A consumermarket labgrown meat was tested in the Netherlands for over three decades, as they wanted to be absolutely sure that the genepool used was varied enough to maintain the quality of the meat, and that no unforeseen mutations would suddenly pop up, messing up meatproduction or worse, more. I don't believe the antibiotic resistance was too much of an issue over that period.

Too bad they pulled the plug on the product in the end, due to production costs making and market assessment it would still be too expensive to be sold as a viable alternate meat-option. But as far as I know, it's over three decades of growing meat in a lab, good and safe enough for human consumption.
