The Isle of Wight County Museum in Smithfield, Virginia is celebrating its most prized artifact, a slab of ham that is about to turn 112 years old. Museum curator Tracey Neikirk tells The Wall Street Journal that despite the fact the smoked meat is more than a century old, it's still edible. The museum will celebrate the ham's momentous birthday on Saturday, said Henrietta Gwaltney, granddaughter of P.D. Gwaltney Jr., the ham's former owner. "From a microbiological standpoint, it's got an indefinite shelf life once you remove enough of the water," said Dr. Randy Worobo, a professor of food microbiology at Cornell University. As for the taste, however, "it may not be acceptable," the scientist added.
