R-24-26-Burkholder Inviting conversation on a daunting topic: The role of microplastics in microbial safety of marine foods

Microplastics are ocean pollutants that reach high concentrations in bivalve shellfish, such as oysters. Pathogens in ocean water can attach to buoyant microplastics, and microplastics may aid microbial entry into marine foods. This study will compare microplastic loads in oysters reared in traditional plastic netting versus plastic-free gear, and examine the effects of microplastics on pathogen entry into oysters. Findings from this study will help to inform best practices in bivalve shellfish cultivation and will aid in future strategies aimed at protecting microbiological safety of marine foods.
