http://en.wikipedia.org/wiki/Agflation

Agflation, a term coined in the late 2000s, describes generalised inflation led by rises in Agricultural commodity prices. In the United States, agricultural prices are not generally factored into core inflation figures. The term describes a situation in which "external" (ie Agricultural) price rises drive up core inflation rates.
