In 1978 the following foods, produced and retailed in Hokkaido, Japan, were examined for their content of organochlorine pesticide residues (number of samples in brackets): milk (7), modified dried milk (1), butter (4), eggs (8), chicken (8), beef (2), pork (8) and 10 types of fish (14). The amounts of HCH, DDT and dieldrin in milk and modified dried milk did not exceed 0.004, 0.002 and 0.001 p.p.m. resp. but butter contained 0.056-0.106, 0.010-0.036 and 0.003-0.017 p.p.m. resp. of these pesticides and 0.007-0.010 p.p.m. of heptachlor epoxide. No aldrin, endrin, heptachlor or dicofol (kelthane) was found in any sample. Av. daily intake of HCH, DDT and dieldrin from milk was estimated to be 0.210, 0.053 and 0.053 mu g, and from butter 0.172, 0.050 and 0.019 mu g; estimated intake of HCH and DDT were less than 30% and 20% resp. of 1973 estimates whereas dieldrin intake was unchanged. More than 50% of HCH intake from animal products in 1978 and 39.1% of dieldrin intake, was contributed by dairy products. [For part XII see DSA 42, 7976].
