The level of histamine and tyramine was determinated in hundred thirteen samples of fish and fish products in correlation with microbiological quality. Most of the examined samples of fish and fish products were characterized by low content of the studied amines. In none of the samples studied, histamine level exceeded the limit of 20,00 mg/100 g, accepted by food law. The maximum level of histamine was 8,00 mg/100 g. Brine with 16% salt concentration did not prevent herring from an increase in the number of bacteria, observed during the first week of storage both at room temperature and +4°C. Amine levels increased proportionally to the duration of storage. High - salted herring preserved good microbiological quality even during storage at room temperature. Amine levels did not increase. It seems important to consider the level of tyramine, since tyramine content may increase the of food-born diseases.
