London, July 6 (IANS) Scientists have developed a method that helps in simultaneous detection of 20 kinds of contaminants in milk from humans, cows and goats.

 
 These three kinds of samples showed that they all contain antibiotics, anti-inflammatories, antiseptics, lipid regulators, beta-blockers and hormones, although the largest number of drugs was found in whole cow milk.
 
 The method was developed by researchers at the universities of Jaén and Córdoba in Spain and the Abdelmalek Essaadi University in Morocco.
 
 "We used this methodology to analyse 20 samples of cows' milk, goats' milk and breast milk from human volunteers," said Evaristo Ballesteros, researcher at the University of Jaén, the Journal of Agricultural and Food Chemistry reports.
 
 "We found that the drug content differs according to the type of milk," said Ballesteros, who also led the study, according to a Jaen statement.
 
 Human milk too contained anti-inflammatory drugs (such as ibuprofen and naproxen), as well as the antiseptic triclosan and some hormones.
 
 The scientists believe the new methodology will help provide a more effective way of determining the presence of these kinds of contaminants in milk or other products.
