בריה שאני:
The Gemara answers that the sciatic nerve is a distinct entity, and therefore it is different in that it is not subject to nullification.
וכן חתיכה של נבלה [וכו’]: ותבטיל ברובא
§ The mishna states: And similarly, in the case of a piece of an animal carcass or a piece of non-kosher fish that was cooked with similar pieces of kosher meat or fish, when one identifies the forbidden piece and removes it, the rest of the meat or fish is forbidden only if the forbidden piece was large enough to impart flavor to the entire mixture. And if he does not identify and remove the forbidden piece, all the pieces are forbidden, due to the possibility that each piece one selects might be the forbidden piece. The Gemara challenges: Even if the piece of an animal carcass was not removed, let it be nullified by a simple majority, as the majority of the pieces are kosher.
הניחא למאן דאמר כל שדרכו לימנות שנינו אלא למ”ד את שדרכו לימנות שנינו מאי איכא למימר שאני חתיכה הואיל וראויה להתכבד בה לפני האורחים
The Gemara clarifies its challenge. This ruling works out well according to the one who said that we learned: Any item whose manner is to be counted, i.e., that is sometimes sold by unit rather than by weight or volume, is considered significant and therefore is not subject to nullification. But according to the one who said that we learned: It is only an item whose manner is exclusively to be counted, i.e., that is always sold by unit, that is considered significant, and is therefore not subject to nullification, what can be said? Since pieces of meat or fish are not always sold by unit, they should be subject to nullification. The Gemara answers: A piece of meat or fish is different, since it is suitable to give honor with it by placing it before guests. Therefore, due to its significance it is not subject to nullification.
וצריכא דאי אשמעינן גיד משום דבריה היא אבל חתיכה אימא לא
The Gemara adds: And it was necessary for the mishna to teach both the halakha that the sciatic nerve is not nullified and the halakha that a piece of non-kosher meat or fish is not nullified, as if the mishna had taught us only the case of a sciatic nerve, one might think that it is not nullified because it is a distinct entity, but in the case of a piece of non-kosher meat, say it is not significant, and it is subject to nullification.
ואי אשמעינן חתיכה הואיל וראויה להתכבד בה לפני האורחים אבל גיד אימא לא צריכא
And if the mishna had taught us the halakha only in the case of a piece of non-kosher meat or fish, one might think that it is not nullified since it is suitable to give honor with it by placing it before the guests. But in the case of a sciatic nerve, say it is not significant, and it is subject to nullification. Therefore it was necessary for the mishna to teach both cases.
דרש רבה בר בר חנה חתיכה של נבלה ושל דג טמא אינה אוסרת עד שתתן טעם ברוטב ובקיפה ובחתיכות
§ Rabba bar bar Ḥana taught: A piece of meat of an unslaughtered carcass or of a non-kosher species of fish that fell into a pot of kosher food does not render the contents of the pot forbidden unless it imparts flavor to the broth and to the deposits of food remaining in the pot and to the other pieces of food in the pot.
אוקי רב אמורא עליה ודרש כיון שנתן טעם בחתיכה חתיכה עצמה נעשת נבלה ואוסרת כל החתיכות כולן מפני שהן מינה
Rav disagreed with Rabba bar bar Ḥana and appointed a disseminator to stand before him and teach his statement to a wider audience, and he taught: Once the non-kosher meat or fish has imparted flavor to another piece in the pot, that second piece itself becomes non-kosher. And this second piece renders all the pieces of meat or fish in the pot forbidden, because they are of the same type; therefore, nullification does not apply.
אמר ליה רב ספרא לאביי מכדי רב כמאן אמרה לשמעתיה כרבי יהודה דאמר מין במינו לא בטיל מאי איריא כי נתן טעם אפילו כי לא נתן טעם נמי אמר ליה הכא במאי עסקינן בשקדם וסלקו
Rav Safra said to Abaye: Now, in accordance with whose opinion did Rav say his statement? It is in accordance with the opinion of Rabbi Yehuda, who says that a type of food mixed with food of its own type is not nullified. But if so, why does Rav state specifically that the non-kosher meat renders all the pieces forbidden only when it has imparted flavor to another piece? Even if it did not impart flavor to another piece it should render all the contents of the pot forbidden. Abaye said to him: Here we are dealing with a case where he cooked the non-kosher piece with one kosher piece and first removed the non-kosher piece before adding the other pieces. Consequently, the remaining pieces are forbidden only if the non-kosher piece imparted flavor to the piece it was cooked with.
רבא אמר
Rava said an alternate answer to Rav Safra’s challenge of Rav’s statement:
אפילו תימא לא קדם וסלקו הוי מין ומינו ודבר אחר
You may even say that it is referring to a case where he did not first remove the piece of non-kosher meat or fish. Nevertheless, this is a case of a mixture of one type of food with its own type of food and with something else, i.e., the spices and broth in the pot.
וכל מין ומינו ודבר אחר סלק את מינו כמי שאינו ושאין מינו רבה עליו ומבטלו:
And in any case of a type of forbidden food mixed with its own type of food and with something else, disregard the food that is its own type, as though it is not present in the mixture, and if the amount of permitted food that is not its own type is sixty times greater than the forbidden food, the permitted food nullifies it. Rav’s ruling applies to a case where the forbidden piece of meat or fish imparts flavor to another piece before the spices and broth are added, and there is a total volume sixty times greater than the original non-kosher piece. Consequently, even if the amount of spices and broth is eventually sixty times greater than the original non-kosher piece of meat or fish, the entire mixture is forbidden, as the spices and broth are not sixty times greater than the two pieces of meat or fish which are now non-kosher.
מתני׳ נוהג בטהורה ואינו נוהג בטמאה רבי יהודה אומר אף בטמאה אמר ר’ יהודה והלא מבני יעקב נאסר גיד הנשה ועדיין בהמה טמאה מותרת להן אמרו לו בסיני נאמר אלא שנכתב במקומו:
MISHNA: The prohibition of eating the sciatic nerve applies to a kosher animal and does not apply to a non-kosher animal. Rabbi Yehuda says: It applies even to a non-kosher animal. Rabbi Yehuda said in explanation: Wasn’t the sciatic nerve forbidden for the children of Jacob, as it is written: “Therefore the children of Israel eat not the sciatic nerve” (Genesis 32:33), yet the meat of a non-kosher animal was still permitted to them? Since the sciatic nerve of non-kosher animals became forbidden at that time, it remains forbidden now. The Rabbis said to Rabbi Yehuda: The prohibition was stated in Sinai, but it was written in its place, in the battle of Jacob and the angel despite the fact that the prohibition did not take effect then.
גמ׳ וסבר ר’ יהודה איסור חל על איסור והתניא ר’ יהודה אומר יכול תהא נבלת עוף טמא מטמא בגדים בבית הבליעה
GEMARA: The Gemara asks: And does Rabbi Yehuda hold that a prohibition takes effect where another prohibition already exists? But isn’t it taught in a baraita: Rabbi Yehuda says: One might have thought that the carcass of a non-kosher bird renders the garments of one who swallows it ritually impure when it is in the throat, similar to the carcass of a kosher bird.
תלמוד לומר (ויקרא כב, ח) נבלה וטרפה לא יאכל לטמאה בה מי שאיסורו משום בל תאכל נבלה יצא זה שאין איסורו משום בל תאכל נבלה אלא משום בל תאכל טמאה
Therefore the verse states concerning the impurity of carcasses of birds: “A carcass, or that which is torn of animals, he shall not eat to defile himself with it” (Leviticus 22:8). The verse indicates that only those birds that are forbidden specifically due to the prohibition: You shall not eat of a carcass, i.e., kosher birds that died without ritual slaughter, cause impurity in this manner. This serves to exclude any bird that is not forbidden due to the prohibition: You shall not eat of a carcass, but rather due to the prohibition: You shall not eat a non-kosher bird. This indicates that according to Rabbi Yehuda, the prohibition of eating a carcass does not take effect with regard to a non-kosher bird, because it is already subject to a different prohibition.
וכי תימא קסבר אין בגידין בנותן טעם ובטמאה נמי איסור גיד איכא איסור טומאה ליכא
The Gemara continues with its question: And if you would say that Rabbi Yehuda holds that sciatic nerves do not impart flavor, i.e., they do not have flavor and therefore are not classified as food, and even with regard to a non-kosher animal it is prohibited to eat the sciatic nerve because the general prohibition of eating a sciatic nerve applies, whereas the prohibition of eating non-kosher animals does not apply because the sciatic nerve is not considered food, this is untenable.
וסבר ר’ יהודה אין בגידין בנותן טעם והתניא האוכל גיד הנשה של בהמה טמאה ר’ יהודה מחייב שתים ור”ש פוטר
The Gemara explains: And does Rabbi Yehuda hold that sciatic nerves do not impart flavor? But isn’t it taught in a baraita: With regard to one who eats the sciatic nerve of a non-kosher animal, Rabbi Yehuda deems him liable to receive two sets of lashes, one for eating the sciatic nerve and one for eating the meat of a non-kosher animal, and Rabbi Shimon exempts him entirely from lashes. This indicates that Rabbi Yehuda holds that the sciatic nerve does have flavor.
לעולם קסבר יש בגידין בנותן טעם וקסבר נוהג בשליל דאיסור גיד ואיסור טומאה בהדי הדדי קאתי
The Gemara answers: Actually Rabbi Yehuda holds that sciatic nerves do impart flavor, and he also holds that the prohibition of eating the sciatic nerve applies to the sciatic nerve of an animal fetus. Consequently, although Rabbi Yehuda holds that a prohibition does not take effect where another already exists, one who eats the sciatic nerve of a non-kosher animal is flogged twice, because the prohibition of eating a sciatic nerve and the prohibition of eating meat from a non-kosher animal come into effect at the same time.
ומי מצית אמרת נוהג בשליל והתנן נוהג בשליל ר’ יהודה אומר אינו נוהג בשליל וחלבו מותר
The Gemara challenges this answer: And can you say that Rabbi Yehuda holds that the prohibition of eating a sciatic nerve applies to the sciatic nerve of a fetus? But didn’t we learn in a mishna (89b): The prohibition applies to a late-term fetus in the womb. Rabbi Yehuda says: It does not apply to a fetus, and similarly the fat of a fetus is permitted?
הני מילי גבי טהורה דרחמנא אמר (דברים יד, ו) כל בבהמה תאכלו אבל בטמאה נוהג
The Gemara answers: This statement, that the prohibition of eating the sciatic nerve does not apply to a fetus, is with regard to a kosher species of animal, because the Merciful One stated in the Torah: “And every animal that divides the hoof, and has the hoof wholly cloven in two, and chews the cud, among the animals [babehema], that you may eat” (Deuteronomy 14:6). The term babehema may also be translated as: Inside the animals, indicating that anything inside a kosher animal when it is slaughtered is permitted for consumption, including all parts of a fetus. But with regard to a non-kosher species of animal the prohibition applies.
ומי מצית אמרת דתרוייהו בהדי הדדי קאתו והתנן על אלו טומאות הנזיר מגלח על המת ועל כזית מן המת
The Gemara challenges the assertion that the prohibitions of eating the sciatic nerve and of eating non-kosher meat take effect at the same time. And can you say that they both come into effect at the same time? But didn’t we learn in a mishna (Nazir 49b): A nazirite shaves for having become impure from these following sources of ritual impurity: For having become impure with impurity imparted by a corpse; and for impurity imparted by an olive-bulk of a corpse.
וקשיא לן על כזית מן המת מגלח על המת כולו לא כ”ש וא”ר יוחנן לא נצרכא אלא לנפל שלא נתקשרו אבריו בגידין אלמא איסור טומאה קדים
And this poses a difficulty for us: If a nazirite shaves for becoming impure from an olive-bulk of a corpse, is it not obvious that all the more so he must shave for becoming impure from an entire corpse? And Rabbi Yoḥanan said: It is necessary only with regard to a miscarried fetus whose limbs have not yet become joined to its sinews. Although the fetus does not yet contain an olive-bulk of flesh, since it is a complete entity, it transmits impurity to anything under the same roof. Evidently, the limbs of the body are formed before the nerves and sinews, and therefore the prohibition of eating non-kosher meat takes effect prior to the prohibition of the sciatic nerve.
אע”ג דאיסור טומאה קדים אתי איסור גיד חייל עליה שכן איסורו נוהג בבני נח
The Gemara answers: Even though the prohibition of eating non-kosher meat takes effect prior to the prohibition of eating the sciatic nerve, the prohibition of the sciatic nerve also comes and takes effect upon a non-kosher animal because this prohibition applies to descendants of Noah, i.e., to gentiles. Since the prohibition of eating the sciatic nerve adds an additional stringency that did not exist with regard to non-kosher meat, it takes effect even though there was an already existing prohibition.
דיקא נמי דקתני א”ר יהודה והלא מבני יעקב נאסר גיד הנשה ועדיין בהמה טמאה מותרת להם
According to this answer, the language of the mishna is also precise, as it teaches: Rabbi Yehuda said: Wasn’t the sciatic nerve forbidden for the children of Jacob, as it is written: “Therefore the children of Israel eat not the sciatic nerve” (Genesis 32:33), yet the meat of a non-kosher animal was still permitted to them? This indicates that the basis of Rabbi Yehuda’s opinion is the fact that the sciatic nerve was forbidden to the children of Jacob, who had the status of descendants of Noah.
גופא האוכל גיד הנשה של בהמה טמאה רבי יהודה מחייב שתים
§ The Gemara returns to the matter itself cited above. With regard to one who eats the sciatic nerve of a non-kosher animal, Rabbi Yehuda deems him liable to receive two sets of lashes: One for eating the sciatic nerve and one for eating the meat of a non-kosher animal;

Meet the diverse women learning Gemara at Hadran and hear their stories.
Ive been learning Gmara since 5th grade and always loved it. Have always wanted to do Daf Yomi and now with Michelle Farber’s online classes it made it much easier to do! Really enjoying the experience thank you!!
Lisa Lawrence

As Jewish educator and as a woman, I’m mindful that Talmud has been kept from women for many centuries. Now that we are privileged to learn, and learning is so accessible, it’s my intent to complete Daf Yomi. I am so excited to keep learning with my Hadran community.

Last cycle, I listened to parts of various מסכתות. When the הדרן סיום was advertised, I listened to Michelle on נידה. I knew that בע”ה with the next cycle I was in (ב”נ). As I entered the סיום (early), I saw the signs and was overcome with emotion. I was randomly seated in the front row, and I cried many times that night. My choice to learn דף יומי was affirmed. It is one of the best I have made!

I’ve been studying Talmud since the ’90s, and decided to take on Daf Yomi two years ago. I wanted to attempt the challenge of a day-to-day, very Jewish activity. Some days are so interesting and some days are so boring. But I’m still here.

In January 2020 on a Shabbaton to Baltimore I heard about the new cycle of Daf Yomi after the siyum celebration in NYC stadium. I started to read “ a daily dose of Talmud “ and really enjoyed it . It led me to google “ do Orthodox women study Talmud? “ and found HADRAN! Since then I listen to the podcast every morning, participate in classes and siyum. I love to learn, this is amazing! Thank you

Retirement and Covid converged to provide me with the opportunity to commit to daily Talmud study in October 2020. I dove into the middle of Eruvin and continued to navigate Seder Moed, with Rabannit Michelle as my guide. I have developed more confidence in my learning as I completed each masechet and look forward to completing the Daf Yomi cycle so that I can begin again!
Rhona Fink

When the new cycle began, I thought, If not now, when? I’d just turned 72. I feel like a tourist on a tour bus passing astonishing scenery each day. Rabbanit Michelle is my beloved tour guide. When the cycle ends, I’ll be 80. I pray that I’ll have strength and mind to continue the journey to glimpse a little more. My grandchildren think having a daf-learning savta is cool!

I went to day school in Toronto but really began to learn when I attended Brovenders back in the early 1980’s. Last year after talking to my sister who was learning Daf Yomi, inspired, I looked on the computer and the Hadran site came up. I have been listening to each days shiur in the morning as I work. I emphasis listening since I am not sitting with a Gamara. I listen while I work in my studio.
Rachel Rotenberg
Tekoa, Israel
It happened without intent (so am I yotzei?!) – I watched the women’s siyum live and was so moved by it that the next morning, I tuned in to Rabbanit Michelle’s shiur, and here I am, still learning every day, over 2 years later. Some days it all goes over my head, but others I grasp onto an idea or a story, and I ‘get it’ and that’s the best feeling in the world. So proud to be a Hadran learner.
Jeanne Yael Klempner
Zichron Yaakov, Israel
I am a Reform rabbi and took Talmud courses in rabbinical school, but I knew there was so much more to learn. It felt inauthentic to serve as a rabbi without having read the entire Talmud, so when the opportunity arose to start Daf Yomi in 2020, I dove in! Thanks to Hadran, Daf Yomi has enriched my understanding of rabbinic Judaism and deepened my love of Jewish text & tradition. Todah rabbah!
Rabbi Nicki Greninger
California, United States
I was inspired to start learning after attending the 2020 siyum in Binyanei Hauma. It has been a great experience for me. It’s amazing to see the origins of stories I’ve heard and rituals I’ve participated in my whole life. Even when I don’t understand the daf itself, I believe that the commitment to learning every day is valuable and has multiple benefits. And there will be another daf tomorrow!
Khaya Eisenberg

I saw an elderly man at the shul kiddush in early March 2020, celebrating the siyyum of masechet brachot which he had been learning with a young yeshiva student. I thought, if he can do it, I can do it! I began to learn masechet Shabbat the next day, Making up masechet brachot myself, which I had missed. I haven’t missed a day since, thanks to the ease of listening to Hadran’s podcast!
Judith Shapiro
Minnesota, United States
I began learning with Rabbanit Michelle’s wonderful Talmud Skills class on Pesachim, which really enriched my Pesach seder, and I have been learning Daf Yomi off and on over the past year. Because I’m relatively new at this, there is a “chiddush” for me every time I learn, and the knowledge and insights of the group members add so much to my experience. I feel very lucky to be a part of this.
Julie Landau
Karmiel, Israel
I started last year after completing the Pesach Sugiyot class. Masechet Yoma might seem like a difficult set of topics, but for me made Yom Kippur and the Beit HaMikdash come alive. Liturgy I’d always had trouble connecting with took on new meaning as I gained a sense of real people moving through specific spaces in particular ways. It was the perfect introduction; I am so grateful for Hadran!

In January 2020, my chevruta suggested that we “up our game. Let’s do Daf Yomi” – and she sent me the Hadran link. I lost my job (and went freelance), there was a pandemic, and I am still opening the podcast with my breakfast coffee, or after Shabbat with popcorn. My Aramaic is improving. I will need a new bookcase, though.
Rhondda May
Atlanta, Georgia, United States
I started learning daf in January, 2020, being inspired by watching the Siyyum Hashas in Binyanei Haumah. I wasn’t sure I would be able to keep up with the task. When I went to school, Gemara was not an option. Fast forward to March, 2022, and each day starts with the daf. The challenge is now learning the intricacies of delving into the actual learning. Hadran community, thank you!
Rochel Cheifetz
Riverdale, NY, United States
I started to listen to Michelle’s podcasts four years ago. The minute I started I was hooked. I’m so excited to learn the entire Talmud, and think I will continue always. I chose the quote “while a woman is engaged in conversation she also holds the spindle”. (Megillah 14b). It reminds me of all of the amazing women I learn with every day who multi-task, think ahead and accomplish so much.

After enthusing to my friend Ruth Kahan about how much I had enjoyed remote Jewish learning during the earlier part of the pandemic, she challenged me to join her in learning the daf yomi cycle. I had always wanted to do daf yomi but now had no excuse. The beginning was particularly hard as I had never studied Talmud but has become easier, as I have gained some familiarity with it.

תלמוד לומר (ויקרא כב, ח) נבלה וטרפה לא יאכל לטמאה בה מי שאיסורו משום בל תאכל נבלה יצא זה שאין איסורו משום בל תאכל נבלה אלא משום בל תאכל טמאה
Therefore the verse states concerning the impurity of carcasses of birds: “A carcass, or that which is torn of animals, he shall not eat to defile himself with it” (Leviticus 22:8). The verse indicates that only those birds that are forbidden specifically due to the prohibition: You shall not eat of a carcass, i.e., kosher birds that died without ritual slaughter, cause impurity in this manner. This serves to exclude any bird that is not forbidden due to the prohibition: You shall not eat of a carcass, but rather due to the prohibition: You shall not eat a non-kosher bird. This indicates that according to Rabbi Yehuda, the prohibition of eating a carcass does not take effect with regard to a non-kosher bird, because it is already subject to a different prohibition.
וכי תימא קסבר אין בגידין בנותן טעם ובטמאה נמי איסור גיד איכא איסור טומאה ליכא
The Gemara continues with its question: And if you would say that Rabbi Yehuda holds that sciatic nerves do not impart flavor, i.e., they do not have flavor and therefore are not classified as food, and even with regard to a non-kosher animal it is prohibited to eat the sciatic nerve because the general prohibition of eating a sciatic nerve applies, whereas the prohibition of eating non-kosher animals does not apply because the sciatic nerve is not considered food, this is untenable.
וסבר ר’ יהודה אין בגידין בנותן טעם והתניא האוכל גיד הנשה של בהמה טמאה ר’ יהודה מחייב שתים ור”ש פוטר
The Gemara explains: And does Rabbi Yehuda hold that sciatic nerves do not impart flavor? But isn’t it taught in a baraita: With regard to one who eats the sciatic nerve of a non-kosher animal, Rabbi Yehuda deems him liable to receive two sets of lashes, one for eating the sciatic nerve and one for eating the meat of a non-kosher animal, and Rabbi Shimon exempts him entirely from lashes. This indicates that Rabbi Yehuda holds that the sciatic nerve does have flavor.
לעולם קסבר יש בגידין בנותן טעם וקסבר נוהג בשליל דאיסור גיד ואיסור טומאה בהדי הדדי קאתי
The Gemara answers: Actually Rabbi Yehuda holds that sciatic nerves do impart flavor, and he also holds that the prohibition of eating the sciatic nerve applies to the sciatic nerve of an animal fetus. Consequently, although Rabbi Yehuda holds that a prohibition does not take effect where another already exists, one who eats the sciatic nerve of a non-kosher animal is flogged twice, because the prohibition of eating a sciatic nerve and the prohibition of eating meat from a non-kosher animal come into effect at the same time.
ומי מצית אמרת נוהג בשליל והתנן נוהג בשליל ר’ יהודה אומר אינו נוהג בשליל וחלבו מותר
The Gemara challenges this answer: And can you say that Rabbi Yehuda holds that the prohibition of eating a sciatic nerve applies to the sciatic nerve of a fetus? But didn’t we learn in a mishna (89b): The prohibition applies to a late-term fetus in the womb. Rabbi Yehuda says: It does not apply to a fetus, and similarly the fat of a fetus is permitted?
הני מילי גבי טהורה דרחמנא אמר (דברים יד, ו) כל בבהמה תאכלו אבל בטמאה נוהג
The Gemara answers: This statement, that the prohibition of eating the sciatic nerve does not apply to a fetus, is with regard to a kosher species of animal, because the Merciful One stated in the Torah: “And every animal that divides the hoof, and has the hoof wholly cloven in two, and chews the cud, among the animals [babehema], that you may eat” (Deuteronomy 14:6). The term babehema may also be translated as: Inside the animals, indicating that anything inside a kosher animal when it is slaughtered is permitted for consumption, including all parts of a fetus. But with regard to a non-kosher species of animal the prohibition applies.
ומי מצית אמרת דתרוייהו בהדי הדדי קאתו והתנן על אלו טומאות הנזיר מגלח על המת ועל כזית מן המת
The Gemara challenges the assertion that the prohibitions of eating the sciatic nerve and of eating non-kosher meat take effect at the same time. And can you say that they both come into effect at the same time? But didn’t we learn in a mishna (Nazir 49b): A nazirite shaves for having become impure from these following sources of ritual impurity: For having become impure with impurity imparted by a corpse; and for impurity imparted by an olive-bulk of a corpse.
וקשיא לן על כזית מן המת מגלח על המת כולו לא כ”ש וא”ר יוחנן לא נצרכא אלא לנפל שלא נתקשרו אבריו בגידין אלמא איסור טומאה קדים
And this poses a difficulty for us: If a nazirite shaves for becoming impure from an olive-bulk of a corpse, is it not obvious that all the more so he must shave for becoming impure from an entire corpse? And Rabbi Yoḥanan said: It is necessary only with regard to a miscarried fetus whose limbs have not yet become joined to its sinews. Although the fetus does not yet contain an olive-bulk of flesh, since it is a complete entity, it transmits impurity to anything under the same roof. Evidently, the limbs of the body are formed before the nerves and sinews, and therefore the prohibition of eating non-kosher meat takes effect prior to the prohibition of the sciatic nerve.
אע”ג דאיסור טומאה קדים אתי איסור גיד חייל עליה שכן איסורו נוהג בבני נח
The Gemara answers: Even though the prohibition of eating non-kosher meat takes effect prior to the prohibition of eating the sciatic nerve, the prohibition of the sciatic nerve also comes and takes effect upon a non-kosher animal because this prohibition applies to descendants of Noah, i.e., to gentiles. Since the prohibition of eating the sciatic nerve adds an additional stringency that did not exist with regard to non-kosher meat, it takes effect even though there was an already existing prohibition.
דיקא נמי דקתני א”ר יהודה והלא מבני יעקב נאסר גיד הנשה ועדיין בהמה טמאה מותרת להם
According to this answer, the language of the mishna is also precise, as it teaches: Rabbi Yehuda said: Wasn’t the sciatic nerve forbidden for the children of Jacob, as it is written: “Therefore the children of Israel eat not the sciatic nerve” (Genesis 32:33), yet the meat of a non-kosher animal was still permitted to them? This indicates that the basis of Rabbi Yehuda’s opinion is the fact that the sciatic nerve was forbidden to the children of Jacob, who had the status of descendants of Noah.
גופא האוכל גיד הנשה של בהמה טמאה רבי יהודה מחייב שתים
§ The Gemara returns to the matter itself cited above. With regard to one who eats the sciatic nerve of a non-kosher animal, Rabbi Yehuda deems him liable to receive two sets of lashes: One for eating the sciatic nerve and one for eating the meat of a non-kosher animal;
