Knowing how long raw beef can sit at room temperature is key to avoiding foodborne illnesses. While fresh beef is perishable and harbors bacteria, proper handling and storage can maximize its safety and quality This article provides a comprehensive guide on the time limits for leaving raw beef out and related food safety practices.
How Long Can Raw Beef Sit Out Unrefrigerated?
According to food safety experts, raw beef should not be left out unrefrigerated for more than 2 hours, whether at room temperature or above 90°F This is known as the “2 hour rule” for meats.
The 2 hour timeframe applies to all types of raw beef – ground beef, whole cuts like steaks and roasts, and stew meat. It also applies whether the meat is in a package or placed in a container.
Why You Shouldn’t Exceed the 2 Hour Limit
Raw beef naturally contains bacteria which are killed during proper cooking. When left between 40°F and 140°F, the “danger zone” temperature range, bacteria can rapidly multiply and pose a safety risk.
Common foodborne pathogens found in raw beef include Salmonella, Escherichia coli O157:H7, Campylobacter, and Listeria. Given the ideal conditions, these bacteria can double in as little as 20 minutes.
Consuming beef left out too long can cause symptoms like diarrhea, vomiting, and abdominal cramps. In severe cases it may even lead to kidney failure or death. Adhering to the 2 hour rule prevents foodborne disease.
What If Raw Beef is Left Out Overnight?
Raw beef left on the counter or at room temperature overnight has certainly surpassed the 2 hour mark.
According to food safety experts, consuming such meat poses a high risk of food poisoning and should be discarded. The bacteria present likely multiplied to dangerous levels.
While cooking the beef thoroughly may kill the bacteria themselves, toxins produced by the microbes can withstand high cooking temperatures. For maximum safety, leftovers should also be refrigerated within 2 hours.
Proper Storage Temperatures for Raw Beef
To inhibit bacteria growth, raw beef should be stored:
- At 40°F or below in the refrigerator
- At 0°F or below in the freezer
Ground beef may be refrigerated for 1-2 days while steaks and roasts can typically last 3-5 days. For freezer storage, ground beef keeps 3-4 months while other cuts remain safe for 4-12 months.
These time limits for beef storage in the fridge and freezer prevent spoilage and maintain quality. Use vacuum sealed packages or plastic wrap to prevent freezer burn.
Marinades Don’t Make Raw Beef Safe
While marinades like vinegar and lemon juice have antimicrobial properties, they do not make raw beef safe to leave out for prolonged periods. The 2 hour rule still applies even when marinating raw beef.
Certain spices like oregano also have some bacteria-fighting capabilities. However, they cannot prevent pathogen growth in meat left more than 2 hours unrefrigerated. It is better to play it safe and discard such beef.
Thawing Frozen Raw Beef
Never thaw frozen beef on the counter. The outer surface could enter the danger zone temperature range and harbor rapid bacteria growth.
The safest thawing methods are:
- In the refrigerator – 24-48 hours for cuts
- In cold water – 30 minutes per pound changed every 30 minutes
- In the microwave – if cooking immediately after thawing
It is safe to cook beef immediately from frozen state. But thawed meat cooks more evenly. Always cook or refreeze thawed beef within 1-2 days.
Is Rare Beef Safe to Eat?
Rare and medium-rare beef is safe to eat provided it has reached the proper internal temperature during cooking.
- Rare beef should reach an internal temperature of at least 145°F.
- Medium-rare beef should reach an internal temperature of at least 160°F.
Ground beef should always be cooked to 160°F since pathogens could be spread throughout during processing.
Using a meat thermometer ensures beef reaches safe internal temperatures to destroy any bacteria present. Let meat rest 3 minutes before carving.
Key Takeaways on Leaving Beef Out
To summarize, follow these food safety practices regarding raw beef:
- Never leave raw beef out for over 2 hours before cooking or refrigerating
- Cook or freeze beef within 1-2 days of thawing
- Refrigerate cooked beef leftovers within 2 hours
- Verify safe cooking temperatures with a meat thermometer
- Store beef properly chilled at 40°F or below
Following the recommendations for time limits, cooking temperatures, and refrigeration will keep beef safe. When in doubt, remember the motto: “When in doubt, throw it out!”
What Is the Best Way to Package Meat For Freezing?
The most important thing to keep in mind when packaging meat for the freezer is that air is the enemy. You want as little air in your packaging as possible, because that’s what ultimately causes freezer burn!
If your meat comes in a vacuum-sealed package, you can successfully freeze it as-is. Styrofoam trays aren’t as airtight, so you can either over-wrap them in tight plastic wrap or repackage their contents by wrapping them in plastic and placing them inside a freezer bag.
Previously cooked meat can also be frozen in a freezer bag or a freezer-safe container. Make sure to squeeze out as much air as possible before you zip it up, and label what is cooked and what is fresh. Ground meat in particular can be hard to identify between raw and cooked after it’s frozen.
When you put your packages in the freezer, you want them to freeze as quickly as possible to prevent the growth of ice crystals which will damage the texture. Lay the items flat and don’t stack them until they’re solid. Ideally, you would freeze your meat in a stand-alone freezer that isn’t opened often. The more often you open your freezer, the more likely you are to lose temperature.
Does Frozen Meat “Go Bad?”
According to the USDA, frozen meat kept at 0°F or lower will always technically be safe to eat. This low temperature prevents the growth of microorganisms and microbes like bacteria and mold.
But that doesn’t mean it will taste good forever. While freezer burn doesn’t make frozen meat unsafe, it will make the texture dry and leathery. According to Nourish by WebMD, to identify freezer burn, look for ice crystals on the surface of the meat, or for a shriveled or discolored appearance.
You can cut off freezer-burned spots before or after cooking. Or if the meat is heavily freezer-burned, you may want to throw it away entirely.
