A study has been made of the organochlorine pesticide residues in hens' eggs produced in battery, deep-litter and free-range systems. Low residues (less than 0.05 ppm) were found except where the birds or their houses had been deliberately treated with pesticides to eradicate fleas or lice. A separate study was also made of eggs produced in houses which had insecticide thermal vaporisers installed in them.
