Microplastics are a contaminant of global concern and, as such, there has been a rush to action and publication. Over the past decade, this haste has resulted in a chaotic and cluttered literature that is rife with inappropriate methodologies, unrealistic experimental protocols, misinterpreted results, and overstated significance. A comprehensive critical assessment of the current literature on interactions between particle-feeding molluscs and microplastics and their purported impacts (> 600 publications) has been published. It is not surprising that microplastics have been noted in shellfish globally. What is surprising is the extremely low level of particles routinely. The data clearly demonstrate extremely low numbers of microplastics in bivalve molluscs. The literature  literature on interactions and impacts of microplastic on bivalves is seriously flawed, and there are no unequivocal data demonstrating that their presence in bivalve molluscs is a serious risk to human health and few data to demonstrate negative impacts on the shellfish. Editors of scientific journals must make a stronger effort to engage qualified peer-reviewers and stop the flow of poorly done studies and superficial reviews that do nothing more than confuse the literature and reinforce prior inadequate studies and potential reviews.
