The Arizona Farm Bureau's latest Market Basket Survey shows retail food prices in the state are down about 1 percent in the 1st quarter of 2012.

The total cost of 16 basic grocery items is down $0.60 from the 4th quarter of last year to $50.79.

The survey shows grocery prices in Arizona are 6 percent higher than they were a year ago. The national survey, also released this week, reflected a similar increase.

Kevin Rogers, president of the Arizona Farm Bureau, says the Market Basket Survey is a valuable tool for consumers to measure the money they spend on food.

Rogers says the bureau sends shoppers out to grocery stores four times a year to measure prices of 16 basic foods. And they ignore sales and discounts, buying everything at full price to get a more accurate measure of food prices over time.
