about one week is what most people will tell you , however i brought some a few years ago an kept them in my work van and ate on them for over 3 weeks. i did not get sick ,. if they start smelling or become slimey, throw them as far as you can out the window or simple put them in the garbage. i myself prefer throwing-them , it gives me a chance to vent all the bent up anger as i slange the peanuts like a Baseball pitcher who has rabies...
it can stay fresh for 2 weeks
Forever
It will stay fresh for some hours. Not too long. So it depends how long the fridge been off. Too long is bad.
cod will stay fresh forever if you freeze it in a air tight bag.
i would say brownies stay fresh for about 3-5 days if they are in a sealed container.
Weed stays fresh for a long time. You can put it in a plastic bag to keep it fresh for a long time or you can also freeze it.
Three days for cooked roast potatoes or cooked chips.
