Frequently Asked Questions
Why does Costco blade-tenderize their pre-cut steaks?
Costco uses mechanical blade tenderization on pre-cut tray steaks to break down muscle fibers and ensure consistent tenderness for general consumers.
However, this process pushes surface bacteria into the center of the meat, which requires cooking to 145°F according to USDA 9 CFR § 317 regulations to guarantee food safety.
How do I avoid buying blade-tenderized beef at Costco?
You can avoid blade-tenderized beef by purchasing whole, un-cut subprimal loins in sealed Cryovac packaging, such as whole tenderloins, ribeye loins, or New York strip loins. These whole cuts bypass the tenderization machines entirely and carry no mandatory higher internal cooking temperature requirements.
Is buying USDA Prime at Costco really worth the extra cost?
Yes, buying USDA Prime whole subprimal loins at Costco offers exceptional value compared to specialty butcher shops or high-end restaurants.
Since USDA Prime represents the top 10 percent of graded beef in America, purchasing it in bulk allows you to enjoy incredible marbling and tenderness at prices near typical supermarket Choice rates.
How long do whole Cryovac beef loins last in the refrigerator?
Unopened, factory-sealed Cryovac beef loins can safely remain in your refrigerator for several weeks past purchase due to the anaerobic vacuum environment.
Once you open and slice the subprimal cut, wrap individual steaks tightly and freeze them to maintain optimal freshness for up to twelve months.
