## Executive Summary
Santa Clara County officials are conducting an unprecedented door-to-door search for recalled Costco grapevines to stop a dangerous invasive pest.

## Intelligence Brief
Local officials in Santa Clara County, California, have initiated an unprecedented door-to-door search to recover recalled grapevine plants purchased from Costco locations. According to reporting from outlets including The New York Times, the Los Angeles Times, SFGATE, NBC Bay Area, and The Mercury News, the targeted effort seeks to locate approximately 1,100 vines that were sold to consumers. The operation centers on retrieving these specific agricultural items before they can pose a broader biological threat within the region, specifically targeting potential vulnerabilities near South Bay wineries. Coverage across multiple publications, such as Fox Business, Newsweek, USA Today, inc.com, and MyNorthwest.com, emphasizes that Costco issued warning notices regarding the plants.


These notices alert customers that recently purchased plants, including grapevines and desert willows, may be infested with dangerous, invasive pests tied specifically to California vineyards. Additional reports from KIRO 7 News Seattle, The Cool Down, and the Red Bluff Daily News highlight the involvement of regional agencies working to collect the recalled merchandise and manage the unfolding agricultural situation. Background provided in the coverage explains that the core of the concern is the glassy-winged sharpshooter, an invasive insect known to threaten California's wine industry. Official communications from Santa Clara County and articles by the New York Post detail how this insect is linked directly to the plants distributed through the retail chain.


The proximity of these sold plants to vital agricultural regions and local vineyards creates the immediate need for the retrieval efforts currently underway in San Jose and surrounding areas. Looking ahead, coverage does not yet specify whether all 1,100 vines have been successfully recovered or what additional measures officials might take if any plants remain unaccounted for. Observers and residents are advised to monitor updates from local county departments and official announcements from participating news organizations to track the ongoing collection progress and any further recalls issued by the retailer.
