A new method for detecting drugs in dairy-DairyReporter.com

The technique was examined in a recent study, published in the journal of agricultural and Food Chemistry.

Method to identify 20 different drugs in cows, goats and milk, humans, researchers at the University of Córdoba and Jaén Spain and Morocco Abdelmalek Essaadi University, who performed the study.

Technique, researchers analyzed in cow's milk (fresh, whole, semi-skimmed, skimmed and liquid), goat's milk (full skimmed and semi-skimmed) and human breast milk vapaaehtoisilta 20 samples.

Three sets of samples were found to contain milk is anti-inflammatories, they said.

Contains different types of drugs, antibiotics, anti-inflammatories, antiseptics, of a fat content, by the regulatory authorities, beta blockers and hormones in milk varieties.

Technology

The technique uses a "solid phase extraction system of the continuous" and classifies them by using the "gas chromatography mass spectrometry".

"The confirmation of the results clearly show that this method is the most sensitive and one of the most selective, the date in the scientific literature, described in the" said Ballesteros.

"It is also very accurate and precise analysis of the short time (about 30 minutes)."

The Conclusions Of The

It was found that the drug is different from the content of the milk in the form of research, said the Director of Evaristo Ballesteros.

The largest number of pharmacologically active substances found in the size of cow's milk, in particular, the three said the anti-inflammatory drugs; niflumic acid and ketoprofen, mefenamic and hormone 17 beta-estradiol.

Niflumic acid were also found with the fluniksiini goats ' milk.

Analysis of the human milk also contained anti-inflammatory drugs (such as ibuprofen and Naproxen) and no antiseptic Triclosan and some hormones, such as the 17-ethinyl estradiol, Alpha 17 beta-estradiol, and-of Estrone.

Even if the investigation confirms that the method, the results should not be generalised to all sorts of samples, a small amount of milk, the researchers said, due to the.

For future use

Food quality control laboratories to detect drugs, milk or other products in the food chain, a new tool, said the researchers.

"This consumer awareness and provide them with information on food, with the exception of its good organoleptic characteristics and a good value is also harmless, pure, genuine, beneficial health and toxic residues."Source: Journal of agricultural and food chemistry
