So without much ado, let’s dive in and figure out more about it.
How long can a prime rib roast stay in the fridge?
Raw prime rib roast lasts for about 3-5 days if stored at or below 40 degrees Fahrenheit in the fridge according to the standards set by the USDA. It should be stored in air-tight containers or plastic zipper bags on one of the shelves of the refrigerator.
Cooked beef roast lasts for about 3-4 days when stored in an air-tight container in the fridge at or below 40 degrees Fahrenheit.
It is worth mentioning that the figures mentioned above are the estimated shelf life of prime rib.
What is the optimum temperature to store prime rib roast?
You should always store your prime rib roast at 40 degrees Fahrenheit or below. Bacterial growth takes place at a faster pace between the temperature of 40 and 140 degrees Fahrenheit, therefore it is always advised to store your prime rib at a lower temperature to preserve their freshness for a long time.
How long does prime rib roast keep at room temperature?
Prime rib roast lasts for about 2 hours when kept at room temperature.
You should discard the prime rib roast that has been left in open for more than 2 hours as bacterial growth takes place at a faster pace between the temperature of 40 and 140 degrees Fahrenheit, therefore there are greater chances of the prime rib roast being already contaminated with bacteria when left out for more than 2 hours.
Moreover, if the temperature of the surroundings is about 90 degrees Fahrenheit, then the process of spoilage takes place at a faster pace and it is recommended to discard prime rib roast that is left out in the open for more than an hour at 90 degrees Fahrenheit.
How long is prime rib roast good for in the freezer?
Raw prime rib roast, if kept wrapped in aluminum foil in an air-tight container or air-tight plastic freezer bag, can last for about 6-12 months in the freezer. On the other hand, cooked rib roast lasts for about 3-4 months when stored properly in the freezer.
Thus keeping the prime rib roast in the freezer will increase its shelf life considerably owing to the cool temperature of the freezer that halts the bacterial growth on the prime rib.
How long does prime rib roast last after being frozen and thawed?
Frozen prime rib roast if thawed in the refrigerator can stay there for 3-5 days before cooking it.
But if you thaw your prime rib roast in a bowl of cold water or the microwave, it is advised to cook it immediately till its internal temperature rises to 165 °F.

Different ways to spot bad prime rib
There are a couple of indicators that point out a bad prime rib. You should consider the appearance, texture, and smell of the prime rib to reach a final verdict on whether or not they have gone bad.
If you spot a mold or other organic growth on your cooked or uncooked prime rib roast then it means that your prime rib has gone bad and the best thing you can do in this scenario is to get rid of them.
It is worth mentioning that you should refrain from smelling prime rib that has molds on it as molds can produce mycotoxins that if they enter your body even via inhalation can disrupt your gut microflora thereby weakening your immune system.
If you notice that the prime rib has off colors (greenish-grey or brown) then it is an indication that your prime rib has gone bad and it is better to discard them.
Several factors can be responsible for a change in the color of the prime rib and that includes light, oxidation reactions, temperature, and bacterial contamination.
If you feel something slimy or gooey while touching the prime rib then it means that your prime rib has gone bad and it is better to discard them.
But keep one thing in mind that rinsing the prime rib won’t help you in this scenario as you won’t be able to get rid of the bacteria. Rinsing the bacteria-laden prime rib will put you at risk of cross-contamination as the bacteria will spread in the utensils and other food items that will come in contact with the water from the prime rib that has gone bad.
It is worth mentioning that you should wash your hands thoroughly after touching the bacteria-laden prime rib or else the bacteria will transfer from your hands to any other thing that comes in contact with your hands.
If you smell something sour or ammonia-like while taking a sniff test of your prime rib then it means that your prime rib has gone bad.
If microbes somehow found their way to your prime rib and have spoiled it then the best thing you should do is to discard it.
