There’s a reason Costco will pretty much let you return any item at any time without a hassle.Costco has built its reputation on offering high-quality products at competitive prices, backed by strict supplier standards and careful product selection. The company knows its products have been vetted to meet certain standards, and that commitment to quality is the key to retaining members. So if there’s a product that doesn’t meet expectations, Costco will take it back.But even a retailer known for rigorous quality controls isn’t immune to product recalls.Last month, Costco warned customers not to consume the Lactantia UltraPur 2% 20g Protein & Lactose Free Milk it sold due to higher-than-intended levels of vitamins A and D.Now, Costco shoppers are facing another recall, this time involving a popular seasonal purchase that carries a very different kind of threat.Costco shoppers warned about recalled grapevine plantsCostco has recalled grapevine plants sold at several Bay Area locations after officials determined they could spread a destructive agricultural pest, SF Gate reported.The recall stems from concerns that the plants contain the glassy-winged sharpshooter, an invasive insect that spreads Pierce’s disease, which can destroy grapevines.The Santa Clara County Division of Agriculture said it will collect the problematic plants from customers who bought them at Costco.Related: Costco makes a silent gas change that members will loveOver 1,300 grapevine plants were sold to customers by Costco in Santa Clara County, and as of July 13, 1,180 of them remained unaccounted for.“If you purchased one of these grapevine plants, we ask that you participate in this collection effort. By allowing us to safely collect and dispose of the plants, you’re helping protect local vineyards, farmers, backyard gardens, and the overall health of our local agricultural economy,” said Priscilla Yeaney, agricultural commissioner for the County of Santa Clara. California’s wine industry contributes $73 billion annually to the state’s economy, according to the Wine Institute, making efforts to contain plant diseases particularly important. Even home gardeners who unknowingly plant infected vines could contribute to the virus’s spread if the disease reaches nearby vineyards or other grape-growing operations.

Costco’s recall system is designed to move quicklyCostco has earned a reputation for responding rapidly when recalls occur. Because the warehouse retailer requires membership for purchases, it can often identify customers who bought recalled products using purchase records tied to membership accounts. Costco frequently contacts affected members directly, making it easier for shoppers to learn about potential hazards than at many traditional retailers.More Retail:Costco sees major shift in member behaviorRetail chain shuts all locations as legal changes hit industryCostco makes major investment in online shopping for membersThat said, quality issues like this are rare at Costco for one big reason. The company’s extensive use of its private-label Kirkland Signature brand gives Costco greater oversight across much of its product assortment. By working closely with a smaller group of suppliers, Costco can exercise more control over manufacturing and sourcing than retailers that rely heavily on hundreds of competing national brands.Another key part of Costco’s strategy is limiting the number of products it sells. While a typical supermarket may stock tens of thousands of individual items, Costco intentionally carries a much smaller assortment of around 4,000 SKUs (stock keeping units).That allows buyers to focus more closely on supplier relationships and product quality.This approach doesn’t eliminate recalls entirely, as both last month’s milk recall and the current grapevine recall demonstrate. But it can reduce the frequency of product issues and allow the company to respond more efficiently when problems arise. That gives Costco yet another edge over its competition and explains why so many customers continue to renew their memberships at astounding rates.Maurie Backman owns shares of Costco.Related: Big changes could be in store for Costco
