Secretion of TCDD in milk and cream following the feeding of TCDD to lactating dairy cows

This study has shown that the level of TCDD secreted into milk and cream are such as to suggest that the residue found is proportional to the TCDD diet level and to the fat content of the milk or cream. After TCDD is removed from the diet the amount of TCDD secreted into milk decreases with time having a half-life of 41 days.
