Ochratoxin A in artisan salami produced in Veneto (Italy).

Fifty samples of artisan salami purchased in Veneto (Italy) were analysed for the determination of ochratoxin A (OTA). The analytical method, based on a sample preparation procedure with immunoaffinity columns (IACs), together with analysis by high-performance liquid chromatography with fluorescence detection (HPLC-FD), has guaranteed a high rate of recovery (about 97%), limit of detection (LOD) and limit of quantification (LOQ), respectively, of 0.06 µg kg(-1) and 0.20 µg kg(-1). OTA was detected in five samples, but only one exceeded the guideline value (1 µg kg(-1)) established by the Italian Ministry of Health for pork meat and derived products. The results would seem to suggest that salami made with the traditional, non-industrial production method can be considered safe as regards contamination by OTA. However, the very high concentration observed in one sample proves that a high OTA contamination is also possible in this type of product. Thus, the controls of mycotoxin contamination must consider also salami.
