Antimicrobial resistance is expected to make many more victims in the future than cancer, which requires constant, rigorous and thorough control of all factors that contribute to the growth of this particularly worrying phenomenon. Animal products and in particular milk, especially the one obtained in the households of the population, could be especially contaminated with antibiotic residues. The present paper aims at the qualitative and quantitative screening of 284 samples sold by individual producers from the entire territory of Romania, in a period of 3 months (January-March this year). The qualitative test was a microbiological test in tubes with spores of Geobacillus stearothermophilus. 6.33% (n = 18) of the samples confirmed positively in the qualitative test, the quantitative test performed using chromatography showed the presence of beta-lactams and tetracycline in quantities exceeding the maximum residue limit (MRL), (21, 50 μg / kg milk for penicillin and on average 115 μg / kg milk for oxytetracyclines). Among aminoglycosides, gentamicin was on average 294.5 μg / kg milk far exceeding the MRL.
