Once you've gone out and picked your choice cut of beef, it's crucial that you treat it properly from the moment it leaves the grocery store to when it first hits the grill. You don't want to risk compromising your beef because doing so could easily mean a trip to the trash for your steak and another trip to the grocery store for another cut. Food safety isn't something you want to mess around with when it comes to meat. Most of us know better than to under-cook chicken, with ground beef you want to make sure you cook it to at least 71°C (160°F). It's just important that you treat your beef right if you want to end up with a meal that is both safe and tasty.
