Abstract

In order to determine the residue levels of organochlorine insecticides in cow's milk, 66 commercial milk samples were collected from markets in major cities of Korea and analyzed for their fat contents and pesticide residue levels. The fat contents were in the range of $2.65{\sim}3.87%$, the average being 3.35%. The average residue levels of organochlorine insecticides on fat basis (whole milk basis in parentheses) were 0.196 ppm (0. 0066 ppm) of ${\alpha}-BHC$, 0.159ppm (0.0055 ppm) of ${\beta}-BHC$, 0.066 ppm (0.0022 ppm) of heptachlor epoxide and 0.042ppm (0.0015 ppm) of DDE. Heptachlor, DDT and drin insecticides were not detected. These residue levels corresponding to $1/10{\sim}1/50$ of tolerance levels adopted in Japan appear to exhibit no adverse effect as yet from the standpoint of food safety.
