Yoreh Deah Siman 25 Seif 1

 

סימן כה – שצריך לבדוק אחר השחיטה, ובו ג’ סעיפים

Siman 25 That one must check the signs (the trachea and esophagus) after one has ritually slaughtered

א הַשּׁוֹחֵט צָרִיךְ שֶׁיִּבְדֹק בַּסִימָנִים אַחַר שְׁחִיטָה אִם נִשְׁחֲטוּ רֻבָּן, אוֹ שֶׁיִּרְאֶה בִּשְׁעַת שְׁחִיטָה שֶׁהֵם שְׁחוּטִין רֻבָּן; וְאִם לֹא רָאָה שֶׁרֻבָּן שְׁחוּטִין,אָסוּר. וְיֵשׁ מִי שֶׁאוֹמֵר שֶׁצָּרִיךְ לִרְאוֹת שֶׁהֵם שְׁחוּטִין בִּמְקוֹם שְׁחִיטָה בְּלֹא הַגְרָמָה.

 

Seif 1

A slaughterer must check the signs (that make an animal fit) after slaughter to see is they was slaughtered completely/properly/a sizeable amount. Or if you see during the slaughter that they slaughtered completely, and if you don’t see that it was done completely and it prohibited. There are those who say that one needs to see them slaughter on the proper spot of slaughter and not on the part where it is not fit to slaughter.
