Injecting Pork Butt 4 hour rule help.
I have a question about injecting a butt. I have always injected it and let it rest for about 12 hours in fridge or cooler. Today I read something about a 4 hour rule. As I understand it, the rule states that once the muscle is punctured by the injector it should be at or above 140 degrees within 4 hours to prevent bacteria growth. Is keeping it in the refrigerator for 12 hours dangerous? Thanks for the help
