Who makes Kirkland Signature Trail Mix, 4 lbs?
No reliable public evidence identifies the manufacturer of Kirkland Signature Trail Mix, 4 lbs as of October 12, 2026.
The common claim
What’s commonly claimed, and what the evidence supports
There is no widely repeated answer for who makes Kirkland Signature Trail Mix. Unlike some Kirkland items, no co-brand, Costco catalog listing, or recall notice names its maker. John B. Sanfilippo & Son, a large private-label nut and trail-mix processor, lists Costco among its accounts and is a plausible candidate, but no tier 1-5 source connects it to the Kirkland trail mix, so the maker is not publicly documented.
Evidence & sources
Costco does not disclose its suppliers, and no tier 1–5 source names the maker of this product. Below are the databases and records we checked, and what each one returned.
Recall sweep (FDA openFDA food-enforcement API; CPSC SaferProducts; FSIS) July 5, 2026
openFDA food-enforcement search for 'trail mix' + 'kirkland' returned 0 matches; CPSC does not cover packaged food and returned nothing relevant. The 2016 SunOpta sunflower-kernel Listeria contamination triggered a large cascade of downstream trail-mix and snack recalls (including Brown & Haley's Mountain Thins Trail Mix, Kroger Cranberry Delight Trail Mix, and Kashi Trail Mix bars), but no public recall notice named Kirkland Signature Trail Mix, and none identified a Kirkland co-packer. No recall route surfaced a maker.
Costco's manufacturer field on Costco.com product pages (costco.com blocks bots, Wayback only) July 5, 2026
The current Kirkland Signature Trail Mix listings (item #100752766, 4 lb; item #100770569, snack packs) have no Wayback snapshot, and the only archived Costco page (the older .product.100752766.html template, snapshot 2025-03-17) predates Costco's manufacturer field that resolved the Kirkland popcorn and granola-bar listings. The manufacturer-field route is unavailable for this item; capturing the live product page's manufacturer field still needs a manual browser check.
CourtListener / RECAP federal court records (v4 search API) July 5, 2026
Search for "Kirkland Signature" + "trail mix" returned 0 opinions. No litigation names a supplier of Kirkland Signature Trail Mix.
News / trade-press / executive-statement sweep (Google/Bing news, food trade press) July 5, 2026
No article or executive statement names the maker of Kirkland Signature Trail Mix. John B. Sanfilippo & Son (Fisher, Orchard Valley Harvest, Squirrel Brand) is a major private-label nut and trail-mix processor that lists Costco among its key accounts and is a plausible candidate, but no source ties JBSS to the Kirkland trail mix specifically.
On-package / co-brand / origin check (Costco listing, Amazon and reseller product copy) July 5, 2026
The mix's M&M's candies are a Mars product used as an inclusion, not the maker; the pack states it is processed and packed in the USA and 'Distributed by Costco Wholesale', with no co-packer or 'made by' entity named on the label.
ImportYeti / customs bills of lading and community roundup-article scan July 5, 2026
Import route structurally weak here (US-market trail mix is packed domestically and Costco masks many shipments via freight forwarders, so absence proves nothing). A 'Snackathon Foods' Kirkland trail-mix page is a third-party reseller listing (now returning HTTP 404), not a manufacturer. No roundup article or community thread converges on an evidenced maker.
