Costco highlights employee concerns over shopper behavior and lists major manufacturers behind Kirkland products

Costco workers say shoppers often create extra work by leaving trash in carts and around the store and by allowing children to roam unsupervised near toys and seasonal displays, adding cleanup tasks for staff.

The retailer also disclosed that its private‑label Kirkland Signature line is produced by well‑known food manufacturers. Examples include Reynolds Foodservice foil, which bears the Reynolds logo, and Humboldt Creamery, which supplies the Super Premium Vanilla Ice Cream, among other products sourced from large national and international brands.
