You need to wait 48 hours after feeding to handle any snake. You can move them from a feeding tub back to their enclosure, but there should be no other interacting for 48 hours.
That said, I agree with everyone else that feeding outside the enclosure is unnecessary. All feedings should just be supervised, especially if you have a substrate that could be ingested, you want to keep an eye on your snake incase you need to pull a wood chip off their food before it is swallowed.
