Idaho potato companies have been mashing consumers with price collusion, anti-trust suit alleges

Nov. 23—The four largest producers of frozen potatoes and french fries, including two companies based near Boise, have supersized their profits over the last few years by gouging American consumers through higher prices that they improperly set by agreement, according to a federal anti-trust lawsuit filed this week.

The suit, filed in Illinois by California-resident Karen Pollack, claims that J.R. Simplot Company and Lamb Weston, both based in Idaho, conspired with competitors McCain Foods and Cavendish Farms, both based in Canada, to collude instead of competing for larger shares of the market.

Combined, those four companies control about 95% of the frozen potato market.

According to the suit, rather than compete on the open market for a higher percentage of customers, the companies agreed to similar price increases to raise the price of frozen potato products by 47% from 2022 to 2024.

While sales have remained relatively flat, Lamb Weston earlier this year reported profits 111% higher than 2023 for the first quarter of this year.

"Defendants' wrongful and anticompetitive actions had the intended purpose and effect of artificially fixing, raising, maintaining, and stabilizing the price of Frozen Potatoes," the suit states. "On behalf of a proposed class of tens of millions of consumers nationwide" the suit seeks to end the "illegal scheme, to recover damages, and to restore competition in the Frozen Potato marketplace."

In 2023, Idaho led the nation in potato production and Washington was second. Combined, the Gem and Evergreen states produced about 56% of all the 44 billion pounds of potatoes grown in the United States, according to the U.S. Department of Agriculture.

Of those potatoes grown, about 70% go to companies like Simplot, which use specialized machines and processes to convert the raw potatoes into french fries, tater tots and potato chips. They are sold in frozen bags of potatoes at grocery stores and at fast food restaurants.

As the finished potato prices have soared the last two years, potato farmers in the Columbia River valley have not received the same windfall.

In 2023, the average price for 100 pounds of potatoes in Washington was $11.20, which was up 23% from 2022. In Idaho, farmers fared worse, selling their potatoes for an average of $9.63 for 100 pounds, which was down 11% from 2022.

But those numbers don't track with the price hikes shown by the four major producers, the suit alleges. According to Federal Reserve Economic Data, the producer price index of frozen potatoes had remained near constant but climbed slightly from 2006 to 2020, but it then rose sharply in 2021.
