“…Eight of the 15 values were statistically determined as outliers; i.e., Mercury (1), Cadmium (4) and Lead (3). Flores et al (2018) has reported issues in some canned and fresh tuna samples with cadmium content in fresh tuna, but their sample universe was only 36 samples. When higher than standard limits are detected the INP labs proceed as referred in Material and methods section.…”

“…All the samples contained only white muscular tissue (fresh loins); the muscles tend to accumulate the highest concentrations of these metals ( Bosch et al., 2016b ; Al-Najjar et al., 2018 ; Ruelas-Inzunza et al., 2018 ). Since no differences has been found between canned and fresh tuna regarding Cd ( Flores et al., 2018 ), therefore, the study of canned and pre-cooked loins samples would represent fresh tuna loins as well.…”

Tuna species: Skipjack ( Katsuwonus pelamis ), yellowfin ( Thunnus albacares ) and bigeye ( Thunnus obesus ) are mainly processed into canned products (loins, solid pack, flakes) either in water or oil, and pre-cooked frozen loins. The National Institute of Fisheries of Ecuador (ISO/IEC 17025 certified), which is the official control laboratory, samples and analyses production batches of companies exporting to the European Union in order to ensure the quality control of Ecuadorean tuna product. From 2009 to 2016, 2572 samples have been analysed (by standard methods) for mercury, cadmium, and lead. The averages were 0.24 ± 0.14; 0.03 ± 0.03 and 0.05 ± 0.05 mg kg −1 (wet weight) respectively; which are well below the norms; i.e., total mercury: 1 mg kg −1 ; Lead: 0.3 mg kg −1 and Cadmium: 0.1 mg kg −1 according to the EU maximum limits. Over time mercury levels in the sample seemed to decrease but for cadmium and lead no clear pattern was observed. Additionally; samples of tuna can products taken at random from local vendor stores gave concentrations of: Mercury: 0.043 ± 0.004 mg kg −1 ; Cadmium: 0.012 ± 0.002 mg kg −1 ; Lead: below detection limit (0.01 mg kg −1 ). There were a few cases (15 out of 2572: 0.58%) of samples with readings near or just over-limit concentrations; of these, 12 corresponded to Cd, two to Pb and one to Hg. Some of them can be considered statistical outliers as well as cross contamination during analytical procedures. Raw tuna samples have given similar or lower concentrations. No significant statistical correlation was found between Hg, Cd and Pb values, this would suggest that the bioaccumulation of each metal is independent of each other. Literature reports that surface dissolved Hg, Cd, and Pb in the eastern Pacific are in the range of 2–18 ng kg −1 . Assuming suggested bioaccumulation of 2–6 times, the end concentration in the tuna would be 0.012–0.042; 0.036–0.108 and 0.010–0.027 μg kg −1 of Hg, Cd, and Pb respectively, that would be one order (or more) below the safe consumption limit. Most, if not all the tuna processed in Ecuador is captured in the eastern Pacific and within its EEZ. Ecuadorian canned tuna complies with stringent standards for presence of these metals; therefore, it can be considered safe to be consumed from the point of view of these metal concentrations. However, further studies should assess metal concentrations exclusively from Ecuadorian tuna captured close to coastal and insular areas.

El objetivo del presente estudio fue determinar la presencia de metales pesados y determinar las concentraciones de cadmio y mercurio en conservas de pescado enlatadas y se compararon con valores máximos permitidos por el Servicio Nacional de Sanidad Pesquera (SANIPES). Las muestras fueron recolectadas del mercado central del Cercado de Lima. Los análisis fueron realizados por espectrofotometría de absorción atómica con horno de grafito y con generador de hidruros. Los resultados obtenidos fueron: las concentraciones de mercurio superan en 12%, siendo la concentración mayor de 0.65 ppm a comparación de SANIPES 0.5 ppm. Para cadmio superan en 23% siendo la concentración mayor de 0.16 ppm a comparación del límite máximo permisible por el Servicio Nacional de Sanidad Pesquera (SANIPES) de 0.1 ppm.

Se determinó la concentración de Cd en el hígado y músculo de Guanchiche (H. microlepis) y Dica (Pseudocurimata bolengeri). La concentración del metal en el tejido muscular de ambas especies fue menor al límite de cuantificación del método (<0,014 mg/Kg). La mayor concentración de Cd en hígado se observó en la especie P. boulengeri (0,63±0,188 mg/kg) y la menor concentración en H. microlepis (0,003±0,036 mg/kg), existen diferencias significativas en la concentración de Cd de los hígados de ambas especies (F= 33,74; p= 0,000). Letras diferentes indican diferencias significativas según ANOVA de una vía y test a posteriori de Tukey (p<0,05). La concentración de Cd en hígado se encontró por encima del límite máximo permisible (0,05 mg/Kg) establecido por la Unión Europea. La correlación entre peso y talla fue directamente proporcional entre si (r=0,963;p=0,000) la concentración de Cd en hígado fue inversamente proporcional a la talla y peso y la madurez sexual se presentó directamente proporcional a la concentración de Cd (r=0,880; p=0,000).
