A glass of milk can contain a cocktail of up to 20 painkillers, antibiotics and growth hormones, scientists have shown.
Using a highly sensitive test, they found a host of chemicals used to treat illnesses in animals and people in samples of cow, goat and human breast milk.
The Spanish-Moroccan team analysed 20 samples of cow’s milk bought in Spain and Morocco, along with samples of goat and breast milk.
Their breakdown, published in the Journal of Agricultural and Food Chemistry, revealed that cow’s milk contained traces of anti-inflammatory drugs niflumic acid, mefenamic acid and ketoprofen – commonly used as painkillers in animals and people.
