Inflation at the wholesale level jumped in April by the largest amount in three months, fueled by rising prices of food and energy.

The Labor Department says its producer price index, which measures inflation before it reaches the consumer, rose 0.5 percent in April. That is a sharp rebound following a 0.1 percent decline in March. It was the largest gain since similar 0.5 percent rise in January.
