In the past decade, the world has witnessed an increasing demand for organic milk, among other products that are made organically. Adding points to that argument, a recent study has discovered that non-organic milk mostly contains the residue of pesticides, antibiotics and growth-hormones that were used at different levels of the milk production process. Organic milk, however, does not show this problem.
“To our knowledge, the present study is the first study to compare levels of pesticide in the U.S. milk supply by production method – conventional vs. organic. It is also the first in a decade to measure antibiotic and hormone levels and compare them by milk production type,” the researchers have noted in their opinion of the results of the study. That having said, experts believe that the results should be interpreted with caution.
The research was conducted by a group of researchers at Emory University, Atlanta but the funding involved contributions from a non-profit research organization, which goes by the name of The Organic Center. Public Health Nutrition is the name of the journal that published the study. The study was based on 69 non-organic milk samples the team had collected from retail stores across the United States.
The study says that while 60% of non-organic milk products were found to have residue content of the sorts mentioned above, the researchers could not detect their presence in organic milk products. The researchers noted that sulfamethazine and sulfathiazole were two of the major antibiotics, whose residue were found in the milk products.
It is clear that the study is quite limited from many aspects and that it needs further scientific justification. At this point, this cannot be generalized; nor can it be used to state that non-organic milk products cause a lot of problem to the consumers. However, as the researchers themselves believe, it’s a good place to start.
