Abstract

Over 22 samples of tomato, tomato paste, and ketchup collected from local markets, located in Majmaah Province, Saudi Arabia, were tested for the presence of 412 pesticide residues using the modified QuEChERS method, followed by LC-MS/MS and GC-MS/MS. About eight pesticide residues were detected in 36% of analyzed samples. The amount and frequency of detected pesticide residues were higher in tomato samples. All detected residues were below the maximum residue limits (MRLs). Multiple residues were detected in 27% of analyzed samples. Of the pesticides, cypermethrin was the most detected one followed by carbendazim. The average daily intake and health risk indices for Majmaah region population were estimated. The results showed that consumption of tomato and its products do not represent a risk to human health in this region. However, the presence of multiple residues in some samples necessitates regular monitoring of pesticide residues in tomato crop.
