Microplastic contamination was found in fish and chicken bought on the market, in food stores and in chain supermarkets in the Middle East with the contamination ranging from 0.03 ± 0.04 to 1.19 ± 0.72 particles per gram of meat in chicken and from 0.014 ± 0.024 to 2.6 ± 2.8 particles per gram in fish. Only one fish was found to be free of microplastic. The source of the microplastic was established to be the polythene-based plastic cutting board the food was cut on. More microplastic contamination was found in food cut from the bone than in cut fillets when the fillets themselves were prepared on surfaces other than plastic. Washing the fish and chicken before food preparation decreased but did not completely remove the microplastic contamination. The fate of the microplastic in grilled fish was studied. The mechanical properties of typical plastic cutting boards commercially used in the markets were investigated in the form of tensile, hardness, and wear tests. Overall, the plastic cutting boards showed similar wear rates.
在中东的市场、食品店和连锁超市购买的鱼类和鸡肉中发现了微塑料污染，鸡肉中的污染程度为每克肉 0.03±0.04 至 1.19±0.72 个颗粒，鱼类中的污染程度为每克 0.014±0.024 至 2.6±2.8 个颗粒。只有一条鱼没有发现微塑料。微塑料的来源被确定为食物切割用的基于聚乙烯的塑料砧板。当鱼片本身是在塑料以外的表面准备时，从骨头上切下的食物比切好的鱼片含有更多的微塑料污染。在准备食物前清洗鱼类和鸡肉可以减少但不能完全去除微塑料污染。研究了烤鱼中微塑料的命运。以拉伸、硬度和磨损试验的形式研究了市场上常用的典型塑料砧板的机械性能。总的来说，塑料砧板的磨损率相似。
