Almost 1 in 3: The chance that the hot dogs and pork sausages consumed on the Fourth of July originated in Iowa. The Hawkeye State was home to 19.7 million hogs and pigs on March 1, 2012. This estimate represents almost one-third of the nation's estimated total. North Carolina (8.6 million) and Minnesota (7.6 million) were also homes to large numbers of pigs. Source: USDA National Agricultural Statistics Service

7.2 billion pounds: Total production of cattle and calves in Texas in 2011. Chances are good that the beef hot dogs, steaks and burgers on your backyard grill came from the Lone Star State, which accounted for about one-sixth of the nation's total production. And if the beef did not come from Texas, it very well may have come from Nebraska (4.6 billion pounds) or Kansas (4.0 billion pounds). Source: USDA National Agricultural Statistics Service

6: Number of states in which the value of broiler chicken production was estimated at $1 billion or greater between December 2010 and November 2011. There is a good chance that one of these states — Georgia, Arkansas, North Carolina, Alabama, Mississippi or Texas — is the source of your barbecued chicken. Source: USDA National Agricultural Statistics Service 

Please Pass the Potato: Potato salad and potato chips are popular food items at Fourth of July barbecues. Approximately half of the nation's spuds were produced in Idaho or Washington state in 2011. Source: USDA National Agricultural Statistics Service
