United States v. Archer Daniels Midland (Lysine Cartel)

Lysine is an amino acid mixed into animal feed so chickens and pigs gain weight efficiently. When a few global producers control supply, farmers and meat processors depend on honest competition to keep feed costs down.

In the early 1990s, Archer Daniels Midland dominated US production while Ajinomoto and Kyowa Hakko led in Japan. Instead of competing, executives allegedly held regular meetings—sometimes literally whispering about competitors while the FBI listened from the next table.

The cartel set target prices by region, allocated sales volumes, and monitored whether each company 'cheated' on the deal. Emails and travel schedules later showed how ordinary business trips masked criminal coordination.

Mark Whitacre, an ADM executive, became an FBI informant and wore a wire. His tapes captured phrases that antitrust students still quote—moments where executives joked that competing was the 'enemy' while dividing markets.

The investigation expanded internationally. US prosecutors charged both corporations and individuals, reflecting a policy that prison time deters cartels better than fines alone.

ADM pleaded guilty and paid a $100 million criminal fine— enormous for the 1990s. Several executives received federal prison sentences, a rarity in white-collar enforcement even today.

The lysine case remains the pop-culture face of cartel crime: it showed collusion is not abstract economics but people choosing to break the law in plain language on tape.

Criminal antitrust targets individuals—not just corporate checkbooks.

Agricultural input cartels raise food prices upstream of the grocery aisle.

Whistleblowers and wiretaps can destroy long-hidden conspiracies.

Price fixing and volume allocation in lysine worldwide.

Meetings among ADM and Japanese rivals to enforce targets.

Harm to feed buyers and ultimately meat producers.

Some defendants argued entrapment or disputed meeting characterizations.

ADM later portrayed itself as reformed with stronger compliance.

Civil plaintiffs pursued follow-on damages separately.

If you buy commodities from a tight oligopoly, sudden parallel price moves may warrant scrutiny.

Employees asked to join 'industry coordination' meetings should escalate to counsel.

The case is still used to train executives on antitrust criminal exposure.
