President Trump's August 21, 2026 announcement — 300,000 tonnes of imported ground beef, tariff-free, at “25 percent below current market prices” — did not come out of nowhere. It is the latest turn in a story that began with the smallest U.S. cattle herd since 1951 and ran through record retail prices, a flesh-eating parasite that closed the Mexican border for twenty months, on-again-off-again tariffs on the two biggest South American suppliers, the first permanent Big Four plant closure in decades, and a criminal antitrust probe of the packers. This companion timeline to America's Beef with Trump lays out that history, from January 1, 2024 to the present, with every entry sourced. For the price and production numbers behind these entries — retail ground beef, wholesale boxed beef, cash cattle, and monthly beef production — see the companion data page: Beef Prices & Supply, January 2024 – Present.

The Story in Five Numbers

  • 87.2M → 86.2M head: the U.S. cattle herd on January 1 of 2024 vs. 2026 — the 2026 count is a 75-year low, with beef cows (27.6M) the fewest since 1961.
  • $5.67 → $6.69 → record territory: BLS average ground-beef price records — $5.67/lb (Sep 2024), $6.69/lb (Dec 2025), and new records again in mid-2026 (lean/extra-lean series hit $8.65/lb in June 2026). The all-fresh retail beef average hit a record $9.64/lb in April 2026.
  • 20 months: how long the Mexican border was fully or mostly closed to live cattle over New World screwworm, from November 2024 to the August 24, 2026 Douglas, AZ reopening.
  • ~5% of U.S. slaughter capacity: removed when Tyson closed its Lexington, NE plant on January 20, 2026 — part of a record ~$1.1B beef-segment loss.
  • 180,000 tonnes: the duty-free import access added for Argentina alone since October 2025 (20,000t → 100,000t, then +80,000t more in February 2026) — before the new 300,000-tonne plan.

2024: The Herd Bottoms Out, Prices Take Off

  • Jan 31, 2024 — USDA's annual Cattle Inventory report puts the Jan 1 herd at 87.2 million head, down 2% — the smallest since 1951. Beef cows: 28.2 million.

  • Spring 2024 — Drought eases, but ranchers keep liquidating: high interest rates and costs trump better grass. First-half beef cow slaughter runs 15% below 2023 — liquidation slowing, not reversing.
  • Jun 28, 2024 — USDA proposes a Packers & Stockyards Act “unfair practices” rule for livestock markets (later withdrawn in January 2025).
  • Jul 2024 — Fed cattle set a record weekly average of $197.09/cwt; the full-year 2024 fed average ($186.66) finishes 21% above the prior record year.

  • Oct 4, 2024 — McDonald's sues the Big Four packers (Tyson, JBS, Cargill, National Beef), alleging a decade-long conspiracy to restrict supply and inflate prices.
  • Nov 12, 2024 — Tyson reports a $291M FY2024 beef-segment operating loss as record cattle costs crush packer margins.
  • Nov 22, 2024 — Mexico confirms New World screwworm in Chiapas; USDA immediately suspends live-cattle imports from Mexico — the start of a 20-month border saga.
  • Dec 2024 — Calf prices close the year at records (500-lb Oklahoma steers averaged $320.14/cwt for 2024, up 18.6%). Per-capita beef consumption is the highest since 2009 — demand refuses to break.

2025: Tariff Whiplash and a War on Beef Prices

  • Jan 17, 2025 — Brazil fills the entire 2025 “Other Countries” quota (~65,000t) in 17 days — a sign of how hungry the U.S. market is for imported lean beef.

  • Nov 21, 2025 — Tyson announces it will permanently close its Lexington, NE beef plant (~5,000 head/day, ~3,200 jobs) after a record ~$1.135B beef-segment loss — the first permanent major-plant closure by a Big Four packer.

Where It Stands

Two and a half years in, the forces are pulling in opposite directions. Supply: the herd may finally be turning — July's mid-year count ticked up for the first time this cycle — but biology means any rebuild takes years, and packing capacity is now shrinking faster than the herd. Demand: Americans keep buying beef at record prices. Policy: an administration simultaneously investigating packers for high prices, exempting foreign beef from its own tariffs, quadrupling Argentina's quota, and proposing the largest single import action in decades — while ranchers who form a core constituency watch calf prices swing on every announcement. The next entries in this timeline will be written by the implementing executive order (expected by early September), the DOJ packer probe, and the screwworm line in South Texas.

A note on sourcing: entries cite USDA/NASS reports, presidential documents, BLS price series, and trade-press reporting. Two price figures rest on single or secondary sources and are flagged here: the June 2025 ~$6.12/lb ground-beef record (trade press citing BLS) and the April 2026 $250/cwt cash-cattle record (specialized trade press). Price series differ (100% ground beef vs. all uncooked ground beef vs. lean/extra-lean); figures are labeled by series where the sources allow.
