(Wageningen Academic Publishers, 2018-05-15)The occurrence of two Alternaria mycotoxins, alternariol (AOH) and alternariol monomethyl ether (AME) and the presence of conidia from Alternaria spp., were investigated throughout the food production chain of two businesses, ... -
Occurrence of selected viral and bacterial pathogens and microbiological quality of fresh and frozen strawberries sold in Spain
(Elsevier, 2019-10-23)Strawberry production and exports have been increasing in Spain in recent decades. However, little information is available about their microbiological quality. Due to the growing concern about the microbial safety of these ... -
Ochratoxigenic moulds and effectiveness of grape field antifungals in a climatic change scenario
(Wiley, 2012)BACKGROUND: The presence of ochratoxin A (OTA) in grapes and grape derivatives has been reported mainly in the Mediterranean area. Consequently, great efforts are being made to prevent the growth of Aspergillus on grapes. ... -
Ochratoxin A and its metabolite ochratoxin alpha in urine and assessment of the exposure of inhabitants of Lleida, Spain
(Elsevier, 2011)Ochratoxin A (OTA) as well as its metabolite ochratoxin α (OTα) were detected in human urine in order to assess the exposure to OTA of a group of 72 adult inhabitants of the city of Lleida (Spain). Urine samples were ... -
