“Organic milk is superior to conventional milk, as the cows won’t typically be on an antibiotic, growth hormone, and GMO corn feed diet; they will likely be grass-fed and graze freely.” – L Garber
With the aid of innovative and highly sensitive testing, Spanish-Moroccan scientists determined that there could be up to 20 painkillers, antibiotics, and growth hormones in a single glass of milk. The researchers say that the traces are so small that consumers need not worry about adverse effects, so we’ll just have to take their word for it, it seems.
The scientists analyzed 20 samples of milk—cow’s, goat’s, and human—bought in Spain and Morocco, and found a chemical cocktail of ingredients added to the animal’s diet prior to milking or contamination through feed or on the farm. Some of the contaminants found in trace amounts include triclosan (an anti-fungal), 17-beta-estradiol (a sex hormone), and florfenicol (an antibiotic).

Advances in Food Safety
University of Jaen’s Dr. Evaristo Ballesteros marveled over their technique, which could be used to assess the food safety of other products. “We believe the new methodology will help to provide a more effective way of determining the presence of these kinds of contaminants in milk or other products.”
