“…According to Taha´ n, et al (1995), the pH of the canned product, the quality of the lacquer coatings of canned products, oxygen concentration in the headspace, quality of coating and storage place may also control metal levels in canned fishes. The results obtained for manganese in canned fish studied was comparable with the results obtained by Ikem and Egiebor (2005) which ranged from 0.01 -2.55µg/g and lower than the corresponding maximum level reported for canned sardines in Brazil (15.77 µg/g: Tarley et al, 2001). United States National Research Council has recommended safe and adequate daily intake levels for manganese that range from 0.3 to 1 mg/day for children up to 1 year, 1-2 mg/day for children up to age 10, and 2-5 mg/day for children 10 and older (Institute of Medicine, 2003).…”

The concentrations of Pb, Zn, Fe, Cd, Mn and Hg in 46 canned fish samples of nine different brands purchased within Kumasi in the Ashanti Region of Ghana were determined using the Flame Atomic Absorption Spectrophotometer for Pb, Zn, Fe, Cd and Mn and direct mercury analyzer (DMA) for Hg. The ranges obtained for the elements analyzed in µg/g (wet weight) are as follows: Pb (0.058 -0.168), Zn (0.010 -0.370), Hg (0.088 -0.410), Mn (0.001 -0.057), Fe(0.990 -32.607) and Cd, below detection limit in all the samples. The fish samples had Hg levels below the European dietary limit of 0.5 µg/g. Zinc levels were generally below the Food and Agriculture Organization (FAO) recommended limit of 40 µg/g. The concentration of lead in the canned fish was also below the MAFF guidelines of 2.0 µg/g. Also, based on the United States Environmental Protection Agency (US EPA) health criteria for carcinogens, there are no health risks associated with Pb concentrations in canned fishes analyzed. The result of the one-way analysis of variance (ANOVA) conducted on the data suggested no significant variations (P>0:05) in the concentrations of the metals in the same brands of canned fishes.

“…The results showed that the mean concentrations of Cr in canned fish with an average of 2.66 ± 0.73 µg/g were much lower than the MPL. The maximum value of Cr in canned fish samples (3.24 µg/g wet weight) we obtained was higher than values obtained for canned fish (0.06 µg/g w.wt) in the USA (Ikem & Egiebor, 2005), and in canned sardines in Brazil (1.11 µg/g w.wt) (Tarley, Coltro, Matsushita & de Souza, 2001). In another study, Hussein and Khaled (2014) reported that the mean concentrations of Cr in muscle of three tuna species from Alexandria, Egypt were 0.82 ± 0.07 µg/g w.wt.…”

Samples of some popular brands of canned Thunnus albacares; Clupeonella cultriventris caspia; Euthynnus affinis; and Thunnus tonggol in the Iranian market were analyzed for determination of Cr, Cu, Fe, Mn and Ni after digestion with 10 ml of 1 N nitric acid by inductively coupled plasma-optical emission spectrometer. The results showed that the concentrations of metals (µg/g wet weight) with an average of 2.66 for Cr, 0.92 for Cu, 54.68 for Fe, 0.33 for Mn and 0.22 for Ni were lower than the Maximum Permissible Limits (MPL) established by WHO. Also, The Health Risk Index (HRI) values were within the safe limits (<1), and there is no potential health risk for adults and children via consumption of canned fish. Despite the fact that our canned fish samples does not significantly contribute to total body burden of analyzed metals, But due to the increased discharge of pollutants into the environment, especially the marine ecosystem, and consider that various species of fish retain substantial amounts of heavy metals during their lifespan, the monitoring of heavy metals concentrations in food is important. Therefore, the study of heavy metal distribution on a temporal basis is recommended.

“…The range of iron levels of muscles of fish between 59.6-73.4 µg/g [24], 68.6-163 µg/g [25], 30-160 µg/g [26] for muscles of fish from the Mediterranean Sea, the Black and Aegean Seas and the Black Sea coasts, respectively. Besides, the range of iron levels in canned sardines marketed in USA and Brasilia have been reported to be 4.83-29.2 µg/g [23] and 21.0-88.8 µg/g [27], respectively. Iron PTWI value is 5600 mg kg−1 body weight per week according to the Joint Expert Committee on Food Additives of the FAO and WHO [14].…”
