How long does salmonella live on a roll of foil? baked chicken last week, touched foil, using same roll of foil today to bake cinnamon rolls.

Salmonella: These germs can survive for weeks on surfaces if you read the text books. From what you describe however, there was no evidence that the raw chicken had Salmonella to begin with, and the nature of the contact seems sketchy as well. The good news is that ordinary stomach acid kills most 'exposures' to Salmonella (as does cooking!). If you have further concerns, talk to a doc about it.
