Abstract
A study was investigated to estimate the current status of health hazardous organochlorine insecticide DDT and its metabolites DDE and DDD in different species of dry fish. To achieve the goal of this experiment, ten different sun-dried fish samples were collected from different markets of Dhaka city. The concentration of DDT, DDE and DDD was determined using the capillary column coupled to Gas Chromatograph with Electron Captured Detector (GC-ECD). Most of the dry fishes, seven out of ten samples, were found to be contaminated with DDT along with its metabolites DDE and DDD ranging from 0.029-1.22 mg/kg which is a serious concern because of the nature of long persistency and bioaccumulation of DDT in the environment. The highest concentration of DDT (1.22 mg/kg) was observed in Pampus chinensis dry fish whereas low concentration was detected in Otolithoides pama (0.029 mg/kg). Asian Australas. J. Food Saf.

Highlights
Fish drying is a very popular and common practice applied in Bangladesh for preserving fishes that are not instantly consumed or sold in the fresh markets
A slow poisonous organochlorine (OC) pesticide DDT was the first insecticide applied during World War II to control lice and mosquitoes combating typhus and malaria, is applied in dry fishes to control pest infestation and it was reported that this hazardous chemical is transferred from generation to generation through breast milk (Solomon et al, 2001)
The results indicated that DDT was used in controlling and limiting the pest infestation of dry fishes during processing and storage
Summary
Fish drying is a very popular and common practice applied in Bangladesh for preserving fishes that are not instantly consumed or sold in the fresh markets. Dry fish is one of the most popular food items which fulfill the demand of protein of many people in different areas of Bangladesh. It has been reported that fish drier and traders face great challenges during processing and storage of the dry fishes due to rapid moisture absorption which causes the dried fishes more suitable for infestation by different insect pests including beetles and mites. A slow poisonous organochlorine (OC) pesticide DDT was the first insecticide applied during World War II to control lice and mosquitoes combating typhus and malaria, is applied in dry fishes to control pest infestation and it was reported that this hazardous chemical is transferred from generation to generation through breast milk (Solomon et al, 2001). The embryonic and fetal period are appeared as the most vulnerable time of
