(AP) -- Phil DeVore pulls a folded piece of aluminum from a murky pond. The aluminum looks like a piece of siding that's blown off a building, but DeVore knows it's much more valuable than that. He slips a rubber band off the aluminum and unfolds it. He likes what he sees -- 50 or 60 glistening black leeches. They're your common ribbon leeches, Nephelopsis obscura to aquatic biologists.
Storing Used Oil. Used oil can be successfully stored in a cool, dark place for up to a month. Refrigeration or freezing increases the oilâs lifespan by several months. The oil may become cloudy during storage but this is not harmful and the oil will become clear upon reheating.
As Time Goes By. Dry flours contain natural oils, which can go rancid over an extended period, only store well for six to eight months. Dried fruits still contain some moisture, so they only retain their quality for about six months, while vegetables, which dry completely, store well for up to a year. Plan to use the food within six months if you are unsure of the exact storage length recommendations of a specific item.
