A glass of milk contains more than 20 analgesic chemicals

A new study by Spanish and Moroccan scientists shows that a glass of milk may contain a mixture of up to 20 analgesics, antibiotics and growth hormones.

With a highly sensitive test method, the international team discovered a range of chemicals used to treat human and animal diseases in cows, goats and breast milk samples.

The highest dosage of drugs is found in cow's milk. Scientists believe that some growth drugs and stimulants have been introduced into cattle or added to milk through feeding cows or poisoning on farms.

According to the Daily Mail, the team analyzed 20 samples of cow's milk purchased in Spain and Morocco along with many samples of goat milk and human milk. Analysis results reveal that cow's milk contains anti-inflammatory substances such as niflumic acid, mefenamic acid and ketoprofen - commonly used drugs such as human and animal painkillers.

Cow's milk also contains 17-beta-estradiol, a form of estrogen sex hormone. This type of hormone is detected at a dose of 3 millionths of a gram in every kilogram of milk. Meanwhile, the highest dose of niflumic acid in cow's milk is 1 millionth of a gram in every kilogram of milk.

The team also found traces of niflumic acid in goat milk and a small dose of ibuprofen and naproxen analgesics, as well as triclosan and some other hormones in breast milk. However, scientists reassure that the doses of these chemicals are very small and difficult to affect anyone who drinks milk.

The team found that the results from milk samples analysis in Spain and Morocco could be similar when testing the milk produced in England and northern Europe. This study provides another powerful demonstration for the presence of artificial chemicals in all foods.
