Evidence summary

What the Costco data means.

Costco has 1 product record in the current NonToxic.com database, spanning 1 category: Household Products. The average score of 5/100 is useful for screening, but shoppers should still inspect product-level records because packaging, processing, test year, and contaminant fields can vary inside the same brand.

The current evidence mix for Costco is 1 high confidence. Source labels represented on this page include samples.tsv (1), and test-year labels include 2024 (1). 1 records still need a more specific source URL and 0 records still need a normalized test year, so these items should drive brand transparency requests before any broad safety claim is made.

For practical review, start with Costco Seasoned Rotisserie Chicken, then use the category page to compare competing products because this brand set does not yet contain a separate stronger-scoring item. Use the linked category page to compare competing brands, packaging formats, source confidence, and newer test years before treating the brand record as complete.

How to use this brand page.

Use this page to decide what to inspect next, not to label every Costco product safe or unsafe. A brand with one listed product has a narrow evidence base, while a brand with many products may mix lower-concern records with elevated or highest-concern records. The most defensible workflow is to open the product page, read the source row, compare the category alternatives, and submit a correction if a newer lab report or packaging disclosure changes the evidence.
