Authorship SCIMAGO INSTITUTIONS RANKINGS

ABSTRACT

The M1 aflatoxin (AFM1) has been detected in milk from animal fed with feed contaminated by aflatoxin B1 (AFB1) contaminated. This toxin is a possible carcinogenic to humans (2B class). This is a potential public health problem, because young individuals are among the greater milk consumers and more sensitive to it effects. This study was developed to determine AFM1 in pasteurized milk in same regions São Paulo state. Forty-three samples colected in several cities were analized. The method used for the M1 aflatoxins purification was the immunoafinity column, with subsequent detection by reverse phase HPLC. AFM1 was detected in 17 (39.5%) out of 43 samples, 64.7% of the contaminated samples were above 0.5 µg/L
