From April 2002 to March 2008, a total of 122 food samples were examined at the Yokohama City Institute of Health for possible contamination of insects. One hundred and two cases (83.6%) of insect contamination were found, and each case was identified. The insects found in the food samples consisted of 10 orders. Lepidoptera was most dominant (35 cases; 34.3%), followed by Diptera (26 cases; 25.5%) and Coleoptera (19 cases; 18.6%). The insect contamination was found in different kinds of food including box lunches, cooked side dishes, wheat flour, fish, rice, snacks, and sweets. The insect contamination appeared to be introduced in different phases of food processing: in ingredients (25.2%), in the manufacturing process (28%), during transportation or storage (7.0%), and at home (7.8%). The phase of contamination was undetermined for the remaining 36 cases (31%).
