A worker waits for olives to be crushed at a traditional olive oil processing factory in the eastern village of Al Kalaa, near Bejaia, about 250 km (155 miles) from Algiers, February 6, 2010. Farmers said the dip in this year's olive oil production was due to unusual weather patterns during the flowering season that had reduced the oil content in the olives. It was also attributed to some olive growers not respecting cultural techniques in the cultivation of olive oil, which led to damage in the new growth during the harvest season.
