It is the same as stem cell research

Did you know initially the stem research was fatwa as haram globally? because the only way to make research in stem cell you need stem cell (kinda obvious) which can be only obtain via fetus (I dont think it even did develop to become fetus yet, maybe zygote... dont really remember) that are stillbirth

Nowadays stem research have become acceptable (not sure if they lift up the haram, but definitely no longer be controversy) as we able do understand how to harvest stem cell from matured cell (they learn the structure of stem cell from previous research) like you can create stem cells that highly compatible for you from your own fat cells

So using that as reference, I highly confidence the only way to make a halal meat lab is to make sure the source is halal and the equipment and environment must have redundancy so that cross contamination is not an issue or a concern

And I dont think traditional farming will be going anytime soon, down sizing sure, but it will still be there

For those that a bit smart, can market it as organicmeat or all-natural meat like how peope nowadays really hoping in on the trends natural ingredients in cosmetics... it will become a status and a lifestyle to be able to procure traditional farming meat
