Lab-grown meat. but is it kosher?

The Product In Jewish law, a food that contains only a minuscule amount of a non-kosher ingredient can still be considered kosher if the non-kosher ingredient is nullified (usually) by at least a factor of 60 to 1. At first glance it would appear that we can apply this rule to our scenario, since the original cells are greatly outnumbers by the “meat” produced. However, halachah states that the above rule does not apply to a “davar hama’amid,” an ingredient that establishes the form of the item. The essential ingredient can never be nullified, no matter how small it is.12 It would seem that the same rule applies to the cells that are essential to growing the meat. If they don’t come from a kosher source, they can never be nullified, and whatever is created with them is also not kosher.

As noted earlier, these are just preliminary thoughts on the subject. Any halachik ruling would have to come from rabbis who are expert in these matters.

1. Psalms 104:21
2. Rashi explains that this is a species of bird that always seems to be wailing and mourning. Some commentators explain that he meant to admonish his student Rabbi Zera for his excessive asceticism. Rabbi Abbhu felt that the many fasts that Rabbi Zera undertook had taken a toll on his clarity of mind, this being an example of it, see Chavos Ya’ir 152.

6. Shalaha Parshas Vayeishev. He cites this piece of Talmud in relation to the episode of the selling of Joseph by his brothers, which, some explain, was a punishment to Joseph. Thinking that he had seen the brothers eat the limb from a living animal, he went and tattled to his father. However, the Shelah explains that in fact the animal they ate was similar to the one described in the Talmud here, and therefore it did not required slaughter and was also not an issue of Eiver Min Hachai.

  1. I first heard of this a couple of years ago and I have not been able to find an answer. This is not some far fetched fantasy, this is a real possibility that is almost upon us, I hope our Rabbanim will have an answer soon.
