CALDERON FREEZES PRICES ON 24 PROCESSED FOODS   In the face of rapidly rising food prices worldwide, the Calderon administration froze retail prices on 24 processed items through the end of 2008. Included in the list are premium tuna, sardines, preserved peaches, three kinds of spaghetti sauce, strawberry jam, flan, canned beans, selected fruit drinks, instant coffee, catsup, prepared jello, shrimp soup, dehydrated parsley, garlic salt, and two kinds of pepper. Not included in the list are tortillas, cooking oil, corn, rice, sugar, powdered milk, wheat flour, bread, meat, eggs, cheese or vegetables. The Confederacion de Camaras Industriales (Concamin), a leading business organization, approved the measure.
