Can raw lamb that has turned brown in the fridge still be used?

No, raw lamb that has turned brown in the fridge should not be used.

When meat turns brown, it is a sign that it is beginning to spoil. This is due to the oxidation of the myoglobin in the meat, which is a protein that gives meat its red color. As the meat ages, the myoglobin breaks down and the meat turns brown.

In addition to the change in color, spoiled meat can also have a sour or off smell, and it may be slimy to the touch. If you notice any of these signs, it is best to discard the meat.

Consuming spoiled meat can lead to food poisoning, which can cause symptoms such as nausea, vomiting, diarrhea, and abdominal pain. In some cases, food poisoning can be serious and even life-threatening.

Therefore, it is important to be aware of the signs of spoilage and to discard any meat that shows these signs.
