Sreening of mycotoxins in tomatoes, onions, bell peppers, soft red fruits and derived tomato products with LC-TOF-MS

Abstract
Risk assessment studies and legislation are available for multiple mycotoxins such as aflatoxins, ochratoxin A, deoxynivalenol, zeoralenone, fumonisin, T-2 and HT-2 toxin in cereals, maize and dried plant products (e.g. nuts, spices and dried fruits) (1). Also, patulin in apple and apple products is widely documented (2). However, limited data are available for mycotoxins associated with fresh produce and their derived products. Recently, EFSA published a report on the status of fresh produce and possible mycotoxins (3). It indicates the need for further research on hazard identification and risk assessment studies. A multi screening method was developed with LC-TOF-MS to screen moulded fresh produce (tomatoes, onions, sweet bell peppers and soft red fruits) from different countries (Belgium, Spain, India, Brazil, South Africa, Egypt) for the presence of a multitude of mycotoxins possibly associated with fresh produce (alternariol (AOH), alternariol monomethyl ether (AME), ochratoxin A (OTA), fumonisins (FB1, FB2, FB3)). In total 320 moulded products were investigated. AOH and AME was found in all four types of fresh produce (respectively 30 and 25% prevalence). Fumonisins and ochratoxin A seems not to play a major role as a mycotoxin hazard, with exception of FB2 in moulded bell peppers from India. In total 173 samples of derived tomato products (such as ketchups, concentrates, dried tomatoes) were screened. AOH and AME were respectively found in seven and five derived tomato products (concentrates and purees). The presence of these Alternaria mycotoxins in both fresh produce and derived food products urgents the need for a dietary exposure risk assessment, with quantitative mycotoxin concentration data and consumption data.
