For example, antibiotic residues were detected in 60% of conventional milk samples and none of the organic samples.
Milk is an important part of the human diet. But, not all milk is created equal.
A study conducted by researchers at Emory University, Atlanta, in collaboration with The Organic Center, Washington, D.C., found that a majority of samples of conventional retail milk tested positive for residues of antibiotics – two of which are banned from dairy production -- and used controversial pesticides. Meanwhile, organic milk showed no such contaminants. Residues of growth hormones in conventional milk were 20 times higher than in organic, according to the study, “The Benefits of Organic Dairy.”
