Pena said the U.S. Department of Agriculture recently forecasted the consumer-price index for food will rise between 0.5 percent and 1.5 percent this year and between 2 percent to 3 percent for 2011.

“From 1990 to 2006 the average annual food price increase was 4 percent and the increase in 2010 will be the smallest since 1992,” he said. “While prices for basic commodities like corn and wheat are higher than they were in 2007, they remain well below the record highs of 2008.”

Pena said adverse weather, a weaker U.S. dollar, increased exports, higher crude-oil prices and heavy commodity contract buying by speculative investor funds have contributed to increasing commodity prices.

“Although the agricultural producer is sometimes vilified because of the increasing price of agricultural commodities, the lion’s share of that increase is due to factors beyond the producer’s control,” he said. “USDA data show farmers get less than 20 cents of every dollar spent on food. So the majority of the increase comes from the elevation of production and post-production costs, including the costs of energy, labor, advertising, packaging and transportation.”

He added, however, that producers do receive a higher percentage for foods consumed closer to their raw form, such as fresh fruits and vegetables, as opposed to processed food items, such as baked goods and cereal products.

“Still, on average, a 50-percent increase in the price received by the farmer results in only a 10- percent increase in the retail cost of food,” Pena said. “The recent upward movement in commodities pricing is expected to have little immediate effect on the prices of basic food items.”
