(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.
Infused oils last about 1 month when stored properly.  Allow flavored oils to sit out at room temperature for approximately 20 minutes before each use.  Don't use flavored oils for deep-fryingâleftover particles will burn.  When gifting flavored oils, include storage instructions as well as serving suggestions.
