Determinación y cuantificación de los niveles de aflatoxina en huevos de consumo.

In this investigation the concentration of aflatoxins B1, B2, G1 and G2 was determined in egg-laying hens commercialized at the Bazurto Market of the Cartagena city (Colombia) and it was compared with the maximum values allowed in Colombia. 6 eggs, from randomly chosen main food market of the city and 10 days provided, were analyzed. The analytical technique of high pressure liquid chromatography (HPLC) was used to determine the content of aflatoxins. The presence of aflatoxins G1 (0.27 a 0.76 ppb) and G2 (25.49 a 125.67 ppb) in some samples of the eggs were detected and amounts remains of aflatoxin B1 and B2 were not found. The amounts of aflatoxin G2 exceeded the permitted values in NTC 3581 in most samples. [ABSTRACT FROM AUTHOR]
