Kosherizing food....

Today I stumbled upon the topic of kosher foods through the methods that discussions tend to meander. Specifically on how meats are made kosher. It was explained that the meat has to meet certain checks which include a blessing by an authorized source. Now my question is: How do they bless the mass produced meat? Does a guy stand at a spot along the conveyor belt and mumble the words? Or does he go from vat to vat of the stuff and bless it there? Or does he bless it while its still alive? What?

A couple of helpful things from http://jewfaq.org/kashrut.htm -

(note: IANAJ, I just remember websites. And sorry for the massive quoting!)

Those are the things that are MOST relevant to what you ask, but there’s a lot more on dietary laws on jewfaq.org.

Regarding the blessing: To make food kosher, a rabbi does not need to “bless” the food. Food simply needs to adhere to Jewish law regarding kashrus to be kosher. This includes making sure that animal items come only from permitted animals, that permitted parts of the animal are used (i.e. no blood), that milk and meat are not mixed, that the animal does not suffer from certain defects (a hole in the lung, for example), etc.

There is a blessing that is said before an animal is slaughtered, just as a blessing is recited before most of the commandments are performed (i.e. I recite a blessing before attaching a mezzuzah to my doorpost, or before putting n tefillin in the morning.) If there is no slaughter (i.e. vegetable matter and fish), no blessing is required.

So, to answer your question, a blessing is recited before meat is slaughtered. However, I’m fairly certain (but I’ll double check when I get home) that if the blessing is not recited, the meat is still kosher ex post facto.
