What causes dark cutting beef?
Dark cutting beef (DCB) is largely linked with stress and the mobilisation of muscle glycogen—energy store—in the live animal prior to slaughter.
This reaction converts glycogen into lactic acid.
This lactic acid causes the meat pH to decline from the neutral value of 7.2 found in the live animal..
Can you leave meat in the fridge for a week?
Most uncooked meat, regardless of cut, can be stored in the fridge for three to five days. But there are definitely exceptions. Ground meat and offal like liver and kidneys should only be kept in the fridge for one to two days.

All that ground beef underneath the top layer has no access to oxygen, so it turns an unappealing color of gray. This will also happen to any beef you store in the freezer. It’s perfectly safe to eat, although you should be aware that the color indicates it has been in the package for a while.

Why does my steak smell like cheese?
Steak Smells Like Cheese You may also notice that steak smells a bit like cheese when it’s cooking. This happens primarily to dry-aged steaks from the produced lactic acid that results from the dry-aging process. This can cause a taste and smell that is similar to blue cheese.
Why is my beef dark red?
A normal level of lactic acid (pH of 5.6) in the muscle will cause the meat to be bright cherry-red in color when it is exposed to oxygen for a short time period. In “dark cutting beef,” the animal undergoes long-term stress before slaughter. … “Dark cutting beef” occurs in 1 to 2% of beef carcasses.
Is brown red meat still good?
Answer: The steaks should be fine. As the U.S. Department of Agriculture points out, it’s normal for fresh meat to change color during refrigerator storage. For instance, it’s common for beef to turn more of a brownish shade, due to oxidation.
What happens if you eat bad beef?

Why did my steak turn GREY in the fridge?
This is the color of a freshly butchered piece of meat. But when myoglobin gets exposed to oxygen, it turns into a compound called oxymyoglobin. … The presence of oxygen, however, eventually turns beef grayish-brown. Myoglobin’s chemical compound contains iron, which, after a few days of oxygen exposure, will oxidize.
Why did my beef turn brown?
As meat ages it turns brown from oxidation. The oxidation process is a result of the bound iron molecule in myoglobin going from the ferrous to ferric form. This produces what is called metmyoglobin. Metmyoglobin is the cause of the characteristic brown coloration of meat that occurs as it ages.
Why is the inside of my raw steak Brown?
The iron molecule in the middle is oxidized from its ferrous to ferric form and a different complex is formed called metmyoglobin. This compound turns the raw meat a brown color. The meat is usually still safe to eat when cooked, but the brown, unappealing color turns off most consumers.
Is Dark beef bad?
A beef roast has darkened in the refrigerator, is it safe? Yes, it is safe. The darkening is due to oxidation, the chemical changes in myoglobin due to the oxygen content. This is a normal change during refrigerator storage.
Is dark red meat bad?
The good news is, even if there’s a color change — which might not be as visually appetizing — the meat or poultry is still perfectly fine to eat if stored properly in the refrigerator or freezer and consumed within a safe period of time (up to two days for ground meat and five days for other cuts).

Color – Rotten meats will also undergo a slight change in color. Poultry should be anywhere from a bluish-white to yellow in color.
Why is supermarket meat so red?
Fresh meat in the supermarket is red because of the pigment called “myoglobin,” which stores oxygen in muscle cells. … But the red color of freshly cut meat is temporary since aging, cooking, and bacteria, all separate the oxygen from the myoglobin, turning the meat a brownish-gray color.
