Biohazard and Pathogen Disinfection in Middleburg, PA

Middleburg is a borough in Snyder County and serves as the county seat, even though nearby Selinsgrove is the county's largest borough.

Middleburg was originally named Swinefordstown, in Pennsylvania Dutch dialect Swinefordstettle, after John Albright Swineford, who ran a tavern there in 1787.

Engineer Frederick Evans laid out Middleburg in 1800 on Swineford's land along the north bank of Middle Creek, and the town became known as Middleburgh around 1825 before being incorporated as a borough in 1864.

When Snyder County was created from part of Union County on March 2, 1855, Middleburg was chosen as its seat; the county honors Simon Snyder, Pennsylvania's governor from 1808 to 1817.

Middleburg is home to the main processing plant of Ira Middleswarth and Son, the maker of Middleswarth Potato Chips, a regional snack-food institution.

The Middleburg Tannery, a major postwar employer that tanned sole leather used in Florsheim shoes, was destroyed by a devastating fire in June 1967 and never rebuilt.

Although the Swineford side of town was annexed into Middleburg in 1917, the borough kept two separate post offices until March 1955, and the Swineford name survives in the Swineford National Bank, founded in 1903.

Middleburg had a population of 1,325 at the 2020 census, and at the 2000 census it had 611 households in about 0.9 square miles.

The Snyder County Times, one of the region's regular newspapers, is headquartered in Middleburg.

Part of present-day Middleburg was the site of the Stump's Run Massacre of January 1768, a notorious frontier incident in which two colonists killed ten Native Americans and escaped trial after a mob freed them from jail.
