According to the World Bank, internationally traded food prices increased by a sharp 4.0 percent. The leap was led by wheat and maize, up 18 percent and 12 percent, respectively.
As a result, international food prices in April were only 2.0 percent lower than a year ago and 16 percent below their record level in August 2012, the bank's quarterly food price report said.
"Increasing weather concerns and import demand -- and, arguably, to a lesser extent, uncertainty associated with the Ukraine situation -- explain most of the price increases," the report said.
World Bank economists said prices increased despite bumper crops in 2013 and continued projections of record grain harvests and stronger stocks expected for 2014.
