Rav Shaman bar Abba said in the name of Rav Idi bar Idi bar Gershom who said it in the name of Levi bar Perata who said it in the name of Rabbi Nahum who said it in the name of Rabbi Biraim who said it in the name of a certain old man named Rabbi Jacob that those of the Nasi's house taught that (cooking) a forbidden egg among 60 (permitted) eggs renders them all forbidden, (but cooking) a forbidden egg among 61 (permitted) eggs renders them all permitted. Rabbi Zera questioned the ruling, but the Gemara cited the definitive ruling: It was stated that Rabbi Helbo said in the name of Rav Huna that with regard to a (forbidden) egg (cooked with permitted ones), if there are 60 besides the (forbidden) one, they are (all) forbidden, but if there are 61 besides the (forbidden) one, they are permitted.
