Investigations of organochlorine residues in breast milk have been conducted
during 1980, 1983, and 1985-86 by the Department of Agriculture in Thailand.
The samnples were colLctcd from lactating mothers in hospitals and analyzed for
residues on a whole milk basis. The first batch of samples were analyzed only
for residues of DDT, whereas the second and third studies included more
organochlorine pesticides. The mean values of pesticide residues in breast milk
for 1980, 1983, and 1986 are shown in Table 4. The levels of organochlorine
residues from the three surveys remained about the same. Reports of work done
by scientists from different countries such as the United States, Australia,
France, Germany, Japan, lndia, Uruguay, and Costa Rica (Currie et al. 1979) on
breast milk samples have also shown similar pesticide residue levels.
