Almond production in Portugal is of great importance for the economy of their main producing areas. However, the contamination of these nut fruits with fungi and mycotoxins poses a significant risk to food safety and security. This work intended to evaluate the influence of storage conditions on the microbial and mycotoxin stability and safety of almonds throughout long-term storage. Two almond varieties-Lauran...
Gnomoniopsis smithogilvyi (Gs) is a relevant pathogen of chestnut since it provokes significant losses worldwide. The aim of this study was to screen the effect of a new biocontrol agent (BCA) against Gs isolated from chestnut (CIMO-BCA1) on the mould’s growth as well as on the production of secondary metabolites. The chemical fungicide Horizon® (tebuconazole; HOR) and the commercial biofungicide Serenade® ASO ...

Long-term transport and storage of peeled almonds under unsuitable conditions may cause the product’s rejection. To get knowledge in this topic, peeled almonds were stored at 25◦C and 60, 70, and 80% relative humidity (RH). The maintenance of high RH (80%) caused some visual defects after 4 months. Even though the 60, 70, and 80% RH did not clearly affect the production of primary and secondary products formed ...

Chestnut tree (Castanea sativa Mill) is a crop with high economic and social importance in Trás-os-Montes Region. The pre and post-harvest quality of its nuts can be affected by many factors, being the lasses dueto fungi very large. During the last decade a new endophyte fungus, Gnomoniopsis smithogilvyi, causing brown rot, has been isolated from both rotten and healthy fruits, and its growth seems to be relate...
It has been previously established that rainbow trout are extremely sensitive to the ubiquitous Fusarium mycotoxin deoxynivalenol (DON)
Fungi of the genus Penicillium are promising sources of bioactive substances. Fungal strains isolated from poorly characterized habitais are currently under active investigation as potential producers of biologically active compounds. Penicillium nordicum is mostly known by its ability to produce the mycotoxin ochratoxin A in several protein- and salt-rich food matrices like processed meat and cheese, but it ca...
A multi-mycotoxin method based on High Performance Liquid Chromatography coupled with tandem Mass Spectrometry detection (HPLC-MS /MS) was applied to investigate the occurrence of toxic fungal metabolites in samples collected from a poultry feed factory and integrated poultry farms, in Brazil. A total of 119 samples were analyzed including 38 maize grain samples collected from the factory reception, 36 maize gr...
