GMO's and petri dish bacon

I read in Popular Science the other day that scientists have GROWN bacon using pig stem cells in glucose (the stem cells feed on the glucose and grow into bacon). Science creeps me out.
Perhaps there's no logical reason to fear bacon grown in a petri dish- it is probably the same basic substance as bacon grown on a live pig, but it just doesn't seem right. Nor does the idea of all these genetically modified crops we are eating. Can we really be sure that combining dna from one organism with that of a completely different organism will not cause... I don't know... but it's weird, and I want to drop out of the modern world.

Look, the winter is past,
and the rains are over and gone.
The flowers are springing up,
the season of singing birds has come,
and the cooing of turtledoves fills the air.
The fig trees are forming young fruit,
and the fragrant grapevines are blossoming...

Song of Solomon 2:11-13 NLT
