Costco has built one of the most successful retail models in the world by doing something most competitors would never consider – offering customers fewer choices.
While a typical supermarket may carry 30,000 to 60,000 products and big-box retailers often stock more than 100,000 items across categories, Costco generally limits its selection to roughly 4,000 stock-keeping units (SKUs) at any given time.
That approach may seem counterintuitive, but it serves a purpose. It allows Costco to focus on products it believes deliver strong value while also giving the company greater oversight of the items it sells.
The strategy has helped Costco earn a reputation for quality. But that doesn’t mean problems never occur.
Even companies with rigorous standards occasionally face recalls, whether due to manufacturing errors, contamination concerns, labeling mistakes, or other issues.
When that happens, Costco typically acts quickly to notify members and remove affected products from stores.
The latest example of this involves a popular lactose-free milk product sold exclusively through Costco.
While the issue does not involve contamination by bacteria or foreign materials, the company is urging customers not to consume certain packages and instead return them for a full refund.
Costco issues recall notice for Lactantia milk
Costco has issued an important recall notice for Lactantia UltraPur 2% 20g Protein & Lactose Free Milk in the 2-liter package size.
According to a notice distributed to members, Lactalis Canada is recalling the product with an expiration date of June 22, 2026, sold under Costco item number 1987085. Costco records indicate that affected customers may have purchased the product at Costco between May and June 2026.

The recall was initiated because the milk was found to contain higher-than-intended levels of vitamins A and D.
Specifically, Lactalis Canada said the product is being recalled due to “observed over-fortification of Vitamin A and D compared to the recommended daily intake limit,” which the company said may represent a food safety risk.
Customers who have the affected milk are being instructed not to consume, serve, sell, distribute, or otherwise use the product. The company advises anyone with concerns or symptoms to contact a physician.
The recall applies only to the specified Lactantia UltraPur 2% milk with the June 22, 2026 expiration date and does not affect other Lactantia UltraPur products.

Costco’s recall response is part of its customer-first approach
One reason Costco maintains such strong customer loyalty is the way it handles recalls and returns.
When a recall affects a product sold through the warehouse chain, Costco frequently uses its membership database to identify potentially affected customers and contact them directly. In this case, the company notified members whose purchase history indicated they may have bought the recalled milk.
Costco is also offering full refunds for the recalled milk. Customers can simply bring the affected product to a Costco warehouse and receive their money back.
That policy reflects Costco’s broader philosophy on returns.
Costco is famous for its risk-free satisfaction guarantee, which allows members to return most merchandise if they are dissatisfied. While some categories such as electronics have specific return windows, Costco’s overall return policy remains among the most generous in retail.
For members, that creates an extra layer of confidence.
If a product is recalled because of a safety concern, Costco makes the refund process straightforward. But even when there’s no health or safety issue, the company generally makes returns easy.

The latest milk recall serves as a reminder that no retailer is immune to product issues. It also highlights why Costco’s limited-selection model is so important.
Product quality issues are a rarity at Costco, and that’s something that can’t be said across most retailers.
