Why does Hamburger turn brown when it's going bad?

Hamburger turning brown does not necessarily mean "it's going bad". What is happening is that the iron in the meat is oxidizing. That may or may not mean that spoilage is occurring. Obviously, one needs to use good judgment regarding its "freshness" vs. "spoilage".

Vince Calder

You might notice that hamburger turns brown when you cook it. Obviously, that does not mean it is going bad. Meat will turn brown before it is actaully "bad from bacterial action". Smelling the meat is a good way of determining freshness.

However, when in doubt, do not eat.
