בלשון טומאה ושקץ הנאמר במינים הטמאים נכלל לאסר גם צירן ורוטבן היוצא מהם. (שמיני עה, שמיני פא, שמיני פו)
Ayelet Hashachar, translated by Betzalel Avraham Feinstein, 2021
The language טומאה (unclean) and שקץ (disgusting) that is said with respect to types of unclean meat is there in order to prohibit also the sauce and gravy that comes out of them.
