(AREA) -- The total bill for a typical Independence Day picnic edged up slightly this year, but still tallies less than $6 per person, according to a recent survey by the American Farm Bureau Federation. The national farm group's annual marketbasket survey leading up to the calendar's most American holiday found a menu of summertime favorites is approximately five percent more expensive than a year ago. 84 volunteer shoppers in 25 states checked retail prices for summer picnic foods at their local grocery stores for this informal survey. Their shopping list included hot dogs and buns, cheeseburgers and buns, pork spare ribs, deli potato salad, baked beans, corn chips, lemonade, chocolate milk, watermelon, and ketchup and mustard. They found that the average cost of that summer picnic for 10 is approximately $58.72, or $5.87 per person. The survey is part of Farm Bureau's quarterly marketbasket series, which also includes Thanksgiving and two "everyday" surveys of staple food products used to prepare meals in typical Americans homes.
