Who makes Kirkland Signature Sliced Bacon (Regular & Thick-Cut, Hickory Smoked)?

No FSIS recall or public-health alert on file names Kirkland Signature bacon or any bacon co-packer for Costco. The Kirkland-brand FSIS actions on record cover other products (a ready-to-eat ham listeria alert and a chicken tortilla soup misbranding alert), so the recall route — usually the fastest way a private-label meat co-packer gets named — surfaces no maker for the sliced bacon.

No establishment lists a Kirkland- or Costco-bacon DBA. Costco runs its own USDA-inspected meat plants (the Costco Wholesale Meat Plant in Tracy, CA, EST. M18532, plus a reported second plant in Morris, IL) and reporting ties Kirkland hot dogs to them, but no public source connects the refrigerated sliced bacon to those plants or to any establishment number. The USDA EST. number printed on a current bacon package would resolve the co-packer deterministically; it has not been read from a retail pack for this check.

The Costco Business Delivery listings for the sliced bacon (items 10181821 and 2001134165, 'Kirkland Signature Bacon, Hickory Smoked, Sliced, 1 lb, 4 ct') have no Wayback snapshots, so the manufacturer/mfName field could not be retrieved for the sliced product. The only Costco/Hormel bacon page available is the separate Kirkland Signature fully-cooked (precooked) bacon, which carries a Hormel co-brand on the label — a different product from the refrigerated sliced staple.

Structurally uninformative here: refrigerated sliced bacon sold in US warehouses is cured and packed domestically, so an absence of import records proves nothing about the co-packer (tier 5 caveat). No route to a maker via customs data.

No Costco or supplier statement names the maker of the sliced Kirkland bacon. Smithfield is the name most often floated — Allrecipes and several food-media pieces cite an estimate that Smithfield accounts for roughly 75-80% of Costco's bacon — but neither Costco nor Smithfield has confirmed a bacon partnership, and the figure is an unsourced estimate. Hormel, the older assumption, was corrected: a Hormel brand representative stated Hormel does not make the sliced Kirkland bacon; the Hormel connection traces only to a discontinued co-branded precooked line.

No litigation naming a Kirkland Signature bacon supplier found.

The recurring theory is that Costco uses several regional pork suppliers for its bacon rather than a single co-packer, with Smithfield as the largest. No verified single maker circulates for the sliced product; the Smithfield attribution remains speculation across every source checked.
