A study from the Journal of Agricultural and Food Chemistry reveals that a single glass of milk can contain traces of 20 painkillers, antibiotics and growth hormones. Although the doses of the drugs were too small to have any affects on milk drinkers, the mere existence of so many different types offers a window into milk production across the food chain. The researchers analyzed 20 types of cow's, goat's and sheep's milk purchased in Spain and Morocco; the highest quantity of medicine was found in cow's milk.
Some of the chemicals found included niflumic acid (painkiller), florfenicol (antibiotic) and 17a-ethinylestradiol (steroid hormone). Click here to see the list of the other chemicals found.
