יֵשׁ אוֹמְרִים שֶׁאִם שָׁחַט בְּגּוּמָא בַּשּׁוּק, אָסוּר לֶאֱכֹל מִשְּׁחִיטָתוֹ עַד שֶׁיִּבְדְּקוּ אַחֲרָיו שֶׁמֶּא אֶפִּיקוֹרְס הוּא; וְיֵשׁ אוֹמְרִים שֶׁמֻּתָּר בְּדִיעֲבַד וְאֵין צָרִיךְ בְּדִיקָה

There are those who say that if you slaughter in a basin in the market, it is forbidden to eat what he (the person) slaughters until afterwards we check if he is a heretic (or not). There are those who say that it is permitted after the fact without checking (the character of) the slaughterer.
