The collection of occurrence data on Alternaria toxins in food and feed across the Europeancountries is required since 2012 by the European Commission, endorsing the relevant scientificopinion by the EFSA CONTAM Panel. Within this framework, occurrence data for Alternaria toxins(Alternariol, Alternariol monomethyl ether, Tenuazonic acid, Tentoxin, and Altenuene) in 97 samplesof cereal foods, tomato products, and sunflower seeds have been provided as requested by theItalian national monitoring programme (years 2017-2020).

Abstract

The collection of occurrence data on Alternaria toxins in food and feed across the Europeancountries is required since 2012 by the European Commission, endorsing the relevant scientificopinion by the EFSA CONTAM Panel. Within this framework, occurrence data for Alternaria toxins(Alternariol, Alternariol monomethyl ether, Tenuazonic acid, Tentoxin, and Altenuene) in 97 samplesof cereal foods, tomato products, and sunflower seeds have been provided as requested by theItalian national monitoring programme (years 2017-2020). To this purpose, an LC-MS/MS methodwas set up and validated, obtaining fit for purpose sensitivity, recoveries (70-120%), repeatability(<=20%) and within laboratory reproducibility (<=26%). Occurrence data showed that oilseeds werethe most contaminated food group with levels of Tenuazonic acid up to 16752 ?g/kg and Tentoxinup to 570 ?g/kg, whereas for the other mycotoxin/commodities combinations, the percentage ofleft censored data (below the limit of quantification) ranged from 74 to 100%.
