The objective of this study was to quantify lead and cadmium in chicken gizzards sold at the Caquetá Market – San Martín de Porres during the period from October to December 2014. Thirty chicken gizzard samples were collected from different vendors in the market. The method used for the quantification of lead and cadmium in chicken gizzards was Atomic Absorption Spectrophotometry with a Graphite Furnace. The average lead concentration was 0.630 mg Pb/kg, with extreme values of 0.89 mg/kg, exceeding the maximum limits established by the Codex Alimentarius and the European Union in 87% of the samples. The average cadmium concentration was 0.20 mg Cd/kg, with extreme values of 0.29 mg/kg, exceeding the maximum limits reported in the study from Egypt in 100% of samples and in the Malaysian study in 90% of samples. In conclusion, the analyzed samples contain heavy metals, representing a potential health risk for consumers.

Determinación de plomo, cadmio y arsénico en carne de pollo expendida en el mercado de Caquetá – San Martín de Porres. Lima – Perú. Noviembre del 2020

In this research, lead, cadmium, and arsenic were quantified in chicken meat samples (Gallus domesticus) sold at the Caquetá market, located in the district of San Martin de Porres in Lima, Peru, using atomic absorption spectrophotometry with a graphite furnace and atomic absorption spectrophotometry with a hydride generator. The quantification of the mentioned elements was performed at the Center for Information, Toxicological Control, and Environmental Management Support (CICOTOX). The results obtained were as follows: the average concentration of arsenic was 0.0006 mg/kg, with a minimum value of 0.0001 mg/kg and a maximum value of 0.0027 mg/kg. The average cadmium concentration was 0.02027 mg/kg, with a minimum value of 0.0078 mg/kg and a maximum value of 0.0627 mg/kg. The average lead concentration was 0.6953 mg/kg, with a minimum concentration of 0.3047 mg/kg and a maximum concentration of 1.1953 mg/kg. It is concluded that, in chicken breast meat samples, arsenic values are within acceptable limits; however, both cadmium (8%) and lead (100%) exceed the maximum permissible limit set by MERCOSUR.

Determinación de plomo, cadmio y arsénico en hígados de pollo expendidos en el mercado Caquetá – San Martín de Porres período de marzo–julio 2015

The objective of this study was to quantitatively determine the levels of lead, cadmium, and arsenic in chicken liver sold by poultry vendors at the Caquetá Market during the period from March to July 2015. Samples were collected from 30 poultry vendors, taking one liver sample per vendor, and analyzed using Atomic Absorption Spectrophotometry with a graphite furnace for lead and cadmium. Arsenic was analyzed using Atomic Absorption Spectrophotometry with hydride generation. The results showed that the average lead concentration was 0.4326 mg/kg, below the limits established by Mercosur, the European Union, and the Codex Alimentarius; however, lead concentrations in 7 out of 30 samples (23%) exceeded the established limit. The average cadmium concentration was 0.4403 mg/kg, also below the limits established by Mercosur, the European Union, and the Codex Alimentarius; nevertheless, cadmium concentrations in 10 out of 30 samples (33%) exceeded the established limit. The average arsenic concentration was 0.858 mg/kg, above the limit established by Mercosur, with 7 out of 30 samples (23%) exceeding the limit. In conclusion, the analyzed samples contain heavy metals, posing a potential risk to consumers and representing a threat to public health.
