How to Know if Ground Beef is Bad to Consume?

How to tell whether ground beef is hazardous for you: Ground beef is a popular addition to many people’s diets because of its flexibility. Despite this, it is more prone than other meats to spoiling and being contaminated, resulting in illness. When selecting ground beef, it’s important to evaluate the color, texture, scent, and expiration date, among other factors.

The general populace in the United States likes ground beef. The Trusted Source brand accounts for 62 percent of all ground beef sold in the United States, according to study findings. The grinding method, on the other hand, increases the surface area of the ground beef, making it more sensitive to bacteria that might be harmful. Aside from that, because of its shorter shelf life, this cut of beef is more susceptible to spoiling than other cuts of cattle.

There are two kinds of bacteria that may be harmful to ground beef: spoilage bacteria and pathogenic bacteria. The bacteria that cause food spoiling are not usually harmful, but they do lower the nutritional content of the food item they are infected with. This might result in an unpleasant odor or taste. Pathogenic bacteria are more dangerous than nonpathogenic germs. In the case of foodborne disease, the source of which was contaminated, the resultant food poisoning might be caused by them.

This article will discuss numerous methods for determining if ground beef has gone bad, including some of the most common ones.

How to Know If Ground Beef is Bad?

It is possible to fall ill after consuming undercooked or rotting meat. As a result, proper handling, storage, and preparation of meat are critical in order to prevent this. Additionally, there are a number of signs that ground beef has gone bad that consumers should be on the lookout for.


The color of the ground beef may help you determine if it is safe to eat or whether it has gone bad rapidly. When purchasing fresh ground beef from the supermarket, look for a rich red exterior to suggest great quality and the absence of deterioration on the inside.

The reaction between oxygen in the air and oxymyoglobin, a meat pigment, results in vivid red color on the surface of the meat. Oxymyoglobin, the red liquid that oozes from cattle, is occasionally mistaken for blood, according to some.

Nonetheless, since there has been no interaction with oxygen, the meat’s inside may appear greyish brown; however, the meat is still safe to eat.

If the outside of the ground beef gets grey or brown, it should be thrown out immediately. If it’s beginning to discolor, it means it’s going to go bad.

If there is visible mold on the surface of the ground beef, it should never be consumed. Raw ground beef and cooked ground beef are both included in this category.


Another technique to identify whether meat is rotting is to examine the texture of the piece of flesh. A safe piece of ground beef should be hard enough to hold together when pressed yet soft enough to break apart easily.

If the texture, on the other hand, is sticky or slimy, it might indicate the presence of decaying germs. A bacterial infection that produces ropy slime might be the source of this problem. If these bacteria emit volatile compounds onto the surface of the meat, slime may form on the surface of the meat.

Individuals should thoroughly wash their hands after handling raw meat in order to avoid the transmission of germs to others.


It is also possible to smell ground beef to detect if it is bad. If the fresh ground beef is normal, safe, and nutritious, it should not have an overpowering stench. The development of decaying microbes, on the other hand, may result in unpleasant smells.

Pathogenic bacteria, on the other hand, aren’t necessarily to blame for a foul odor in the environment. When ground beef does not smell nasty but exhibits other signs of rotting, it is still advisable to discard the meat.

The date on which the license is set to expire

Aside from infant formula, the Food and Drug Administration (FDA) does not require the insertion of an expiration date on food packaging. However, according to regional rules, the majority of food goods are labeled with an expiration date.

The FDA prefers to use the phrase “best if used by” rather than the phrase “best before” in order to minimize misunderstanding, according to the source. Labels such as “best before” indicate how long the item is anticipated to retain its quality and flavor, not how long it is expected to be safe to consume.

Keep in mind that you don’t always have to throw out meat products that are beyond their “best before” date if you store them properly and safelyTrusted Source. Ground beef that has been refrigerated may be consumed for up to two days after this date. It is recommended that ground beef be eaten within four months after being frozen.

Side Effects of Eating Spoiled Ground Beef

Ground beef is used in a variety of cuisines, including sauces, hamburger patties, and pasta dishes. It has become ubiquitous in the United States, thanks to fast food burgers and small establishments that provide meatloaf and casserole dishes. Ground beef should be cooked or frozen within two days after purchase, according to the USDA, in order to maintain its nutritional value and quality. Ribeye beef that is slippery or sticky, or that has an unpleasant odor, is almost certainly rotting.

Bacteria that are contagious

As a result of the higher amount of surface area exposed to the air that ground beef has compared to a solid piece of meat, it is more prone to microbial development. When beef degrades as a result of insufficient or non-existent refrigeration, pathogenic bacteria may develop. Staph aureus, Campylobacter jejuni, and Escherichia coli O157:H7 are odorless and cannot be seen, but they thrive at low temperatures and cause food poisoning in humans; their odor cannot be distinguished from other bacteria that cause food poisoning in humans. Food poisoning, which causes diarrhea and vomiting, affects as many as 81 million Americans each year, according to some estimates.

Microorganisms that are beneficial in the degradation of food waste

Keeping meat refrigerated or frozen for a lengthy amount of time may cause germs to grow on it. Food should be stored in refrigerators at temperatures of 40 degrees Fahrenheit or below to ensure maximum freshness. Listeria monocytogenes, a bacterium present in naturally spoiled meat, is suspected of causing a number of illnesses that manifest themselves as flu-like symptoms. Bacteria detected in food waste have been linked to meningitis, encephalitis, and septicemia, among other illnesses. As a consequence of this, pregnant women may develop intrauterine or cervical infections.


Spoilage bacteria may seem to cause no symptoms in healthy individuals, but cancer patients and the elderly are especially susceptible when it comes to infection. Women who are pregnant or under the age of 30 are also in danger. Listeria monocytogenes account for about 70% of all listeria-related deaths in the United States, with less than 500 deaths per year attributable to active infections.

How to Store Beef Safely?

Any person who is worried about developing a disease from contaminated food should take the following four measures, according to the Food Safety and Inspection Service of the United States Department of Agriculture:

Maintain cleanliness by washing hands thoroughly and wiping off surfaces on a regular basis.

Maintaining a separation between raw meat and other components is important when preparing and storing meals.

Food should be prepared correctly, at a suitable temperature, and at the appropriate time. Cook

Remove from heat and immediately refrigerate or freeze food at the appropriate temperature.

People should make certain that the temperatures in their refrigerator and freezer are at the proper levels in order to keep their food safe. Refrigerators and freezers should be maintained at or below 40°F (4°C) and 0°F (-17°C), according to manufacturer recommendations.

Meatballs may be stored in the refrigerator for 1–2 days and should be consumed within 4 days if kept chilled. Ground beef may be stored in the freezer for up to four months at a time.

In order to properly cook ground beef, a food thermometer set to 160°F (71°C) should be used. Never leave ground beef out at room temperature for more than two hours at a time, since this may stimulate the development of harmful microorganisms that may be harmful to your health.

Grounded beef may be kept fresh for a longer period of time provided it is handled and stored properly. People must, however, be aware of the signs and symptoms of spoilage, which include changes in color, smell, texture, and damage to the packaging or storage.

The appropriate handling and storage of ground beef are essential, but it is also essential that it be cooked properly to destroy bacteria at the right internal temperature.
