Salting of dry-cured meat – A potential cause of contamination with the ochratoxin A-producing species Penicillium nordicum
Penicillium nordicum is a known contaminant of protein-rich foods and is primarily found on dry-cured meat products. It is an important producer of the mycotoxin ochratoxin A, which has nephrotoxic and cancerogenic activities. Recently a high number of P. nordicum strains was isolated from different...

Penicillium nordicum is a known contaminant of protein-rich foods and is primarily found on dry-cured meat products. It is an important producer of the mycotoxin ochratoxin A, which has nephrotoxic and cancerogenic activities. Recently a high number of P. nordicum strains was isolated from different dry-cured meat products from one of the Slovenian meat-processing plants. Since we have isolated P. nordicum in high counts also from Artic habitats, such as sea water and sea ice and due to its ability to grow well at low temperatures and at increased salinity, sea salt was suspected as the possible source of P. nordicum. In the present study contamination of meat products, air in the meat-processing plant and sea salt used for salting were analysed.
