A group of Spanish-Moroccan scientists - from the universities of Córdoba and Jaén, in Spain, and Abdelmalek Essaadi, in Morocco - has devised a new method capable of detecting up to 20 drugs -antibiotics, antiseptics, anti-inflammatories-, in the milk of cow and goat, and also in breast milk.

The new technique will detect contaminants before milk enters the food chain

The director of the study, Evaristo Ballesteros, explains that they have analyzed 20 samples of cow's milk, goat's milk, and several women who have voluntarily participated in the study, using this new method, and who have been able to observe that the concentration of medicines varies According to the type of milk, and that which contains the highest amount of drugs is whole cow's milk, especially niflumic acid, mefenamic acid and ketoprofen (which are anti-inflammatory), and 17-beta-estradiol (a hormone). Niflumic acid and flunixin have also been detected in goat's milk, and the breast milk analyzed included anti-inflammatories -such as naproxen and ibuprofen-, triclosan -an antiseptic-, and certain hormones.

Although the data obtained with this study, published in Journal of Agricultural and Food Chemistry, they are based on a small number of samples and, therefore, it is not possible to extrapolate them to the rest of the milk, the researchers assure that the technique used for the analysis is very sensitive and precise and, as the UJA has informed in a press release. , hope that it will facilitate the task to the laboratories that inspect the quality of the food, and allow them to effectively identify these contaminants, in milk or in other products, before they enter the food chain. This will serve to guarantee the consumer that the food, in addition to having good organoleptic properties and being economical, is harmless and is "free of toxic residues," said Ballesteros.
