bovine serum albumin (BSA) conjugate as an immunogen. An indirect competitive enzyme-linked
immunosorbent assay was standardized for estimating AFM1 in milk and milk products. To avoid the
influence of interfering substances present in the milk samples, it was necessary to prepare AFM1
standards in methanol extracts of certified reference material (CRM) not containing detectable AFM1
(<0.05 ng/g). The reliability of the procedure was assessed by using CRM with AFM1 concentrations
of <0.5 and 0.76 ng/g. Also, assays of milk samples mixed with AFM1 ranging in concentration
between 0.5 and 50 ng/L gave recoveries of >93%. The relative cross-reactivity with aflatoxins (AF)
and ochratoxin A, assessed as the amount of AFM1 necessary to cause 50% inhibition of binding,
was 5% for AFB1 and much less for AFB2, AFG1, and AFG2; there was no reaction with ochratoxin
A. AFM1 contamination was measured in retail milk and milk products collected from rural and
periurban areas in Andhra Pradesh, India. Of 280 milk samples tested, 146 were found to contain
<0.5 ng/mL of AFM1; in 80 samples it varied from 0.6 to 15 ng/mL, in 42 samples from 16 to 30
ng/mL, and in 12 samples from 31 to 48 ng/mL. Most of the milk samples that contained high AFM1
concentrations were obtained from periurban locations. The results revealed a significant exposure
of humans to AFM1 levels in India and thus highlight the need for awareness of risk among milk
producers and consumers.
