Check your freezer. Seriously. If you’re a regular at the Costco warehouse, you probably have a vacuum-sealed pack of smoked salmon tucked away for a quick brunch or a bagel spread. But lately, the Costco salmon recall has turned those easy Sunday mornings into a bit of a headache. This isn't just another corporate "oops" moment; it's a specific safety concern involving Listeria monocytogenes, and if you've got the wrong batch, it's not something you want to mess around with.
Food recalls happen all the time. Usually, it's a labeling error or some undeclared allergen like peanuts. This is different.
The situation primarily involves Acme Smoked Fish Corp., a massive supplier that stocks the shelves of major retailers, including our favorite bulk-buy giant. They flagged certain packages of Kirkland Signature Smoked Salmon after routine testing caught a potential problem. It’s scary because Listeria isn't like a standard stomach bug. It’s a hardy little bacterium that can survive—and even thrive—in the cold, damp environments of food processing plants.
Why the Costco Salmon Recall is Different This Time
Most people think a recall means every piece of fish in the store is tainted. That’s not how this works. The Costco salmon recall specifically targeted Kirkland Signature Smoked Salmon purchased between October 9 and October 13, 2024. If you bought your lox in July, you’re almost certainly fine. If you bought it yesterday, you're likely fine too, because the inventory has been purged.
The issue is that "in-between" window.
Acme Smoked Fish Corp. issued the voluntary recall because a single lot—Lot Number 8512801270—showed up positive for Listeria during a quality check. Honestly, it’s a bit of a needle in a haystack situation. But when it comes to pathogens that can cause meningitis or pregnancy complications, "good enough" isn't an option.

What is Listeria anyway?
It’s a germ. Specifically, Listeria monocytogenes. Unlike Salmonella, which usually makes you feel like you're dying for 48 hours and then lets you go, Listeria is patient. It can stay in your system for up to 70 days before you show a single symptom.
For a healthy adult? You might just get a fever, a stiff neck, or a nasty headache. Maybe some diarrhea. But for "vulnerable" populations—the elderly, those with weakened immune systems, and especially pregnant women—it’s a nightmare. In pregnant individuals, it can lead to miscarriages or stillbirths, even if the mother barely feels sick. That’s why the FDA and CDC get so aggressive about these things.
The Specifics: Was Your Fish Affected?
You need to look at the blue plastic film on the package. Costco is pretty great about tracking who buys what through their membership system. If you were in the "danger zone," you probably already got a robocall or an email. But don't rely solely on that. Tech glitches happen.
The recalled product is the Kirkland Signature Smoked Salmon twin pack (two 12-oz packages sold together).
- Lot Number: 8512801270
- UPC Code: 0 96619 25150 2
- Best By Date: November 13, 2024 (though by now, that date has passed, many people keep these in the freezer).
If your package doesn't match that exact lot number, you can breathe a sigh of relief. Acme Smoked Fish confirmed that no other lots were impacted. They caught it early, which is exactly how the system is supposed to work, even if it feels chaotic to the consumer.

The Supply Chain Problem: Why Smoked Fish?
Smoked salmon is a "ready-to-eat" (RTE) food. This is a technical term that basically means you don't cook it before you eat it. Because there’s no "kill step"—like frying a burger to 160 degrees—any bacteria present at the packaging stage goes straight into your mouth.
Cold-smoking is particularly tricky. The fish is treated with smoke at temperatures that don't actually cook the flesh. It keeps that buttery, raw texture we love, but it doesn't kill pathogens. The safety of the product relies entirely on the cleanliness of the facility and the brine used during processing.
Lessons from the Acme Smoked Fish Incident
Acme is a legend in the seafood world. They’ve been around since the early 1900s and are widely considered to have some of the best safety protocols in the industry. The fact that a Costco salmon recall happened with a top-tier supplier shows just how persistent Listeria is.
The bacteria can hide in floor drains, on the wheels of forklifts, or in the microscopic cracks of stainless steel tables. Once it establishes a "biofilm," it's incredibly hard to scrub away.
What You Should Do Right Now
Stop eating the fish. Don't even give a "test nibble" to the dog.

- Verify the Lot: Check that number on the back. 8512801270.
- Do Not Trash It Yet: If you want your money back, take it to the Costco returns counter. They are famous for their "no questions asked" return policy. Even if the package is open, or even if you've eaten half of it, they will give you a full refund.
- Sanitize Your Fridge: This is the part people skip. If the package was leaking or if you handled the fish and then touched the fridge handle, you could have cross-contaminated your kitchen. Wipe down your shelves with a mild bleach solution (one tablespoon of unscented bleach to one gallon of water).
- Monitor Your Health: If you already ate the fish, don't panic. The vast majority of people who consume contaminated food do not get seriously ill. However, if you develop a high fever, severe headache, or neck stiffness in the next few weeks, tell your doctor specifically that you may have been exposed to Listeria.
The Myth of "Organic" or "Premium" Safety
There's a common misconception that buying "premium" or Kirkland Signature (which is often rebranded high-end product) protects you from recalls. It doesn't. In fact, large-scale distribution chains are sometimes more susceptible to widespread recalls because one small error in a massive factory affects thousands of units across multiple states.
The Costco salmon recall didn't happen because the fish was "cheap." It happened because of a microscopic lapse in a very complex cold-chain environment.
The Broader Context of Food Safety in 2026
We're seeing more recalls lately, but that's actually a weirdly good sign. It means testing technology is getting better. We can now detect parts per billion of a pathogen that would have gone unnoticed ten years ago. Whole Genome Sequencing (WGS) allows investigators to link a specific strain of Listeria in a patient to a specific factory in a matter of days.
Costco takes these hits to their reputation because the alternative—letting people get sick—is much worse for the bottom line.
Practical Steps Moving Forward
If you're worried about future seafood safety, you don't have to quit salmon. Just be a smarter shopper.
- Rotate Your Stock: Use a "first in, first out" method in your freezer so you aren't sitting on old, potentially recalled batches.
- Stay Subscribed: Don't opt-out of those annoying Costco membership emails. They use that data for precisely this reason.
- Heat it Up: If you are in a high-risk group (pregnant or immunocompromised), consider cooking your smoked salmon. Tossing it into a hot pasta dish or a frittata kills Listeria instantly.
The Costco salmon recall is a reminder that our food system is fragile but transparent. You’ve got the lot numbers, you’ve got the refund path, and now you’ve got the facts. Check your fridge, get your money back, and maybe stick to the rotisserie chicken for a few days while the dust settles.
