For farmers and ranchers
The website states that Yonker Brothers Processing is a local source to harvest animals that customers raise, offering USDA certified domestic processing for beef, pork, sheep and goat. The federal record lists cattle, hogs, and sheep and lamb as species slaughtered under inspection, and the plant also reports custom-exempt slaughter, meaning customer-owned animals can be processed and returned in packages marked Not for Sale. Pricing and recipe options are posted on the domestic processing page, and an order form with cut sheet is available for download. Booking procedures, scheduling lead times, minimums, and hanging weight fees are not stated in the sources on file. FSIS places the plant in the lowest slaughter volume category, under 1,000 head per year.
Yonker Brothers Processing 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 business operates a retail meat market and an online shop, and reports retail-exempt sales to FSIS. Listed shop categories include meat market cuts, dried meats, ready to eat items, deli, seasonings, and merchandise, and the site says products are shipped straight to the customer's door. Deli orders include custom salads, sandwiches, and wraps, and the site invites phone calls at (325) 294-4844 to arrange specialty gifts, party trays of dried meats and cheeses, and sandwich platters for gatherings. Whether halves, quarters, or bulk bundles of beef or pork are sold is not stated in the sources on file.
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.
