Abstract

Residue analyses for insecticides were conducted when whole tomatoes and tomato juice were processed from damaged tomatoes that had been in contact with the surfaces of wooden hampers treated with malathion or diazinon. There were 0.18–0.21 and 0.59–0.64 ppm of malathion in whole tomatoes and juice, respectively. No diazinon residues could be detected in whole tomatoes and only traces in juice. The data show that it should be safe to treat tomato hampers with these insecticides in an attempt to control nitidulid beetles that infest damaged processing tomatoes during the period between picking and delivery to the factory.
