# If a whole item from a living being is mixed into a mixture it isn’t nullified even one in a thousand.<ref>Chullin 100a says that the sciatic nerve isn’t nullified when in a mixture of other sinews because it a complete item. From here the rishonim extrapolate that all complete items are considered significant and not nullified. This is codified in the Rambam (Maachalot Asurot 16:6), Tur, and Shulchan Aruch YD 100:1.

* Rash (Mishna Trumot 10:8) writes that a complete living item is nullified with an amount 960 times greater than its volume of permitted ingredients. The Rashba (Torat HaBayit 14b) agrees. However, the Rosh (Chullin 7:37) and Ran (Chullin 32b) disagree and say that the mishna Chullin 96b compares the piece that is used to honor guest and a complete item from a living being and a piece that is used to honor guest isn’t nullified even one in a thousand. Shulchan Aruch YD 100:1 and Gra 100:5 rule that a complete item from a living being isn’t nullified even one in a thousand.</ref> For example, an ant, non-kosher bird, sciatic nerve, and a limb that was detached from a kosher animal are considered whole items and not nullified. <ref>Shulchan Aruch YD 100:1</ref>

## It comes from a living being.<ref>Gemara Macot 17a sites the opinion of the Rabbis who disagree with Rabbi Shimon that only a complete item from a living being is significant. The Ritva (Chullin 100a) and Taz 100:1 point out that the concept of a living being found in the area of Malkot is applied on a rabbinic level to nullification. The idea that only a living item is significant for the halacha of biryah is mentioned by the Ran (chullin 36a s.v. garsinan) and Shulchan Aruch 100:1.</ref>

The Ritva (Chullin 100a) and Taz 100:1 point out that the significance of a living being found in the area of Malkot, as is the subject of the discussion between Rabbi Shimon and the Rabbis, is applied on a rabbinic level to nullification.

# An egg with a blood spot potentially is considered a biryah. <ref>The Bet Yosef 110:1 is unsure in understanding the Rambam where just an egg that has an unborn chick is considered a biryah or even an egg with a blood spot is considered a biryah. In the Bedek Habayit he concludes leniently that the egg with a blood spot isn't considered a biryah. The Shach 101:2 argues that it certainly isn't a biryah since it was never a living being. This seems to be the opinion of the Rashba [http://www.hebrewbooks.org/pdfpager.aspx?req=9381&st=&pgnum=209 (Torat Habayit Hakatzar 8a)]. See further in the Bet Yosef 86 and Rambam (Maachalot Asurot 15:19) who implies it is a biryah.</ref>

# If there is a halachic doubt if an item is a biryah it can be nullified, however, if there is a doubt if an item is forbidden but certainly is considered a biryah the item isn't nullified.<ref>Isur Veheter HaAruch 25:7, Taz 100:1</ref>

# An important piece of food that can be used to honor a guest isn't nullified even one in a thousand.<ref>Shulchan Aruch YD 101:1</ref>
# If there is a halachic doubt if an item is an important piece it can be nullified, however, if there is a doubt if an item is forbidden but certainly is considered an important piece the item isn't nullified.<ref>Isur Veheter HaAruch 25:7, Taz 100:1</ref>
