Industrial Farming and Big Food: Where Your Food Really Comes From

This is what industrial farming and big food look like. The photos below are real and credited, taken at oilseed crushing plants, feedlots, egg and pig barns, snack factories and farm fields. Each caption states only what its photo shows. A few places don’t allow cameras, so they’re shown as photorealistic illustrations marked AI-generated. Where a claim needs evidence, we link the guide that has it.

The photo above is an aerial view of cattle on a feedlot, taken for the EPA’s Documerica project in 1972. The EPA calls this kind of place an animal feeding operation: animals are confined and fed for 45 days or more a year, on ground where no crops or forage grow. The industry has grown since then.

How canola and seed oil is made

Canola oil and soybean oil are made in plants like these. The seeds are crushed, a solvent pulls out the rest of the oil, and the oil is then refined, bleached and deodorized into the clear oil on the shelf. Our seed oils guide walks through each step and what the research says.

Palm oil isn’t a seed oil, but it’s the fat in a long list of packaged foods. In Malaysian Borneo, rainforest has been cleared for oil palm plantations, and mills process the fruit on site.

How french fries and chicken nuggets are made

Frozen fries and chicken pieces are made in factories, shipped frozen and finished in a fryer. Most of these plants don’t allow cameras, so the freely licensed photos mostly show the outside, or the steel.

To show what happens inside, here are labelled AI illustrations of a fry line, a nugget line, a deboning line and a fast-food fryer bank.

Cattle feedlots and meat packing plants

Here is where the meat in the meat case comes from. Concentration is the part you can’t see in a photo. According to USDA’s Economic Research Service, in 2019 the four largest meatpackers handled 85% of steer and heifer slaughter and 67% of hog slaughter. Our food systems guide explains why that matters for prices and for resilience.

Factory farming: caged chickens, gestation crates and pig farms

Battery cages for laying hens and gestation crates for sows are the images most people picture when they hear “factory farm”. Two of these photos come from animal-welfare investigations. They show conditions at those farms on those dates, not every farm. Our egg label guide explains what “cage-free”, “free-range” and “pasture-raised” legally mean.

How chips, Doritos and corn syrup are made

Ultra-processed food is made on lines like these: corn becomes dough, then chips, then a bag. Corn wet mills turn corn into starch and syrups, and sugar refineries supply the rest of the sweet. Our ultra-processed foods list shows how to spot these ingredients on a label.

Crop dusting, irrigation and algae blooms

Industrial agriculture covers a lot of ground. Planes spray fertilizer and pesticides, and irrigation pivots water huge single-crop circles. The EPA says nitrogen and phosphorus from fertilizer and manure can wash off fields when it rains. That runoff feeds algal blooms and dead zones, like the green water in Lake Erie below.

What you can do with this

The point isn’t despair. It’s knowing what you’re buying. Every step away from this system counts, whether that’s buying a share of beef from a farm, choosing eggs by what the label actually means, rendering your own tallow or baking your own bread. You don’t have to do all of it to make a difference. Pick one.
