halacha - What if you miss the bracha on shechita?

Se we know that you're supposed to make a bracha on shechita.

What if you didn't? Would we still be allowed to eat the meat?

As has already been established, the blessing should be said immediately before the shechita. If someone slaughtered without a bracha, would they have to say the bracha again after?

Answer

No, the meat would not be forbidden if the blessing was skipped, in most cases. The blessing need not be repeated if it was skipped.

See Simla Chadasha (19:1), who writes:

ואי לית ליה לא יברך אחר השחיטה אפילו תוך כדי דיבור דכיון דראוי היה לברך קודם ודחי נפשיה הואיל ואדחי אדחי אבל השחיטה כשרה אפילו לעצמו ואפילו הזיד ולא בירך ומ״מ אם רואים שהעם פרוצים ומקילים בברכות יש לקנוס המזיד ולאסור אותה שחיטה לו ולהלקותו אבל אחרים מותרים

If the blessing was not made, do not make the blessing after the shechita, even "תוך כדי דיבור" (see this answer for some detail on תוך כדי דיבור), since the blessing is missing, it's over. The שחיטה is valid, in any event -- even for the slaughterer himself, even if he skipped the blessing on purpose. However, if we see that there are many people who are skipping this blessing on purpose, then we will punish someone who skips the blessing on purpose -- we will forbid the meat from that shechita to him, and give him lashes; however, the meat is still allowed to others.

( my translation )

It should be noted that the Mordechai in the beginning of Chullin quotes Eldad Hadani as saying that meat slaughtered without a bracha is "פיגול" (likely a stand-in word for "אסור," similar to "טריף" in our vernacular), though the Mordechai says that it is "חומרא ולא נהגינן כוותיה," a stringency that we do not hold ourselves to. (see also this answer for another rejected ruling of Eldad Hadani)
