I may not be reading this correctly.
According to the FDA Food Code Chapter 3-401.11 a time/temp chart exists for cooking whole meat roasts.
I get that the mechanical tenderization process classifies a Costco steak as "ground meat" and not "whole meat" for FDA purposes. But if holding at 130* for 112 minutes kills surface bacteria and pathogens wouldn't holding at a core temp of 130* for 112 minutes also kill off the same bacteria and pathogens interspersed throughout the ground meat?
Like, you cook a steak to 135* for medium rare because the outer edge exceeds 160*, killing pathogens, and the inner core is untainted if handled properly. You cook a frozen burger patty to 160* all the way through because the pathogens are possibly interspersed throughout and you need to hit 160* for insta-kill.
But the FDA admits you don't need insta-kill, that's just the easiest method. It's hard to hold a frozen burger patty at 150* properly for 1 minute on a 600* grill or cast iron; most people would end up overcooking it. Same with a Costco steak, how are you going to hold it at 135* internal for an hour, even in a 350* oven doing reverse sear?
But what about everyone's favorite steak cooking method, sous vide? If I drop a Costco steak into a 135* bath for 3-4 hours I'm sure the core internal has held for the requisite time. In effect my sous vide Costco steak is "pasteurized" to safety without affecting flavor or texture. An I missing something?
