Single Source vs. Co-Mingled Ground Beef: What's Actually in Your Package

Pick up a package of ground beef at any major grocery store. Turn it over. The label will tell you the fat percentage, the weight, the price per pound. What it almost certainly won't tell you is how many animals are in that package.

The answer, for most commercially produced ground beef, is somewhere between dozens and hundreds.

This is co-mingling — the standard industry practice of combining trim and lower-grade cuts from many different animals, often from many different facilities and countries, into a single ground product. It's legal, it's common, and most consumers have no idea it's happening.

How Commercial Ground Beef Is Made

When a beef processing plant breaks down a carcass, the premium cuts — ribeyes, sirloins, tenderloins — go one direction. The trim, the scraps, the lower-value pieces go into a separate stream that becomes ground beef.

At large-scale facilities, that trim from hundreds or thousands of animals gets combined in industrial grinders. The resulting ground beef is then tested, packaged, and shipped. Your one-pound package represents a tiny slice of a very large, very mixed batch.

The USDA requires ground beef to be labeled with its country of origin — but that label can read "Product of USA, Canada, Mexico" all at once. The beef in your package may have come from animals raised in multiple countries, processed in multiple facilities, shipped and recombined.

What a Recall Actually Looks Like

The practical consequence of co-mingling becomes clearest during a recall.

When a contamination issue is detected in co-mingled ground beef, the recall is massive — because tracing the source requires unwinding a supply chain that touched hundreds of animals and multiple facilities. Recalls often involve millions of pounds of product because the batch contaminated a huge production run before anyone identified the problem.

With single-source ground beef, a contamination issue traces back to one animal, one farm, one processing run. The affected quantity is measured in pounds, not tons.

What Single Source Actually Means

Single-source ground beef comes from one animal. Every pound in your package came from the same animal that produced your steaks, your roasts, your short ribs.

This matters for a few reasons:

Flavor consistency. Ground beef from a single animal has a consistent fat distribution, flavor profile, and texture. Co-mingled beef averages across many animals — good ones and mediocre ones alike.

Traceability. If you want to know where your beef came from, single-source makes that possible. Co-mingled beef makes it essentially impossible.

Quality floor. Single-source ground beef is only as good as the animal it came from. For a locker sourcing from quality family farms, that floor is meaningfully higher than what goes into commercial ground beef trim.

What This Looks Like at Milo Locker

Every bundle we ship contains ground beef from the same Angus-cross animal that produced the steaks and roasts in that box. Our 85/15 ground beef is not trimmed from dozens of animals and recombined. It comes from one farm, one animal, processed at our locker in Milo, Iowa.

We don't co-mingle. Not because it's complicated to say, but because it changes what ends up in your freezer.

The Farmstead Ground Beef bundle — 20 pounds of single-source 85/15 — exists specifically for families who go through a lot of ground beef and want the same traceability for their everyday cooking that they'd expect from a premium steak.

The Label Isn't Lying — It's Just Not Telling You Everything

Grocery store ground beef isn't fraudulent. The label accurately describes what's inside. But it doesn't volunteer information about where the beef came from, how many animals contributed to that package, or how the supply chain was structured.

Single-source ground beef requires asking different questions when you buy beef. Once you know the difference, it's hard to go back to not asking.
