The improvement of the methodology of assessment of the quality of fish products and ecological state of aquatic ecosystems, used in fish culture, became a priority, according to the standards and directives of EU, UNESCO and FAO, which foresee the adaptation of ISO methods. The elaboration of national schemes of indicators of the quality of fish products, appreciation of the safety of fish products and of their risks for human health is a task of major importance. The quantity of imported fish in Moldova exceeds greatly the quantity of autochthonous, captured and cultured, fish. This fact determined us to perform a screening of the content of metals in fresh and frozen fish products. Samples of fish imported from France, Norway, Greece, Italy, Spain, China, etc. were investigated. In most of cases, the content of metals in imported fish, including of those listed in the Moldovan Sanitary Regulation on the contaminants in food products (Governmental Decision no.520/2010), was higher than that recorded in local, grown in pond, fish. Some concentrations, for example, of arsenic (As – 5.2-7.4 mg/kg) in the European pilchard (Sardina pilchardus), as well in gilt-head (sea) bream (Sparus aurata) and sablefish (Anoplopoma fimbria) (As – 2.8-4.2 mg/kg) were quite high and exceeded the maximum allowable concentrations (MAC) for fish products by 3-7 times. Also, the content of lead in sablefish and yellowfin tuna (Thunnus albacares) exceeded the MAC almost by two times. Of a high concern are the concentrations of bismuth (Bi) found in the Atlantic salmon (Salmo salar) from Norway and gilt-head (sea) bream. The pharmaceutical compounds, which penetrate into waters, may be one of the sources of this metal in fish products. The content of zinc (Zn - 103-134 mg/kg) and chromium (Cr – 6.6 mg/kg) in fish from a range of countries exceed the MAC for fish products.
