I'm just jumping down to the dialog box after reading your first post and going to suggest that you dump it all and start fresh. Why put yourself through wondering "is this still good if it tastes like this?" Why eat rancid food when you can go buy fresh? Are we talking huge quantities of anything here? And even then, if you have lots and it's going to last a lot longer, it's going to be REALLY old by the time you finish. Fresh tastes best.

Even though things like white flour say they have a long shelf life, they are better when used soon after it is ground. If you're going to bother to cook, cook with fresh ingredients.

Test yourself--cook up something with that brown rice. Do you find yourself taking tentative bites, and not quite happy with it? I find if I've fixed something that I thought was a little old that I might eat some of it the first night, but I always have second thoughts and the rest is thrown out. If you can happily eat old food even if you wonder about it, you have the constitution of a goat (or my dog, who seems to be the compost gourmande) and it's a crap shoot. But me, I wouldn't fool with it. It would all go out in the compost with a bunch of dirt shoveled over the top, and run the sprinkler on it for a while. It'll be better when it comes back as next summer's tomatoes.
