Sausage discolouration - is it safe to eat?
This morning, I found some sausages in the fridge that had been there all week. The top of the sausage (that is, the surface of the skin facing upwards) had turned brown. I initially thought that if I just fried them long enough, this would be fine; however, while frying I did a quick search on the web, got spooked and threw them away.
My question is: what causes this discolouration and, have I needlessly thrown three very tasty looking sausages in the bin?

My question is: what causes this discolouration
Many meats are dyed to make them look fresher. They add red, cause meat is red right? Well no. Most meat will "brown" or "gray" as it is exposed to the air and the blood dries up (or drains out). This is not, in any way, a sign of bad meat. In fact it "may" be a sign of good, natural meat.

and, have I needlessly thrown three very tasty looking sausages in the bin?
Yes, probably.
Important note
When in doubt throw it out. A week in the fridge (not freezer) is border line for me. I would have probably cooked it, but I wouldn't fault someone else for not cooking it.
You can usually look for smell or slime to tell if meat is bad.

Is discolored sausage safe to eat?
Note that the sausage is still in good condition and perfectly fine to eat. However, if the ground breakfast sausage displays a gray or brown discoloration on the outer surface of the meat, the breakfast sausage is starting to spoil, and it's best to stay safe and discard it.How can you tell if raw sausage is bad?
First, if your pork sausage has gone bad, you can tell by the sausage's smell, look, and texture. If it has a putrid odor, a slimy coat, or a uniform color, then you shouldn't eat it.Can you eat oxidized sausage?
Oxidation is a natural process that happens to various types of food, but it doesn't make the food bad. For example, when you leave your apple on the kitchen counter, you will notice that it has become browner after a few minutes. However, it's still edible. The same applies to sausages.Can you eat GREY sausages?
Well no. Most meat will "brown" or "gray" as it is exposed to the air and the blood dries up (or drains out). This is not, in any way, a sign of bad meat.This is why sausages can cause cancer

Answer 2
The one on top was probably exposed to air and its surface dried out which darkened it.
It's always better to be safe than sorry. I am a little more edgy and eat things others don't, but I have my limits of acceptable also. I wouldn't eat something a week old unless I was sure it was packed and stored properly.
Answer 3
The discoloring isn't a problem: it's just the meat reacting with oxygen in the air. The same thing would happen, only more slowly, if you'd frozen the sausages.
The problem is possible bacterial growth. By the time the bacteria levels become high enough to be visible, it's far past the point where the bacteria are dangerous. Further, many bacterial excrete toxic substances that aren't inactivated by cooking. This is why you should usually go with expiration dates rather than "what it looks like" to determine if food is safe to eat. (There are some exceptions, where either spoilage is visible or it simply doesn't spoil at all, but sausage isn't one of them.)
Answer 4
The brown colour is because haemoglobin in blood oxidises in air (like rust forming on iron), but this is distinct from changes caused by bacteria that leads to food poisoning.
