Costco recalls, and other food stores-related recalls, have become an unfortunate but expected part of food safety in America, and this week, the retail giant is in the spotlight again. Recently, Western United Fish Company (dba Annasea Foods Group) announced a recall of the Kirkland Signature Ahi Tuna Wasabi Poke after testing revealed that the product’s green onions were contaminated with Listeria monocytogenes.

The recalled item, packaged on September 18 with a sell-by date of September 22, 2025, was distributed to Costco stores across more than 30 states. While no illnesses have been reported, officials are urging consumers to stop eating the product immediately and either return it for a full refund or discard it safely. This recall not only raises urgent health concerns but also emphasizes how even one compromised ingredient can put thousands at risk.

What Exactly Was Recalled

The Costco Recalls notice applies specifically to Kirkland Signature Ahi Tuna Wasabi Poke sold in clear clamshell containers under item number 17193. Each pack was labeled with the sell-by date of September 22, 2025. The issue wasn’t the tuna itself, but rather the green onions used in the dish. When a supplier batch tested positive for Listeria, it triggered an immediate investigation that led to the voluntary recall.

Distribution of this poke was wide-reaching, hitting stores across at least 32 states and possibly more. Locations in California, Florida, New York, Texas, Washington, and several others were confirmed. That means thousands of households may currently have the product in their refrigerators, which makes timely awareness vital.

For Costco, which built its reputation on quality and consumer trust, recalls like this are serious. Yet, the brand’s swift move to pull the product from shelves shows how important quick response is in food safety.

Why the Risks Are Serious

While some may shrug at a recall when no illnesses are reported, experts stress that Listeria monocytogenes is no small matter. This bacterium can cause listeriosis, a foodborne illness that often begins with flu-like symptoms: fever, nausea, and muscle aches. But in severe cases, especially among pregnant people, older people, infants, and immunocompromised individuals, it can lead to dangerous complications, including miscarriage, bloodstream infections, and even death.

Unlike many other bacteria, Listeria thrives in cold environments. That means refrigerated foods like poke are particularly vulnerable. Ready-to-eat dishes, which skip cooking steps that might kill bacteria, carry added risk when a single ingredient—like those green onions—slips through quality checks. Costco Recalls like this highlight how fragile the system can be, even with strict supply chain oversight.

What Customers Should Do

If you bought the Kirkland Ahi Tuna Wasabi Poke, here’s the bottom line: do not eat it. Check your packaging for item #17193 and the September 22, 2025 sell-by date. If it matches, you have two choices—return it to Costco for a full refund or throw it out immediately. The company has confirmed that customers will be compensated, no questions asked.

If you’ve already eaten the product and feel fine, there’s no need to panic. But if you fall into a vulnerable health category or if you start experiencing symptoms like fever, chills, or stomach distress, contact your healthcare provider quickly. Listeriosis can develop slowly, sometimes taking weeks to show signs.

This advice isn’t just for the consumers who bought the poke. It’s also a lesson in vigilance. Many people assume recalls only matter when an outbreak happens. In truth, recalls are preventative steps to stop outbreaks before they start. Costco Recalls, in this sense, are designed to protect, not just to alarm.

What This Recall Says About Food Safety

The Kirkland Ahi Tuna Wasabi Poke recall fits into a larger trend of recurring food safety alerts across Costco. Earlier this year, other Costco Recalls involved seafood and frozen treats, while competitors like Trader Joe’s and Walmart have also had to pull products. The globalized nature of food supply chains makes absolute control nearly impossible. A single contaminated batch of green onions grown, processed, or shipped abroad can ripple across thousands of miles and into millions of kitchens.

For Costco, transparency and quick action matter. Their willingness to act immediately, notify federal regulators, and issue clear instructions is part of what keeps consumer trust intact. Still, the recall is a wake-up call about the risks tied to ready-to-eat items. Sushi, poke, and other raw or minimally processed foods remain popular, but they demand the highest safety standards.

This particular recall may blow over without illness reports, but its implications will linger. It’s a reminder that the food industry must constantly evolve testing methods, traceability systems, and supplier standards to keep pace with consumer demand for fresh, convenient, and global foods. While Costco Recalls are inconvenient, they also show a system doing its job.
