An investigation on the presence of mycotoxin patulin was performed on 71 apple juices and concentrates and 21 infant fruit purees purchased from retail outlets or producers in Tunisia, by reversed-phase high-performance liquid chromatography using a C-18 column with UV detection at 276 nm, keeping the recovery higher than 96% for spiking levels ranging between 30 and 100 ppb. The detection limit of the method was found to be 5 ppb. The findings showed that 12% of the samples locally produced in Tunisia were contaminated by patulin, with a maximum level of 6 ppb, and 5% of the samples imported and marketed in Tunisia were contaminated at a mean level less than 6 ppb. No detectable patulin contaminations for apple cider and infant fruit puree samples were found.
