Data Breach Summary
Monterey Mushrooms, LLC has reported a cybersecurity incident involving unauthorized access to its computer network, exposing sensitive personal information of at least one individual. The company has begun notifying affected parties and offering free identity protection services.
Monterey Mushrooms, LLC — one of the largest mushroom growers in North America recently confirmed a data breach impacting personal information stored on its computer systems. The incident came to light after the company detected suspicious activity on its network, prompting an immediate response that included securing its IT environment, launching an internal investigation, and notifying law enforcement.
According to official disclosures, the investigation determined that between August 2, 2025, and August 7, 2025, an unauthorized actor accessed certain files stored on Monterey Mushrooms’ servers. These files contained sensitive personal data, including names and Social Security numbers. In some instances, the breach also involved driver’s license or passport numbers. The company completed its review of affected files on August 30, 2025, and confirmed the exposure of this private information.
Though the breach appears to have impacted only one known New Hampshire resident to date, the seriousness of the data involved cannot be overstated. Even limited exposure of Social Security or passport numbers can significantly increase the risk of identity theft.
Monterey Mushrooms has since implemented new security measures to protect its network from future attacks. In addition, they’ve retained the services of Epiq to offer one year of free identity monitoring and recovery support through Privacy Solutions ID. Impacted individuals were notified via U.S. First-Class mail on September 18, 2025.
