Just watched an episode of this where he frequently handled raw beef & then went on to dip his fingers in bowls of salt, pepper, open cupboards, the fridge, without washing his hands. I think he used the same chopping board to cut the cooked steak that he’d previously flopped the uncooked meat around on. He just about made it in 20 minutes by shaving off some time by not washing his hands. I’m not particularly fastidious but seems a bit unsanitary.
