Beef is one of the most commonly consumed meats It’s tasty, nutritious, and versatile enough to use in everything from burgers to stews However, like any perishable food, beef can spoil if not stored and handled properly. Eating spoiled beef poses potential health risks, including foodborne illness.
So how can you tell if the beef sitting in your fridge has gone bad? Here are 7 clear signs to check for when assessing the safety and freshness of beef:
1. Check the Smell
Your nose often provides the first indication that beef has spoiled. Fresh beef has a neutral or meaty smell. As beef starts to go bad, it gives off a potent, unpleasant odor that is immediately distinguishable from the smell of fresh beef.
Common descriptions of bad beef smell include:
- Putrid, rotten, or sour
- Ammonia-like or vinegary
- Unusually sweet or fruity (caused by microbial growth)
If you detect an off smell when opening a package of raw beef, it’s safest to discard it. Rely on your senses – if it smells funky, it’s likely gone bad.
2. Examine the Color
Fresh beef typically has a bright cherry red or purplish red hue. As beef ages and microbes proliferate, the meat loses its red pigmentation and turns brown or grey.
While some discoloration is normal, beef that has turned green, blue, or black has likely spoiled due to microbial growth. If you notice these unusual colors on raw beef, toss it out.
For cooked beef leftovers, look for fading from pink to a brown or grey color as an indicator of spoilage.
3. Check for Sliminess
Fresh beef has a moist, lean texture. As bacteria multiply, the beef develops a tacky or slimy feel and appearance.
Press your fingers gently into the surface of the raw beef. If a sticky residue clings to your fingers or it feels excessively moist, slimy, or sticky, the beef has probably spoiled and should be thrown away.
4. Be Wary of Mold Growth
The presence of mold on beef is a definitive sign it has gone bad and should not be eaten. Mold grows filaments that penetrate into the meat, well below the visible mold.
Even if you try to cut away the moldy sections, toxic mold residue likely remains in the beef. Discard beef immediately at the first sign of fuzzy mold growth.
5. Note Any Rancid Smell When Cooking
If you’re uncertain about the freshness of older beef, the cooking process can provide more clues.
Rancid beef gives off a clearly unpleasant, rotten odor when cooked. Usually, this rancid smell indicates spoilage. Cooked beef that smells bad is not worth tasting or eating – play it safe and throw it away.
6. Watch Out for Weird Textures
Along with sliminess, spoiled raw beef may feel unusually soft or mushy. Cooked beef that has gone bad can become dry, gritty, or mealy.
If you notice weird textures that are atypical for fresh, properly cooked beef, it’s best to be cautious and avoid eating it. The change in texture signals microbial decomposition and spoilage.
7. Check Expiration and Freeze Dates
Labeling offers useful guidance for assessing beef safety, although smell, touch, and sight should trump the label if there are signs of spoilage.
-
“Sell By” dates indicate the end of peak freshness – beef may still be used for several days past this date if properly stored.
-
“Use By/Best By” dates are better indicators for the limits of safe use; however, your nose knows best.
-
“Freeze By” dates should be heeded for raw beef that was previously frozen; frozen beef generally lasts 3-6 months if kept at 0°F or below.
While not foolproof, following the label guidelines in conjunction with looking for other signs of spoilage provides the best strategy for weeding out bad beef before you accidentally eat it.
How to Store Beef Safely
Proper storage helps beef stay fresh as long as possible and reduces the chances of accidental spoilage. Here are some tips for maximizing beef’s shelf life:
-
Keep raw beef refrigerated at 40°F or below. Freeze if not using within 2-3 days.
-
Separate raw beef from other foods in the fridge to avoid cross-contamination.
-
Wrap tightly in plastic wrap or place in sealed containers to block exposure to air and prevent drying out.
-
Cooked beef should be refrigerated in airtight containers within 2 hours; use within 3-4 days.
-
Either freeze beef for long-term storage or cook and freeze it if you won’t use it in time. Raw beef can be frozen for 4-12 months while cooked beef keeps for 2-3 months in the freezer.
-
Always thaw frozen beef safely in the fridge, never at room temperature. Cook immediately after thawing.
By storing beef properly and keeping a close eye on signs of spoilage, you can feel confident about serving beef to your family without worrying about foodborne illnesses. Trust your senses, follow expiration dates, and know the visual and aromatic signals that indicate it’s time to toss out bad beef. With these handy tips for spotting spoiled beef, you can keep your kitchen safe and waste-free.
Color: More Than Just a Fading Hue
The colour of beef is another important indicator of its freshness. When beef is fresh, it should be a vibrant red colour due to the exposure to oxygen. As it ages, the beef may turn brown or greyish, which can be normal, especially if it’s been vacuum-sealed. However, if the beef is significantly discoloured, such as turning a dull grey or greenish hue, it’s likely no longer safe to eat. Beef that has developed an unusual colour—particularly green or yellow—indicates that bacteria may be present, and you should discard it.
Expiration Date: Don’t Rely Solely on Dates
While the sell-by and use-by dates printed on beef packaging can give you a good indication of how long the meat is likely to stay fresh, they are not always foolproof. Beef that’s kept past these dates, especially if it hasn’t been stored correctly, is more likely to spoil. Always use your senses—smell, touch, and sight—along with the date on the packaging to make your final judgment.

What happens if beef goes bad?
Fresh beef is red. Beef has a pigment called oxymyoglobin that can become red in the presence of oxygen. As beef goes bad, more of this pigment will be consumed by bacteria, and soon, the steak will lose its pigmentation. Bad beef changes color from red to brown or gray according to the temperature, pH, light, and other external factors. 5.
