The USDA has just raised its expected food inflation numbers to 6% for 2008 on the heels of a 4.2% increase for 2007.

My best guess is that they will be back to the well to up that again by the end of the summer. The projections show the greatest increase in food prepared at home with eggs, dairy and fats and oils categories leading the charge. Pork is estimated to increase only 1-2 percent this year.
