Heavy metal contamination, microbiological spoilage and biogenic amine content in sushi available on the Polish market

Popis výsledku v původním jazyce

BACKGROUNDThe present study determined the heavy metal contamination (mercury, cadmium, lead, arsenic and nickel) of nori, restaurant-served sushi and ready-to-eat sushi meals available via retail chains. Moreover, both microbiological load and biogenic amine content in ready-to-eat sushi meals were analysed. RESULTSAll of the nori samples contained high levels of Cd (2.122mg kg(-1)), Ni (0.715mg kg(-1)), As (34.56mg kg(-1)) and Pb (0.659mg kg(-1)). The studied sushi samples contained high levels of Ni and Pb, reaching 0.194 and 0.142mg kg(-1) wet weight, respectively, being potentially hazardous to women during pregnancy and lactation and small children. None of the studied samples contained high levels of Hg. Overall, 37% of ready-to-eat sushi meals exceeded a microbiological load of 10(6)cfu g(-1). However, biogenic amine content in all of the samples was low, with a highest histamine content of 2.05mg kg(-1). CONCLUSIONSushi is not the source of high levels of biogenic amines even with high microbiological loads. Nevertheless, the high microbiological loads at the end of the shelf-life indicate that some processors might have problems with the distribution chain or implement a poor hygienic regime. Moreover as a result of possible risk associated with heavy metal contamination, the present study highlights the need to establish new regulations regarding the contamination of nori and sushi.
