The government cheese caves in Missouri are converted limestone mines, most famously the Springfield Underground, a 3.2-million-square-foot former quarry in Springfield that has stored both government and private-company cheese since the 1960s. But the federal dairy stockpile was never concentrated there, or in any single cave. At its 1980s peak, government-owned cheese sat in more than 150 warehouses across 35 states, and Missouri’s underground facilities held only a small share of it.
The Springfield Underground and What’s Actually Inside
The Springfield Underground is real, and it did receive government cheese. Photographic evidence from 1982 shows pallets of boxes labeled “USDA Food” and “Pasteurized Process American Cheese” inside the facility. At that same moment, though, the site held less than 100,000 pounds of the federal stockpile — a tiny fraction of the national total.
Most of the cheese aging in Missouri’s limestone has always been private. Kraft Heinz has used the Springfield Underground since the early 1960s. Dairy Farmers of America has kept millions of pounds of dairy ingredients there for roughly three decades. When people hear “cheese caves in Missouri,” they are usually picturing commercial storage and attaching the government label to it.
Kansas City’s SubTropolis, another massive underground complex carved from limestone, spans roughly 10 million leasable square feet and carries USDA and FDA approval for storage. Converted mines in Kansas and Wisconsin have also served as cold-storage hubs. The federal surplus moved through a distributed network of these sites and conventional above-ground refrigerated warehouses, coordinated by the USDA’s Commodity Credit Corporation.1United States Department of Agriculture (USDA).

The 1.4 Billion Pound Myth
A claim circulating online says the government keeps 1.4 billion pounds of cheese in caves beneath Missouri. That figure conflates two different things. About 1.4 billion pounds of natural cheese do sit in American cold storage at any given time, but the overwhelming majority belongs to private dairy companies.2United States Department of Agriculture (USDA).

Even at the height of the surplus, the numbers were nowhere near the viral claim. In January 1982, total U.S. cheese in cold storage reached 717 million pounds. Only about 255 million pounds was government cheese, and the Springfield share of that was negligible.
Why Limestone Caves Work for Cheese
Limestone mines hold a natural advantage for food storage. The rock walls maintain a steady 55 to 60 degrees Fahrenheit year-round without heavy mechanical cooling.3Business Insider.

The thick rock also buffers humidity shifts and surface weather.
The savings are substantial. Refrigerating millions of square feet above ground takes enormous energy. Underground facilities use the geology to do most of the work, with dehumidification handling the rest. The private dairy industry moved into these spaces voluntarily, well before the federal surplus made underground cheese a national talking point.
How the Government Ended Up With So Much Cheese
No one set out to fill caves with cheese. The stockpile was a byproduct of dairy price supports dating to the Agricultural Act of 1949, under which the government bought surplus butter, cheese, and nonfat dry milk whenever market prices fell below a set floor. The point was to guarantee dairy farmers a minimum price for their milk.
By the late 1970s, American dairy farms were producing far more milk than the market could absorb, and the government kept buying. By December 1981, more than 560 million pounds of cheese had piled up in warehouses nationwide. That month, President Reagan authorized the release of 30 million pounds for free distribution to low-income households, the beginning of what most people picture when they hear “government cheese.”4Ronald Reagan Presidential Library.

What the Caves Hold Now
The federal dairy surplus is much smaller now than during the 1980s crisis, and Missouri’s underground facilities serve primarily as private commercial storage. Kraft Heinz still ages cheese in the Springfield Underground. Dairy Farmers of America still keeps millions of pounds of dairy ingredients there. The federal government continues to buy surplus dairy when market conditions call for it, and the CCC still contracts with warehouses around the country, but the image of endless underground corridors packed with government cheese belongs more to the Reagan era than to today.
Total U.S. cheese in cold storage remains above 1.38 billion pounds as of early 2026.2United States Department of Agriculture (USDA).

If dairy prices crash again, the limestone caves that made headlines in the 1980s are still there, still cool, and still ready.
If You Are Looking for the Cheese Itself
If what brought you here is the cheese and not the cave, the surplus reaches people through The Emergency Food Assistance Program, run by the USDA’s Food and Nutrition Service. TEFAP sends American-grown USDA foods to state agencies, which distribute them through local food banks and pantries at no cost to eligible households.5Food and Nutrition Service.

Eligibility is set at the state level within a federal range of 185 to 300 percent of the poverty guidelines, so many households earn well above the floor and still qualify.6Food and Nutrition Service.
