In summary, potential cocktails of contaminants involving
AFM1, PCDD/Fs, PCBs, and toxic metals should be expected in
yogurts, whose combined adverse effects are still quite unknown.
However, yogurts should not be considered as a relevant source of
human health risks, because the pollutant concentrations are
usually low. On the other hand, our comparison between private
label and branded yogurts did not show notable differences in their
nutritional compositions, or in their contamination levels. The
most relevant differences were found in some PCDD/F and PCB
congeners, pollutants that in two private label yogurts were found
at higher concentrations than in the remaining brands. As
conclusion, in the context of the serious current economic crisis,
and based on the results of the present survey, from the point of
view of the nutrients and contaminants here analyzed, the
significant differences among the prices of the BY and
