Poultry CAFOs and Livestock Operations in McDonald County

Why McDonald County is a poultry-industry county

McDonald County, in Missouri's far southwestern corner along the Arkansas and Oklahoma borders, sits inside one of the more concentrated broiler-chicken production regions in the country. Simmons Foods operates a major processing plant along with hatcheries and feed mills at South West City, supplying a network described by the company as nearly 300 independent poultry growers and more than 20 company-managed farms. That infrastructure is the reason confined poultry production in the broader Elk River basin -- which runs through McDonald County -- has grown substantially since the 1980s, and it is also the reason land near existing grower operations tends to see continued interest from companies looking to expand or replace older barns.

That scale has brought sustained water-quality attention to the watershed: state and academic assessments of the Elk River basin have documented elevated nitrate levels in local springs and streams, tied in part to land application of poultry litter as fertilizer on pasture and hayfields. If you are evaluating a parcel near an active poultry operation, ask about the operation's litter/nutrient management plan (required under its state permit) in addition to checking its physical distance from your building site.

The 2023-2026 permit surge, and why there is no local zoning check on it

Reporting from the Cassville Democrat documents a sharp increase in new CAFO permit applications across four adjoining southwest Missouri counties -- McDonald, Barry, Newton, and Lawrence -- totaling roughly two dozen applications filed with Missouri DNR since January 2023, the large majority for brand-new poultry operations rather than modifications to existing ones. The most widely covered flashpoint from that surge -- a cluster of Class 1C broiler permits adding up to 28 barns and about 1.3 million birds within a single square mile -- sits in Newton County, on the Sarcoxie Prairie northwest of Pierce City, not in McDonald County itself. It's used here only as an example of the kind of density dispute this regional permit wave has produced, not as a McDonald County project.

The regulatory mechanics matter for a McDonald County land buyer regardless of exactly where a given proposal sits: Missouri's state permit program does not set a minimum separation distance or a cap on the number of poultry barns that can be built within a given area, and McDonald County has no zoning ordinance that could impose local setbacks or a conditional-use review either. The one structured opportunity a nearby landowner gets is built into the state permit process itself -- before submitting an operating-permit application, an operator must send neighbor-notice letters to landowners within a set buffer distance (roughly 9,000 feet for the largest Class 1A operations, scaling down to about 3,000 feet for smaller Class 1C operations), and DNR then accepts public comments for 30 days from the date the application is received. If you're evaluating a parcel and want to know whether a notice has already gone out nearby, ask the County Commission and check Missouri DNR's current pending CAFO facility applications list directly, since neither the county recorder nor the assessor's office tracks that separately.

For a landowner on the other side of this -- someone considering putting up poultry barns as a contract grower -- the flip side of no zoning is that there is no county-level rezoning fight or conditional-use hearing to navigate either; the state CAFO permit process (including its own neighbor-notice and comment requirements) is essentially the entire regulatory path. MU Extension in McDonald County and the DNR Water Protection Program are the two starting points for understanding what a specific class of operation requires before committing to a site.
