Common questions about Kirkland Signature
Who makes Kirkland Signature pet food?
Diamond Pet Foods, under contract with Costco. Kirkland Signature is Costco's private-label; Diamond manufactures it at their facilities alongside Taste of the Wild and other Diamond-made brands. Price-per-pound value is among the strongest in US retail because of Costco's supply-chain leverage. Nature's Domain is the grain-free sub-line.
Has Kirkland Signature been recalled?
Yes, May 2012 — Kirkland Signature dog foods were part of the industry-wide Diamond Pet Foods Gaston, SC plant salmonella recall. That plant-wide event affected multiple Diamond-manufactured brands simultaneously. Kirkland has had no other significant US enforcement-action recalls since. Shared-manufacturer context is the main recall consideration.
