WHO estimates that 1.5 million people died from diarrheal diseases in 2012, which comprises about 2.7 percent of deaths. Fortunately, thatâs down from 2.2 million in 2000. Diarrheal disease is the second top killer of children under age five. Tragically, about 760,000 children die from diarrheal diseases each year.
1 After 20 minutes turn the oven down to 325 degrees F. and roast until the desired internal temperature is reached (see guide below). 2  For medium-rare this will take approximately 15 minutes per pound. 3  Transfer to a large platter, and let the prime rib rest, loosely covered with foil for 30 minutes before serving. When the oven is hot, put the roast in and cook for 20 minutes to sear the outside of the roast. 2  After 20 minutes turn the oven down to 325 degrees F. and roast until the desired internal temperature is reached (see guide below). 3  For medium-rare this will take approximately 15 minutes per pound.
1 --------------------------------------------. APPROXIMATE COOKING TIMES for the prime rib cooked at 350Â°F after the 20 minute cooking time at 450Â°F. 2  Rare; cook 12-13 minutes per pound or to 130Â°F. Rare; cook 12-13 minutes per pound or to 130Â°F. 2  Medium-rare; cook 14-16 minutes per pound or to 140Â°F (I would not recommend cooking a prime rib any more than medium-rare). 3  Since every oven cooks differently cooking times are only approximate.
