In order to ensure that the self-management practice for controlling residual pesticides on agricultural products was implemented by the supermarket and hypermarkets, an annual monitoring program was performed. A total of 252 samples, including 217 vegetable, 31 fruit and 4 other samples, were collected from 64 packing firms which supplied products to the supermarkets and hypermarkets. All products were analyzed for 196 pesticides. Among them, 239 samples complied with the regulation, whereas, the rest 13 samples were found containing pesticides which were not allowed for use on each detected product category. Results of this monitoring were released to the public on the Consumer Protection Website of the Department of Health.
