The Hidden Cost of “Perfect” Fries: What Really Goes Into McDonald’s Potatoes

McDonald's French fries are one of the most recognizable foods in the world—long, golden, crisp, and almost identical no matter which restaurant you visit.

 But behind that consistency lies a process most customers never hear about, and it raises questions about what it takes to produce such flawless results on such a massive scale.

To achieve the signature shape and color of McDonald’s fries, the company relies heavily on a single type of potato: the Russet Burbank. This potato is long and uniform, ideal for creating fries that fit the brand’s standard image. But it is also notoriously difficult to grow. The Russet Burbank is highly vulnerable to blemishes, discoloration, and a condition called net necrosis, which causes dark lines to form inside the potato. These imperfections make the potato unusable for McDonald’s strict visual standards, placing enormous pressure on farmers to deliver spotless crops.

To prevent net necrosis, farmers use a pesticide known as Monitor. The chemical is powerful enough that, once applied, farmers are required to stay out of their own fields for several days due to its toxicity. This practice highlights the intensity of the production system: protecting the uniform appearance of a french fry takes precedence over traditional farming rhythms. The use of chemicals this strong underscores how tightly managed the process must be to meet corporate expectations.

The story doesn’t end at harvest. Even after the potatoes are pulled from the ground, they are not immediately ready for consumption. Because the chemical treatments leave residues within the potatoes, they must be stored for nearly two months in enormous, climate-controlled sheds. These storage facilities are engineered to gradually remove the remaining chemicals, allowing the potatoes to reach levels considered safe for processing. These sheds can be the size of sports arenas, designed specifically to hold millions of pounds of potatoes awaiting their release into the supply chain.

Once the potatoes have aged and the chemical levels decline, they are processed, cut, partially fried, frozen, and shipped worldwide. By the time they reach a customer’s tray, they look simple and familiar—yet the journey behind them is anything but. So much of the system is built on achieving a flawless visual ideal that the natural variability of farming has been almost completely engineered out of the picture.

What many people don’t realize is that the iconic McDonald's fry is less a product of simple ingredients and more the result of a heavily controlled industrial process. The demand for perfection—every fry the same shape, color, and texture—drives farming practices, chemical use, and storage systems that go far beyond traditional agriculture. Understanding this process adds a layer of complexity to something most of us eat without a second thought, revealing how much effort goes into making a product appear effortless.
