LOPEZ, Clara et al. Aflatoxin B1content in patients with hepatic diseases. Medicina (B. Aires) [online]. 2002, vol.62, n.4, pp. 313-316. ISSN 1669-9106.

Aflatoxins are toxic metabolites of some Aspergillus flavus, A. parasiticus and A. nomius strains that occur in many foods and feeds. There are four major natural occurring aflatoxins: B1, B2, G1 and G2. These toxins can cause illness in human beings and animals. Aflatoxin B1 is the most abundant and toxic member of the family, and it is also the most potent hepatocarcinogen known. In order to estimate the potential human health risk of AFB1, it is useful to measure blood concentration. The presence of aflatoxin B1 in patients was evaluated by high-performance liquid chromatography, in serum samples, obtained from 20 patient volunteers with hepatic disease. Out of the 20 patients, the presence of AFB1 was detected in only one of them, in a concentration of 0.47 ng/cm3. Nevertheless, this result should draw the attention of control organizations in Argentina to the need for a thorough food and feed inspection.

Palabras clave : Aflatoxin B1; Hepatic diseases; Serum samples; HPLC.
