Is eating uncooked spaghetti dangerous

Of course you can store them in the fridge. When things start to smell bad, you should toss it. From what I remember off hand, every pancake or cornbread batter recipe I've read says about a week is safe.

If you need the eggs raw, you could submerge them in boiling water for 5 sec. That would kill any bacteria on the shell and the egg would still be raw inside. Put the eggs in cold water right away to prevent the egg from heating up by the residual heat in the shell. I have tried this many times and the eggs do not cook. If you are serving the eggs to very young children, pregnant women or someone who are sick, you should buy pasteurized eggs instead. But normally it's safer to eat eggs from chickens you raise, than the ones from a factory, because they are more healthy and their immune system is well developed enough to kill the salmonella itself.
