“…Celik et al [38] have reported the average Cd content in sardines to be well below these limits (0.002 mg/kg). However, in canned sardines, this metal was above the limit of 0.1 mg/kg [16,21], according to Ashraf et al [32], Tüzen and Soylak [22] and Tarley et al [3]. For canned bonito marketed in Turkey, the concentration of Cd has been reported as 0.06 mg/kg [22], but this metal was above the limits in bonitos caught in the Black Sea [11].…”

“…On the Polish market, mercury contamination of the most popular varieties of canned fish [14] and heavy metals in canned sprat [15] were low in relation to permissible limits. Likewise, canned fish do not present a health risk regarding mercury levels on the Slovenian market [16]. Tuna fish from the Persian Gulf area of Iran [1] and from the Mediterranean coast of Libya [17] have heavy metal concentrations well below permissible levels.…”

Concentrations of selected metals were determined using ICP-MS in canned bonito, sardines and mackerel commercialized in Turkey. Thirty samples and two different brands were sampled for each fish species. The minimum and maximum concentrations of trace metals in canned bonito, sardines and mackerel were found as 0.000-34.742, 0.000-89.015, 0.000-28.725 mg/kg for iron, 2.388-26.620, 10.930-41.340, 4.778-29.270 mg/kg for zinc, 0.331-1.548, 0.599-2.242, 0.336-2.884 mg/kg for copper, 0.000-0.065, 0.000-0.113, 0.000-0.115 mg/kg for cadmium, 0.000-0.190, 0.000-0.158, 0.000-0.385 mg/kg for tin, 0.000-0.111, 0.000-0.223, 0.000-0.208 mg/kg for mercury and 0.000-3.046, 0.000-2.875, 0.000-3.529 mg/kg for lead, respectively. These levels are similar those found in other studies. Although the samples have concentrations within permissible limits for Zn, Cu, Sn and Hg, some of them contained Fe, Cd and Pb above these limits. Periodical controls of metals in canned fish are essential both to protect human health and to provide data on this subject.

“…In a recent article, Miklavcic et al 38 described PCB levels in fish marketed in neighboring Slovenia and, as compared with the tolerance limits recommended by the US Food and Drug Administration, those levels did not represent a health risk for humans. Measurement of PCBs in samples of fish marketed in Italy or in biological samples of a subset of our cohort could help determine if PCB exposure was an issue in this population.…”

BackgroundMercury is a neurotoxin, and limited prenatal exposure to it can affect long-term child neurodevelopment. However, results of epidemiologic studies of such exposure have been inconsistent. We examined the association of prenatal mercury exposure from maternal fish consumption with child neurodevelopment in northern Italy.MethodsA population-based cohort of 606 children and their mothers was studied from pregnancy to age 18 months. Mercury levels were measured in maternal hair and blood during pregnancy and in umbilical cord blood and breast milk. Levels of polyunsaturated fatty acids (PUFAs) were measured in maternal serum. Maternal and child intakes of fish were assessed by using a food frequency questionnaire. The Bayley Scales of Infant and Toddler Development, Third Edition (BSID-III) was used to evaluate child neurodevelopment. Multivariate linear regression was used to examine the association of mercury exposure with BSID-III scores, after controlling for maternal fish intake, PUFAs during pregnancy, and several other confounders.ResultsMean weekly fish intake during pregnancy was less than 2 servings. Mercury concentrations in biological samples were low (mean, 1061 ng/g in hair) and moderately correlated with fish intake, particularly of carnivorous species. Maternal ω-3 PUFA concentrations were poorly correlated with fish intake. Maternal intelligence quotient (IQ) and child intake of fish were significantly associated with neurodevelopment scores. In multivariate models, the level of Hg exposure was not associated with neurodevelopmental performance at 18 months.ConclusionsIn this Italian population, neurodevelopment at 18 months was associated with child intake of fresh fish and maternal IQ rather than with mercury exposure. The expected beneficial effect of maternal fish intake (from maternal ω-3 PUFAs) was not found.

“…However, beside the positive effects on human health, heavy metals, dioxins, PCB's and other contaminants in fish have been discussed for a long time and resulted in the question whether consumption of fish is beneficial or not [2][3][4][5][6][7][8][9][10].…”

“…Therefore in many countries, there have been market studies in order to evaluate the presence and level of contaminants in order to be able to give consumers recommendations [4,6,9,11,12]. In general the levels of the analyzed contaminants as for example heavy metals, PCBs and dioxins were below the restriction levels both in the US [12] and in EU [4,6,9,13,14].…”
