Costco sells a lot of beef, but the company does not present it as coming from one single place. Its public statements show a mix of sourcing by item, which is why shoppers may be surprised to learn that the answer depends on the specific package in the case or listing online.
Costco does not offer one simple origin answer
Costco says it is “unable to provide an all-inclusive list of items and their country of origin” on its customer service site. The company adds that if a shopper wants help with a particular item, Costco can research that request. That matters because it means there is no public, one page answer covering every beef product sold by the retailer.
That also helps explain why shoppers can come away with different assumptions. Some customers may expect Costco beef to be entirely American because the chain’s fresh meat departments are strongly associated with USDA graded beef. Older Costco materials describe the meat department as carrying USDA Choice beef, but that language does not mean every beef item across Costco’s business comes from the same source or country.
In practice, Costco’s public facing beef pages show that sourcing can vary widely by product and format. The company’s online beef assortment includes branded suppliers and imported products, which signals that origin is not one size fits all across the category.
Some Costco beef is clearly sourced outside the United States
One current example on Costco’s website is Silver Fern Farms Halal 100% Grass-Fed New Zealand 93% Lean Ground Beef. Another listing is a Silver Fern Farms 100% New Zealand Grass-Fed Steak Box. Those product pages make it plain that at least some beef sold through Costco comes from New Zealand, not the United States.
Costco also sells other beef products online under outside brand names, including steaks and roasts from specialty meat companies. Those listings reinforce the broader point that Costco’s beef case is a mix of suppliers rather than a single vertically uniform program. A shopper buying frozen patties, fresh steaks, or online delivery items may be buying from very different supply chains.
Costco’s sustainability materials make the same point in broader terms. The company says it sources products from suppliers around the globe, and its responsible sourcing pages say Costco sources beef from countries with lower deforestation risk. That is not a country by country shopping guide, but it does confirm that the company’s beef sourcing framework is international in scope.
What Costco does say publicly about its beef standards
Costco’s 2025 Sustainability Report gives one of the clearest public clues about its Kirkland Signature beef sourcing. In a biodiversity metric, the company reported that the percentage of Kirkland Signature beef not sourced from Argentina, Brazil, Colombia or Paraguay was 100% for FY25. That does not identify every country Costco does use, but it does show the company is tracking sourcing against specific higher risk regions.
The retailer also says it is an active member of the U.S. Roundtable for Sustainable Beef and that it follows recognized animal welfare audit standards and programs for animal products sold at Costco, including beef. For shoppers, that means the company talks more publicly about sourcing standards and risk controls than about a full itemized origin map.
So where does Costco’s beef actually come from. Based on Costco’s own materials, the most accurate answer is that it depends on the product. Some beef sold by Costco is clearly imported, including from New Zealand, while Costco’s public policies show a broader sourcing strategy shaped by product specific origin and responsible sourcing standards, not a single unexpected secret source.
