Costco does not source beef from Argentina and publishes transparent tracking of their meat origins for Kirkland beef

Majority view

Evidence indicates Costco has instructed suppliers that Kirkland Signature items containing beef should not be sourced from Argentina, Brazil, Colombia, or Paraguay until comprehensive tracing and monitoring systems are in place, so the claim that Costco does not (currently, as a matter of policy) source beef from Argentina for Kirkland-branded items is supported. At the same time, available information shows Costco uses traceability systems, labeling, and at least pilot blockchain programs in its beef supply chain, but this is not equivalent to fully public, consumer-facing "transparent tracking" of meat origins for all Kirkland beef products; country-of-origin and origin codes are typically on packaging or required by regulation, and Costco’s own customer service states it cannot provide an all‑inclusive list of items and their country of origin. Overall, the first part of the claim (no Argentina sourcing for Kirkland beef) is well supported, while the second part overstates the level and openness of Costco’s tracking and disclosure to consumers.
