A rattled Mr Dehaene said: "I am convinced there is no more dioxin in food.

They fed in federal data about each source of dioxin, weather information and details about factors like the chemical reactions that happen to dioxin in the air.
After adjusting for factors like age and body fat levels, they concluded that the Ranch Hand participants with the lowest levels of dioxin in their blood had a 47percentt lower risk of diabetes than those with the highest levels of dioxin in their blood.
