FAT RESEARCH SERIES — PORK

FAT Research Series — Economic Concentration

Why packer concentration, contract production, and vertical coordination must be analyzed together—and why those structures also matter for label transparency.

Executive Summary

The U.S. pork industry is highly concentrated in processing and substantially more vertically coordinated than beef. USDA ERS reported in 2024 that the four largest firms handled about 67% of hog purchases, while older and still-cited USDA ERS work on vertical coordination documented the rapid growth of contracts and integrated operations in hog marketing. FAT’s pork supply-chain work shows why that matters for transparency: when ownership, procurement, feeding, and processing are increasingly coordinated, independent price signals and independent information can both weaken.

How Concentration Should Be Analyzed in Pork

Pork cannot be understood through CR4 alone. Pork also requires attention to vertical coordination—especially production contracts, ownership ties, and managed procurement channels. ERS’s work comparing pork and broiler coordination remains foundational because it explains how contracts and integration can solve transaction problems while also concentrating control over output, specifications, and information.

Pork’s Structural Distinctive: Integration

ERS found that about 40% of hog sales to packers were already coordinated by contracts and integrated operations in 1998, up sharply from prior decades. Later USDA work and industry reporting show that the open market continued to thin as large integrated systems expanded. Claire Kelloway’s Food & Power reporting on pork and livestock concentration is especially useful in showing how this appears from outside the academy: concentrated processor ownership, global capital, and contract dependence together shape who bears risk and who controls the terms of trade.

FAT’s pork map adds another layer by connecting slaughter plants, corporate ownership, and CAFO geography. For FAT, the core issue is not only whether concentration raises classic competition concerns, but also whether integrated supply chains reduce the visibility of origin, farm identity, welfare practices, and production distinctions that consumers might reasonably want to know.

Price Discovery and Information Loss

AMS’s baseline study on livestock marketing trends is relevant here as well because it documents how price reporting systems interact with changing transaction forms. Where fewer hogs move in transparent negotiated channels, producers and downstream buyers may rely more heavily on administered, formula, or internal transfer prices. That can reduce the public informational content of the market.

In pork, the same structure can flatten product identity. Where integrators control genetics, feed formulations, veterinary protocols, and processing relationships, labels can present a simplified marketing story while omitting the structure behind the product. FAT therefore treats economic concentration as a disclosure category because concentration affects what categories of truth are feasible, scalable, and commercially convenient to disclose.

Conclusion

Pork concentration is best understood as a combination of packer concentration and vertical coordination. CR4 and HHI remain useful, but they do not by themselves capture the dependence created by contracts and integrated production. FAT’s pork analysis argues that this concentration should be evaluated not only through antitrust screens, but through its effect on transparency, traceability, and the competitive visibility of independent production.

Sources and Methods

FAT uses a mixed-method approach. These papers rely on USDA Economic Research Service and Agricultural Marketing Service publications, DOJ/FTC antitrust guidance, Claire Kelloway’s Food & Power reporting, and FAT’s own supply-chain mapping pages. Concentration is evaluated with four complementary tools: (1) CR4, the share held by the four largest firms; (2) HHI, the standard DOJ/FTC concentration screen; (3) regional concentration, because local procurement and processing options often matter more than national averages; and (4) vertical coordination/integration, including contracts, formula pricing, and integrator control over inputs and processing. FAT treats these metrics as descriptive indicators, not as stand-alone proof of unlawful conduct.
