U.S. Department of Agriculture A package of hot dogs that contained glass shards, according to a federal food inspector.

If you’re stuck in town this Labor Day weekend without so much as a roof to grill on, wipe that hangdog look off your face: Maggots, worms, metal, plastic and even a razor were just a few of the objects that horrified callers said were in their hot dogs in complaints lodged with the U.S. Department of Agriculture between 2007 and 2009.

Back in 2009, this reporter filed a Freedom of Information Act request asking the U.S.D.A. to give up its dirty-dog logs. The 64 case files finally came in this week, just in time for the holiday! Consider them food for thought if you’re planning to grill during these last dog days of summer.

The documents (viewable here) tell numerous cringe-inducing tales of foreign objects disrupting all-American meals. Band-Aids, a rubber glove, and even a lock washer (used to secure a bolt) are all described in snappy detail.

One report told of a “winged insect that resembled a dragonfly inside the package of hot dogs,” and noted that the insect’s “head, eyes, and wings are visible. Insect is black in color, over 1-inch long.”

In the vast majority of cases, U.S.D.A. investigators determined that the gross-out did not indicate a pattern of neglect at the packing plant, and simply notified the company that handled the hot dog.

But on at least one occasion, even the federal officials in charge of inspecting food became the subjects of an investigation. As one document from June 13, 2008 reveals, a Food Safety Inspection Service employee bit into a rogue hot dog at an “F.S.I.S. Unity Day” cookout in Maryland.

U.S.D.A. Shards of glass from a hot dog purchased in Nebraska.

According to the report, the employee “looked down into the hot dog and saw a soft piece of plastic like the type they use for bread, thin plastic. Looked circular, maybe about 14-and-a-half inches in diameter with a line of black ink, printing on the plastic. No injury noted.”

The Local thought this was a real man-bites-dog story, but a spokesman for the Hot Dog and Sausage Council, speaking frankly about the matter, said foreign objects in hot dogs were a very rare occurrence, especially given the roughly 20 billion wieners made every year. According to the Council, between Memorial Day and Labor Day — known as “hot dog season” within the industry — roughly 818 hot dogs are consumed every second.
