About Underground Slaughter LLC

Underground Slaughter LLC, doing business as Underground Processing, operates at 6821 Franks Ferry Road in Walling, White County, Tennessee. The plant holds establishment numbers M51351 and P51351 and is listed with FSIS for meat processing, meat slaughter, poultry processing and poultry slaughter. FSIS classifies it as very small, with a grant of inspection date on file of July 14, 2021. Species slaughtered under inspection as reported to FSIS are hogs, sheep and lamb, and poultry, and the plant reports custom-exempt slaughter, meaning animals owned by the customer are processed and packaged marked Not for Sale.

The company website states the business was established in 2017 by Larry Masters in a facility originally built as NIKO & COMPANY, and that it opened to the public in June 2018 after receiving a USDA grant of inspection. The federal record shows a grant date of 2021-07-14, so the two dates differ. The website describes the plant as the first and only small farm poultry processing facility in Tennessee under USDA inspection and says it serves small farmers in Tennessee and the Southeastern United States. Published service pages cover pork, poultry, lamb and sheep, rabbit, goat, curing and smoking, marinades, and sausages.

Published price sheets list both custom and USDA processing fees for pork and per-bird fees for poultry, along with charges for grinding, sausage seasoning, links and patties, offal, lard rendering, curing, smoking and slicing. Retail sales, storefront hours, ownership beyond the founder named on the website, and any religious or third-party certifications are not stated in the sources on file.

Underground Slaughter LLC reports custom-exempt slaughter to FSIS, which means it can process an animal a customer already owns (a whole, half, or share bought before slaughter) and return it in packages marked Not for Sale. Most small farms have one or two plants they book with, and the plant's calendar decides the delivery date.

For households

The sources describe a processing facility serving farmers and small producers and do not state that a retail counter, halves and quarters for sale, bundles, delivery, shipping or online ordering are offered. Households interested in buying meat directly should contact the plant, as retail availability is not stated in the sources on file. Note that product from custom-exempt slaughter is marked Not for Sale and may not be resold.

If you are buying a half or quarter animal, the plant is where the animal is processed; the farm sells you the animal. Read how to buy a half cow for the sequence and the math.
