Both aflatoxins adhered to the milk clot, with a recovery of 102%
for AFLAM1 in this fraction, when the control sample was coagulated.
A recovery of 100 and 111% was obtained for AFLAB1 and AFLAM1,
respectively, in the spiked sample clot. These results reinforce the
importance of establishing maximum permitted levels for dairy
products obtained by milk coagulation. They also highlight the
necessity of a rigid control of raw materials, considering that
currently the Brazilian legislation establishes only a maximum
tolerable limit for AFLAM1 in cheese (2.5 mg kg1).
Deveci [25] quantified AFLAM1 during the production and
storage of canned white cheese from milk samples spiked with the
mycotoxin in two concentrations (1.5 and 3.5 mg kg1). For both
concentrations, after the cheese was produced, about 60% of the
AFLAM1 remained in the clot cheese, while close to 30% was
transferred to the milk serum.
