It has been known that AFM1 present in raw milk may be passed to the both cheese curd and whey during cheese production (Galvano et al., 1996). As seen on Table 1. 56% of total AFM1 in raw milk contaminated with 1.5 μg/kg AFM1 (RM-1.5) remained in CHS-1.5 curd while its 31.6% transferred to whey (WHY-1.5). Similarly, 59.1% of total AFM1 in raw milk contaminated with 3.5 μg/kg AFM1 (PM-3.5) remained in cheese curd while its 31.8% transferred to whey (WHY-3.5). Thus, whey contained lower concentrations of AFM1 than the cheeses.
