Scientists are developing means of growing artificial meat in a petri dish. Does such 'meat' have the halachic status of meat?
The article says that the this meat is created using stem cells from slaughtered animals:
When it comes to nullifying something forbidden that is mixed in with something permitted, there are several conditions that prevent nullification. On of them is called a Davar Hama'amed. From the Star-K's website:
It is possible that these stem cells would be considered a Davar Hama'amed, since the whole concoction is dependent on the stem cells to exist. Since a Davar Hama'amed is never nullified, it doesn't matter how minute the stems cells are, they would still make the final product meat, and therefore subject to all the regulations thereof.
I remember the Rav of our shul was a Rav in Switzerland during the war and they had banned shechitah. They relied for meat on a herd of specially raised cows. These were cows that as calves were still in the mothers womb, when the mother was schected. They apparently managed to get a herd of these animals and their offspring that did not require schetiah. So I wonder if you started with meat from a schected animal is a similar issue would apply.
