ABSTRACT Plastic litter in the oceans is a major environmental problem, and small size plastics (microplastics) have been detected in many species of fish and shellfish consumed by humans. The purpose of this paper is to evaluate the knowledge on microplastics in fish and shellfish in relation to a possible threat to seafood safety. In fish and crustacean species, the presence of microplastics has in most cases been investigated and detected only in the gastrointestinal tract, which is commonly not eaten, and when present, only a very small number is usually found. Bivalves are probably the main source of microplastics when consuming seafood. Preliminary assessments have suggested that the contribution of hazardous chemicals from microplastics for top consumers of bivalves is very small compared to other sources. From the current knowledge on microplastics in seafood, there is no evidence that the safety of such highly recommended food is compromised.

鱼类和贝类中的微塑料——对海鲜安全的威胁？

摘要 海洋中的塑料垃圾是一个主要的环境问题，在人类食用的许多鱼类和贝类中都检测到了小尺寸塑料（微塑料）。本文的目的是评估有关鱼类和贝类中微塑料对海产品安全可能构成的威胁的知识。在鱼类和甲壳类物种中，在大多数情况下，仅在胃肠道中检测到微塑料的存在，而胃肠道通常不被食用，如果存在，通常只发现很少的数量。双壳类动物可能是食用海鲜时微塑料的主要来源。初步评估表明，与其他来源相比，来自微塑料的危险化学品对双壳类动物的顶级消费者的贡献非常小。
