Hey Toon! It looks like we're getting closer and closer to the point where this stops being sci-fi and starts being real, but... Can vat-grown meat be kosher?
Heeeey! This question has been asked an awful lot over the years, and the short answer is: possibly, depending.
The long answer is extremely long and includes such factors as:
- is the meat grown from a cell taken from a kosher animal?
- was the kosher animal alive when the cell was taken?
- if so, does that count as the prohibition of eiver min hachai (eating the meat of a still-living animal)?
- if not, was the kosher animal slaughtered according to halachic requirements?
- what is the meat grown on?
- is the meat considered living while still in the vat, and if so, how does one properly slaughter it?
- probably a bunch more stuff that has slipped my mind
And of course, there is widespread disagreement as to which factors are relevant, and what solutions will be acceptable. But most authorities agree that it is at least theoretically possible for vat-grown meat to be made in such a way as to be kosher.
Of course, the next question is whether vat-grown meat counts as meat or not. (Spoiler: there is widespread disagreement.)
