As of April 2026, the DOJ is conducting a criminal investigation into the nation’s largest beef processors for potential antitrust violations.

The probe focuses on the "Big Four" meatpackers, who control roughly 85% of the U.S. beef market:

  • Tyson Foods
  • Cargill
  • JBS USA
  • National Beef Packing Co.

Key Allegations

  • Investigators are looking for evidence of criminal anticompetitive conduct, including:
  • Price-Fixing: Artificially inflating the price of beef for consumers.
  • Collusion: Coordinating to lower the prices paid to cattle ranchers.
  • Monopolistic Behavior: Using market dominance to stifle competition.

Current Status

Criminal Probe: While civil investigations have occurred in the past, the current inquiry is criminal, following a formal request for action by the Trump administration in late 2025.

Industry Response: The meatpacking companies deny wrongdoing, attributing high prices to supply chain issues and record-high cattle costs.
