to other teeming animals that do not convey ritual impurity.

דַּם שְׁרָצִים שֶׁפָּרַשׁ וּכְנָסוֹ וַאֲכָלוֹ לוֹקֶה עָלָיו בִּכְזַיִת. וְהוּא שֶׁיַּתְרוּ בּוֹ מִשּׁוּם אוֹכֵל שֶׁרֶץ. אֲבָל אִם הִתְרוּ בּוֹ מִשּׁוּם אוֹכֵל דָּם פָּטוּר. שֶׁאֵין חַיָּבִין אֶלָּא עַל דַּם בְּהֵמָה חַיָּה וְעוֹף:

When a person collects the blood of teeming animals that has been separated [from their bodies] and partakes of it, he receives lashes if he partakes of a portion the size of an olive. (in his gloss to Halachah 9) states that this applies even to the eight teeming animals mentioned explicitly in the Torah. Once their blood is separated from their bodies, the minimum measure is the same as that of other species. [This applies] provided he was warned against partaking of it because [of the prohibition against partaking of] a teeming animal. If, however, he is warned against partaking of it because [of the prohibition against partaking of] blood, he is not liable. For we are liable only for the blood of domesticated animals, wild beasts, and fowl.

כָּל הַשִּׁעוּרִין וּמַחְלְקוֹתָם הֲלָכָה לְמשֶׁה מִסִּינַי:

All these measures - and the distinctions between them - are halachot received by Moses at Sinai [and transmitted via the Oral Tradition].

הָאוֹכֵל כְּזַיִת מִשֶּׁרֶץ הַמַּיִם לוֹקֶה מִן הַתּוֹרָה שֶׁנֶּאֱמַר (ויקרא יא מג) "אַל תְּשַׁקְּצוּ אֶת נַפְשֹׁתֵיכֶם בְּכָל הַשֶּׁרֶץ הַשֹּׁרֵץ וְלֹא תִטַּמְּאוּ בָּהֶם". הֲרֵי כָּלַל בְּלָאו זֶה שֶׁרֶץ הָאָרֶץ וְשֶׁרֶץ הָעוֹף וְשֶׁרֶץ הַמַּיִם. אֵי זֶהוּ שֶׁרֶץ הַמַּיִם אֵלּוּ הַבְּרִיּוֹת הַקְּטַנּוֹת כְּמוֹ הַתּוֹלָעִים וְהָעֲלוּקָה שֶׁבַּמַּיִם וְהַבְּרִיּוֹת הַגְּדוֹלוֹת בְּיוֹתֵר שֶׁהֵן חַיּוֹת הַיָּם. כְּלָלוֹ שֶׁל דָּבָר כָּל שֶׁאֵינוֹ בְּצוּרַת הַדָּגִים לֹא דָּג טָמֵא וְלֹא דָּג טָהוֹר כְּגוֹן כֶּלֶב הַמַּיִם וְהַדַּלְפוֹן וְהַצְּפַרְדֵּעַ וְכַיּוֹצֵא בָּהֶן:

One who partakes of an olive-sized portion of an aquatic teeming animal is liable for lashes according to Scriptural Law, as [Leviticus 11:43] states: "Do not make your souls detestable [by partaking] of any teeming animal that swarms... and do not become impure because of them." Included in this prohibition are teeming animals of the land, that fly, and of the water. (negative commandment 179) and Sefer HaChinuch (mitzvah 164) include this as one of the 613 mitzvot of the Torah. As obvious from the Rambam's words here and as explained in greater length in Sefer HaMitzvot, this is not a specific commandment relating to aquatic teeming creatures, but a general commandment relating to all teeming animals. Accordingly, when a person partakes of a teeming animal of the land or a flying teeming animal, he is liable for two transgressions.The Ramban (Hasagot to Sefer HaMitzvot, General Principle 9) and the Maggid Mishneh differ with the Rambam and maintain that this is not considered as a separate mitzvah.What is meant by a aquatic teeming animal? Both small creatures like worms and leeches that inhabit the water and larger creatures that are beasts of the sea. To state a general principle: Any aquatic creature that does not have the characteristics of a fish, neither a non-kosher fish or a kosher fish, e.g., a seal, a dolphin, a frog, or the like.

אֵלּוּ הַמִּינִין שֶׁנִּבְרָאִין בְּאַשְׁפּוֹת וּבְגוּפֵי הַנְּבֵלוֹת כְּגוֹן רִמָּה וְתוֹלַעַת וְכַיּוֹצֵא בָּהֶן שֶׁאֵינָן נִבְרָאִין מִזָּכָר וּנְקֵבָה אֶלָּא מִן הַגְּלָלִים שֶׁהִסְרִיחוּ וְכַיּוֹצֵא בָּהֶן הֵן הַנִּקְרָאִין רוֹמֵשׂ עַל הָאָרֶץ. וְהָאוֹכֵל מֵהֶן כְּזַיִת לוֹקֶה שֶׁנֶּאֱמַר (ויקרא יא מד) "וְלֹא תְטַמְּאוּ אֶת נַפְשֹׁתֵיכֶם בְּכָל הַשֶּׁרֶץ הָרֹמֵשׂ עַל הָאָרֶץ" וְאַף עַל פִּי שֶׁאֵין פָּרִין וְרָבִין. אֲבָל (ויקרא יא מא מב) "הַשֶּׁרֶץ הַשּׁוֹרֵץ עַל הָאָרֶץ" הוּא שֶׁפָּרֶה וְרָבֶה מִזָּכָר וּנְקֵבָה:

The species that come into existence in garbage heaps and the carcasses of dead animals, e.g., maggots, worms, and the like which are not brought into being from male-female [relations], but from filth that decays and the like are called "those which creep on the earth." A person who partakes of an olive-sized portion [of these creations] is liable for lashes, (negative commandment 177) and Sefer HaChinuch (mitzvah 165) include this as one of the 613 mitzvot of the Torah. as [Leviticus 11:44] states: "Do not make your souls impure with any teeming animal that creeps on the earth," even thought they do not reproduce. Teeming animals that swarm on the earth, by contrast, are those that reproduce from male-female [relations].

אֵלּוּ הַמִּינִין הַנִּבְרָאִין בְּפֵרוֹת וּבְמַאֲכָלוֹת אִם פָּרְשׁוּ וְיָצְאוּ לָאָרֶץ אַף עַל פִּי שֶׁחָזְרוּ לְתוֹךְ הָאֹכֶל מִי שֶׁאָכַל מֵהֶן כְּזַיִת לוֹקֶה שֶׁנֶּאֱמַר (ויקרא יא מב) "לְכָל הַשֶּׁרֶץ הַשֹּׁרֵץ עַל הָאָרֶץ" לֶאֱסֹר אֵלּוּ שֶׁפָּרְשׁוּ לָאָרֶץ. אֲבָל אִם לֹא פָּרְשׁוּ מֻתָּר לֶאֱכל הַפְּרִי וְהַתּוֹלַעַת שֶׁבְּתוֹכוֹ:

[The following laws apply with regard to] species that come into being from fruits and other foods. Should they depart from [the source from where they came into being] and go to the earth, (negative commandment 178). Note, however, Halachah 16. a person who partakes of an olive-sized portion of them is liable for lashes, (negative commandment 178) and Sefer HaChinuch (mitzvah 163) include this as one of the 613 mitzvot of the Torah. as [Leviticus 11:42] states: "With regard to any teeming animal that swarms on the earth, [do not eat them]." This forbids those that departed to the earth, even though they returned to the food. If, however, they did not depart, it is permitted to eat the fruit together with the worm in it.

בַּמֶּה דְּבָרִים אֲמוּרִים שֶׁהִתְלִיעַ הָאֹכֶל אַחַר שֶׁנֶּעֱקַר מִן הָאָרֶץ. אֲבָל אִם הִתְלִיעַ וְהוּא מְחֻבָּר. אוֹתָהּ הַתּוֹלַעַת אֲסוּרָה כְּאִלּוּ פֵּרְשָׁה לָאָרֶץ שֶׁעַל הָאָרֶץ נִבְרֵאת וְלוֹקִין עָלֶיהָ. וְאִם סָפֵק אֲסוּרָה. לְפִיכָךְ כָּל מִינֵי פֵּרוֹת שֶׁדַּרְכָּן לְהַתְלִיעַ כְּשֶׁהֵן מְחֻבָּרִין לֹא יֹאכַל עַד שֶׁיִּבְדֹּק הַפְּרִי מִתּוֹכוֹ שֶׁמָּא יֵשׁ בּוֹ תּוֹלַעַת. וְאִם שָׁהָה הַפְּרִי אַחַר שֶׁנֶּעֱקַר שְׁנֵים עָשָׂר חֹדֶשׁ אוֹכֵל בְּלֹא בְּדִיקָה שֶׁאֵין תּוֹלַעַת שֶׁבּוֹ מִתְקַיֶּמֶת שְׁנֵים עָשָׂר חֹדֶשׁ:

When does the above apply? When the food became worm-ridden after it was uprooted from the earth. If, however, it became worm-ridden while it was connected [to its source of nurture], that worm is forbidden as if it became departed to the earth. For it was created on the earth. One is liable for lashes [for partaking of it]. If there is a doubt, it is forbidden.Therefore all fruits that commonly become worm-ridden when connected [to their source of nurture] should not be eaten until one checks the fruit from its inside, for perhaps it contains a worm. If the fruit remains twelve months after being severed [from its source], it may be eaten without being inspected. For a worm inside of it will not endure for twelve months. (Yoreh De'ah 84:8) states that the produce should be checked lest there be crawling animals that have left the produce. One of the ways to select grains, legumes, and the like is to soak them first. Any ones with holes will float to the top. They should be discarded, lest they be worm-ridden.

פָּרְשׁוּ לָאֲוִיר וְלֹא נָגְעוּ לָאָרֶץ. אוֹ שֶׁפָּרְשׁוּ מִקְצָתָן לָאָרֶץ. אוֹ שֶׁפָּרְשׁוּ אַחַר שֶׁמֵּתוּ. אוֹ שֶׁנִּמְצֵאת תּוֹלַעַת עַל הַגַּרְעִינָה מִבִּפְנִים. אוֹ שֶׁיָּצְאוּ מִתּוֹךְ הָאֹכֶל לְתוֹךְ אֹכֶל אַחֵר. כָּל אֵלּוּ אֲסוּרִין מִסָּפֵק וְאֵין לוֹקִין עֲלֵיהֶן:

If [the worm] departed to the atmosphere, but did not reach the earth, or only a portion of it reached the earth, it departed after it died, the worm was found on the seed on the inside, or it departed from one food to another, [in] all these [situations, the worm] is forbidden because of the doubt, but lashes are not administered [if one partakes of it].

תּוֹלַעַת הַנִּמְצֵאת בִּמְעֵי הַדָּגִים וּבַמֹּחַ שֶׁבְּרֹאשׁ הַבְּהֵמָה וְהַנִּמְצֵאת בַּבָּשָׂר אֲסוּרָה. אֲבָל דָּג מָלִיחַ שֶׁהִתְלִיעַ הֲרֵי הַתּוֹלַעַת שֶׁבּוֹ מֻתֶּרֶת. שֶׁהֵן כְּפֵרוֹת שֶׁהִתְלִיעוּ אַחַר שֶׁנֶּעֶקְרוּ מִן הָאָרֶץ שֶׁמֻּתָּר לְאָכְלָן כֻּלָּן כְּאַחַת בַּתּוֹלַעַת שֶׁבְּתוֹכָן. וְכֵן הַמַּיִם שֶׁבַּכֵּלִים שֶׁהִשְׁרִיצוּ הֲרֵי אוֹתָן שְׁרָצִים מֻתָּר לִשְׁתּוֹתָן עִם הַמַּיִם שֶׁנֶּאֱמַר (ויקרא יא ט) "וְכָל אֲשֶׁר לוֹ סְנַפִּיר וְקַשְׂקֶשֶׂת בַּמַּיִם בַּיַּמִּים וּבַנְּחָלִים אֹתָם תֹּאכֵלוּ". כְּלוֹמַר בַּמַּיִם וּבַיַּמִּים וּבַנְּחָלִים הוּא שֶׁאַתָּה אוֹכֵל אֶת שֶׁיֵּשׁ לוֹ וְאֵין אַתָּה אוֹכֵל אֶת שֶׁאֵין לוֹ. אֲבָל בְּכֵלִים בֵּין שֶׁיֵּשׁ לוֹ בֵּין שֶׁאֵין לוֹ מֻתָּר:

A worm found in the stomach of a fish, in the brain within the head of an animal, and one found in meat are forbidden. When, however, salted fish becomes worm-ridden, the worms in it are permitted.).The Maggid Mishneh explains the Rambam's approach as follows: All worms that are found in both meat and fish while the animals are alive are forbidden, for we assume that they entered from the outside. Even after a fish dies, we can assume that the worms in its stomach were swallowed when it was alive. Similarly, those in an animal's brain can be assumed to have entered its nose from the outside and are hence, forbidden. Those found in the body of a fish are considered to have been spontaneously generated are hence permitted. Those found in the meat of an animal are not permitted. The rationale is that anything that comes from an animal is permitted to be eaten only after it has been slaughtered according to law. Even though the animal itself was slaughtered, since that slaughter preceded the existence of the worms, they are not permitted.The Ra'avad and many other Rishonim differ with the Rambam's understanding and permit worms that came into being in meat from animals that were ritually slaughtered, e.g., in meat that was salted to be used at a later time. The Shulchan Aruch (Yoreh De'ah 84:16) quotes both views, but appears to favor the more lenient one. The Rama states that it is customary to follow the more lenient view. In practice, in the present age, this problem is far less prevalent, for because of refrigeration and freezing, it is less likely for worms to exist in meat. This is comparable to fruit which has become worm-ridden after it has been separated from the earth. It is permitted to eat them together with the worm that is in them.Similarly, if water 84:1). This is evident from Halachot 19-20. in a utensil produces teeming animals, those teeming animals are permitted to be drunk together with the water, as [can be inferred from Leviticus 11:9]: "All that possess fins and scales in the water, seas, and rivers, they you may eat." Implied is that you may eat those that possess [fins and scales] in the water, seas, and rivers and those that do not possess them, you may not eat. But those creatures [that come into existences] in utensils are permitted whether they possess [fins and scales] or not.

שֶׁרֶץ הַמַּיִם הַנִּבְרָא בְּבוֹרוֹת וּבְשִׁיחִין וּבִמְעָרוֹת הוֹאִיל וְאֵינָן מַיִם נוֹבְעִין וַהֲרֵי הֵן עֲצוּרִים הֲרֵי הֵן כְּמַיִם שֶׁבְּכֵלִים וּמֻתָּר. וְשׁוֹחֶה וְשׁוֹתֶה וְאֵינוֹ נִמְנָע וְאַף עַל פִּי שֶׁבּוֹלֵעַ בִּשְׁעַת שְׁתִיָּה מֵאוֹתָן הַשְּׁרָצִים הַדַּקִּים:

[Since the water found] in cisterns, trenches and caves is not flowing water, but instead is collected there, states that irrigation ditches and breeding ponds which water flows through are not included in this category, because - in contrast to water found in containers - the water in them does not stand still. The Shulchan Aruch (Yoreh De'ah 84:1) quotes a difference of opinion on this issue. it is comparable to water found in containers. [Hence], aquatic teeming animals that are created [in these places] are permitted. A person may bend down and drink (Yoreh De'ah 84:2), the Rama states that if one finds worms in a bucket of water drawn from such bodies, the worms are forbidden, because we fear that the worms came from the bucket and not from the water. without holding back even though he swallows these flimsy teeming animals when drinking. 84:1). This is evident from Halachot 19-20.

בַּמֶּה דְּבָרִים אֲמוּרִים שֶׁלֹּא פָּרְשׁוּ מִמְּקוֹם בְּרִיָּתָן. אֲבָל אִם פֵּרַשׁ הַשֶּׁרֶץ אַף עַל פִּי שֶׁחָזַר לְתוֹךְ הַכְּלִי אוֹ לְתוֹךְ הַבּוֹר אָסוּר. פָּרַשׁ לְדָפְנֵי הֶחָבִית וְחָזַר וְנָפַל לְתוֹךְ הַמַּיִם אוֹ לְתוֹךְ הַשֵּׁכָר מֻתָּר. וְכֵן אִם פָּרַשׁ לְדָפְנֵי הַבּוֹר אוֹ הַמְּעָרָה וְחָזַר לַמַּיִם מֻתָּר:

When does the above apply? When the teeming animals did not depart from the place where they came into being. If they did, even though they later return to the container or the cistern, they are forbidden. If they went out to the walls of the barrel and then fell back into the water or the beer, they are permitted. Similarly, if they went out to the walls of the cistern and the cave and returned to the water, they are permitted.

הַמְסַנֵּן אֶת הַיַּיִן אוֹ אֶת הַחֹמֶץ אוֹ אֶת הַשֵּׁכָר וְאָכַל אֶת הַיַּבְחוּשִׁים אוֹ אֶת הַיַּתּוּשִׁין וְהַתּוֹלָעוֹת שֶׁסִּנֵּן לוֹקֶה מִשּׁוּם שֶׁרֶץ הַמַּיִם אוֹ מִשּׁוּם שֶׁרֶץ הָעוֹף (וְשֶׁרֶץ הַמַּיִם) אֲפִלּוּ חָזַר לַכְּלִי אַחַר שֶׁסִּנְּנָן שֶׁהֲרֵי פָּרְשׁוּ מִמְּקוֹם בְּרִיָּתָן. אֲבָל אִם לֹא סִנְּנָן שׁוֹתֶה וְאֵינוֹ נִמְנָע כְּמוֹ שֶׁפֵּרַשְׁנוּ:

When a person strains wine, vinegar, or beer and eats the insects, bugs, and worms that he strains, he is liable for lashes for partaking of an aquatic teeming animal or [for partaking of] a flying teeming animal and an aquatic teeming animal. [This applies] even if they returned to the container after they were strained, for they departed from the place where they came into existence. If, however, they did not depart, one may drink without holding back, as we explained.).

זֶה שֶׁאָמַרְנוּ בְּפֶרֶק זֶה הָאוֹכֵל כְּזַיִת. כְּשֶׁאָכַל כְּזַיִת מִבְּרִיָּה גְּדוֹלָה אוֹ שֶׁצֵּרֵף מְעַט מִבְּרִיָּה זוֹ וּמְעַט מִבְּרִיָּה זוֹ שֶׁבְּמִינָהּ עַד שֶׁיֹּאכַל כְּזַיִת. אֲבָל הָאוֹכֵל בְּרִיָּה טְמֵאָה בִּפְנֵי עַצְמָהּ כֻּלָּהּ הֲרֵי זֶה לוֹקֶה מִן הַתּוֹרָה. וַאֲפִלּוּ הָיְתָה פְּחוּתָה מִן הַחַרְדָּל. בֵּין שֶׁאֲכָלָהּ מֵתָה בֵּין שֶׁאֲכָלָהּ חַיָּה. וַאֲפִלּוּ סָרְחָה הַבְּרִיָּה וְנִשְׁתַּנֵּית צוּרָתָהּ הוֹאִיל וַאֲכָלָהּ כֻּלָּהּ לוֹקֶה:

When, in this chapter, we have spoken about partaking of an olive-sized portion, [the intent is that] one ate an olive-sized portion of a large creature or one collected some from one species and some from another similar species until one partakes of an olive sized portion. If, however, one eats an entire forbidden creature by itself, one is liable for lashes according to Scriptural Law even if it is smaller than a mustard seed.[This applies] whether one partook of it after it died or while it was alive. Even if the creature decayed and lost its form, one is liable for lashes since one consumed it in its entirety.

נְמָלָה שֶׁחֲסֵרָה אֲפִלּוּ אַחַת מֵרַגְלֶיהָ אֵינוֹ לוֹקֶה עָלֶיהָ אֶלָּא בִּכְזַיִת. לְפִיכָךְ הָאוֹכֵל זְבוּב שָׁלֵם אוֹ יַתּוּשׁ שָׁלֵם בֵּין חַי וּבֵין מֵת לוֹקֶה מִשּׁוּם שֶׁרֶץ הָעוֹף:

When an ant has lost even one of its legs, one is not liable for lashes for partaking of it unless one eats an olive-sized portion. For this reason, one who eats an entire fly or an entire mosquito whether alive or dead is worthy of lashes for partaking of a flying teeming animal.

[The following laws apply if] a particular creature is [included in the categories of] a flying teeming animal, an aquatic teeming animal, and a teeming animal of the earth, e.g., it has wings, it walks on the earth like other [earthbound] teeming animals, and it reproduces in the water. If one partakes of it, he is liable for three [sets of] lashes. 16b: "If one eats a potisa, one is liable for four [sets of] lashes, an ant, five [sets of] lashes." As he explains in Sefer HaMitzvot (negative commandment 179), the intent is not that one is liable for additional sets of lashes because several prohibitions are stated with regard to a particular creature. Instead, the intent is that if one creature falls into several forbidden categories, one is liable for a set of lashes for every forbidden category. See Maggid Mishneh.It must be emphasized that the Ra'avad, Rav Moshe HaCohen, the Ramban, and other Rishonim do not accept the Rambam's interpretation and instead, maintain that the prohibitions mentioned in Makkot, loc. cit., refer to the repetition of prohibitions concerning a single creature.If, in addition to the above, it is one of the species which are brought into being in the earth in fruit, he is liable for a fourth [set of] lashes. If it is one of the species that reproduce, he is liable for a fifth [set of] lashes. If it also can be considered as a non-kosher fowl in addition to being considered a flying teeming animal, (loc. cit.), the Rambam is sensitive to the question that might arise and states: "Do not wonder how it is possible for a fowl to come into being from the decay of fruits, for we have seen this take place frequently." In that source, he also explains that it is possible for a single creature to have the characteristics of a non-kosher fowl and a flying teeming animal. he is liable for six [sets of] lashes: [for partaking of] a non-kosher fowl, a flying teeming animal, a teeming animal of the earth, an aquatic teeming animal, an animal that swarms on the earth, and a worm from fruit.[This applies whether] he partook of the entire creature or he partook of an olive-sized portion of it. Therefore one who eats an ant that flies that breeds in the water is liable for five [sets of] lashes.

רִסֵּק נְמָלִים וְהֵבִיא אַחַת שְׁלֵמָה וְצֵרְפָהּ לְאֵלּוּ שֶׁנִּתְרַסְּקוּ וְנַעֲשָׂה הַכּל כְּזַיִת וַאֲכָלוֹ לוֹקֶה שֵׁשׁ מַלְקִיּוֹת. חָמֵשׁ מִשּׁוּם הַנְּמָלָה הָאַחַת וְאַחַת מִשּׁוּם כְּזַיִת מִנִּבְלַת הַטְּמֵאִים:

When one crushed ants, added another complete ant to those that were crushed so that the entire quantity was equal to an olive-sized portion, and partook of it, he is liable for six [sets of] lashes: five [for partaking of] the one ant and an additional one, because he partook of an olive-sized portion of dead non-kosher animals. (in his gloss to that halachah) raises questions with the Rambam's statement here. The Kessef Mishneh and others attempt to offer resolutions.
