Who makes Kirkland Signature Mild Italian Sausage, 56 oz?
No reliable public evidence identifies the manufacturer of Kirkland Signature Mild Italian Sausage, 56 oz as of July 5, 2026.
The common claim
What most answers say — and what the evidence supports
There is no prevailing claim to debunk — top-ranking results for this product are retail listings and recipe posts, and the who-makes-it listicles skip it entirely. The only specific claim on record is a single barbecue-forum post asserting the sausage came from 'NY Sausage Company', a former Costco vendor — an unverified tier-6 claim with no corroboration. Costco does not disclose the maker, and no tier 1–5 evidence identifies one; the USDA establishment number printed on the package is the deterministic route left unread.
Evidence & sources
Costco does not disclose its suppliers, and no tier 1–5 source names the maker of this product. Below is the documented search — every database and record we checked, and what each one returned.
FSIS recall and public-health-alert records (swept via web search of fsis.usda.gov recall pages; the FSIS recall API and site block automated fetches, HTTP 403) July 5, 2026
No FSIS recall or alert names Kirkland Signature Italian sausage or any sausage co-packer for Costco. Kirkland-brand FSIS actions on file cover other products (ready-to-eat ham listeria alert, chicken tortilla soup misbranding alert); the recall route surfaces no maker.
FSIS Meat, Poultry and Egg Product Inspection Directory (full XLSX parsed from the 2025-08-14 Wayback snapshot, 6,969 establishment rows) July 5, 2026
No establishment lists a Kirkland or Costco Italian-sausage DBA. Costco operates its own USDA-inspected plants — 'Costco Wholesale Meat Plant', Tracy, CA (EST. M18532, meat processing) and press reports describe a second plant in Morris, IL — and reporting documents Kirkland hot dogs coming from them, but no public source ties the fresh Italian sausage SKU to any establishment number. The USDA EST. number printed on the package would resolve this deterministically; it has not been read from a current package as of this check.

ImportYeti (US customs bills of lading) July 5, 2026
Automated access blocked (HTTP 403). Route is structurally weak here regardless: fresh Italian sausage sold in US warehouses is produced domestically, so absence of import records proves nothing (tier 5 caveat).
Costco.com product listings and customer-service pages (via Wayback snapshots; costco.com blocks automated fetch) July 5, 2026
Product pages for the 56 oz and 3.5 lb Mild Italian Sausage carry no manufacturer disclosure, and no Costco FAQ or help page names any Kirkland meat supplier — the pet-food FAQ remains the only Kirkland supplier disclosure found on costco.com.
News and executive-statement sweep (Google/Bing news, trade press) July 5, 2026
No news article or executive statement names the maker of Kirkland Signature Italian sausage. Food-media coverage (The Kitchn's 2024 review and similar) praises the product without naming a producer; unusually, the who-makes-it content mills have not covered this SKU at all.
Community/rumor scan (Reddit r/Costco, The Virtual Weber Bulletin Board, listicles) July 5, 2026
One forum post (The Virtual Weber Bulletin Board) claims the sausage came from 'NY Sausage Company', described as a former Costco vendor whose product Costco moved under the Kirkland label — a single uncorroborated tier-6 claim with no supporting evidence found anywhere else. No other name circulates.
