Abstract: Food safety has acquired great attention by food importer and exporters. Food rejection or acceptance across international borders is based on the compliance with international food regulations. Due to the lack of recent data on pesticide residues in Mexican grains, this study focused on detecting and quantifying insecticide residues in stored wheat, corn, chickpeas, and beans, as well as to determine their mutagenic potential. Grains were sampled from primary storage sites in Sonora, Mexico. Malathion, chlorpyrifos, deltamethrin, cypermethrin, 4,4-DDE, 4,4-DDD and 4,4-DDT were analyzed in 135 samples. Grain samples were not mutagenic and most pesticide levels were within regulation limits.

Analysis of Eight Organophosphorus Pesticide Residues in Fresh Vegetables Retailed in Agricultural Product Markets of Nanjing, China
TL;DR: A method to effectively remove pigments in fresh vegetables using activated carbon followed cleanup through solid phase extraction (SPE) cartridge to further reduce matrix interference and contamination, was established and has been successfully applied for the determination of eight OPPs in various fresh vegetables with the recoveries ranging from 61.8% to 107%.

Revised methods for the salmonella mutagenicity test
Dorothy M. Maron,Bruce N. Ames +1 more
TL;DR: Two new tester strains, a frameshift strain and a strain carrying an ochre mutation on a multicopy plasmid (TA102), are added to the standard tester set and two substitutions are made in diagnostic mutagens to eliminate MNNG and 9-aminoacridine.

In vitro studies on the genotoxicity of the organophosphorus insecticide malathion and its two analogues.
TL;DR: Malathion used as commercial product, i.e., containing malaoxon and isomalathion, can be considered as a genotoxic substance in vitro and can be regarded as a potential mutagen/carcinogen and requires further investigation.

Modulation of the mutagenicity of heterocyclic amines by organophosphate insecticides and their metabolites.
TL;DR: The mutagenicity of 2-acetoxyacetylaminofluorene (2AAAF) and the heterocyclic dietary carcinogen 2-amino-1-methyl-6-phenylimidazo(4,5-b)pyridine (PhIP) was enhanced in the presence of the OP insecticides, ethyl parathion or methyl parathions or a metabolite (methyl paraoxon).
