Salted fish is a common food type in Egypt that is consumed in certain occasions and celebrations. The manufacture process of the salted fish allows fermentation of different fish species. Therefore, there is a high chance for microbial growth and multiplication on such rich protein substrate, and decomposition of the amino acids to their biogenic amines (BAs) derivatives. This study was undertaken to estimate the formed BAs in three salted fish retailed in Egypt, named feseikh, sahlia, and salted sardine. In addition, microbial counts including total plate counts (TPC), total psychrophilic counts (TPsC), and total Staphylococcus aureus counts (TSC) were enumerated. Dietary intakes and health risks associated with the formed BAs were also calculated and discussed. The obtained results revealed formation of the BAs in all examined salted fish species. Feseikh had the highest BAs contents as well as microbial counts. In conclusion, although the calculated dietary intakes revealed no potential risks associated with the consumption of the salted fish, however this assumption should be handled carefully due to inter-individual differences in their immune-reactions to such BAs, particularly histamine.
