Only one sample of the inner part (4% of examined samples) was positive with a content of 26.6 ppb. A different situation was highlighted for the rind. Eight out of 25 samples were positive (32% of examined samples). The amounts were between 15.4 and 460.8 ppb. Positive samples were confirmed by GC analysis.
29.4 Discussion
As reported, patulin is a mycotoxin produced by several fungal species and was detected in many food items; however, unlike what other authors have found (Erdogan et al. 2003; Kokkonen et al. 2005; Taniwaki et al. 2009), we detected patulin in cheese samples. In particular, we detected patulin in samples taken from the rind. However, when these results are compared with the amounts established as maximum limits by the Reg. 1881/2006 (i.e., from 10 to 50 μg/kg), it is clear that little concern exists for consumer health because the mycotoxin has been detected mainly in the rind.
