I'm looking to smoke a turkey this weekend so I started researching some recipes. Came across some information that recommended not to smoke a bird larger than 12 pounds. I guess this is due to the amount of time the bird would stay in the danger zone during a long low heat smoke. The bird I currently have is 17.5 pounds. Should I get a different bird? Any advice on how to proceed would be appreciated. Don't want to get anyone sick.
