Changing ocean conditions are increasing the prevalence of Mud Blister Worms (MBWs) (Polydora spp.) in aquacultured Pacific oysters across the Pacific Northwest, including Washington, Oregon, and Northern California. The presence of these worms in oyster shells can jeopardize their marketability, making it crucial to understand the perceptions of consumers, industry professionals (such as restaurant purchasers and wholesalers), and oyster growers regarding MBWs. While previous research has shown that MBWs do not render oysters unsafe for consumption, this understanding is not widely recognized by the general public, posing marketing challenges for oyster growers amid rising MBW populations. This study analyzed surveys and interviews with individuals, professionals, and growers, offering valuable insights into the perceptions held by these three groups toward MBWs in Pacific oysters from the PNW.
