Three batches of yoghurts were made from goat's milk with different enrofloxacin concentrations (0, 50, 100 and 150 lg/kg). Quality parameters were analysed at 1, 7, 14 and 28 days at 5°C. Drug residues were also quantified by HPLC. Coagulation time and most yoghurt properties remained unaffected by the presence of enrofloxacin in goat's milk. However, quality parameters were affected by the storage period. 74.9-99.2% of enrofloxacin initially added to goat's milk remained in the yoghurt throughout its entire shelf life, potentially posing a risk to consumer health. Therefore, an enrofloxacin maximum residue limit in yoghurt should be established.

“…In addition, drug residues change the raw milk processing qualities by hindering the propagation of starter cultures used for the production of dairy products such as cheese and yogurt [1]. Pasteurization and ultra-high temperature treatment get rid of pathogenic bacteria in raw milk but do not affect to reduce or eliminate residual drugs [21].…”

Abstract:This study was conducted to analyze penicillin G (PEG), streptomycin (STR) and neomycin (NEO) residues in milk of healthy lactating cows. Milk samples were collected from all four quarters of 12 dairy cows 2−7 days after intramammary infusions of an ointment containing PEG, STR and NEO once (n = 4; group I) or twice (n = 4, group II) daily. Ultra-performance liquid chromatography coupled with electrospray tandem mass spectrometry was used to determine the antibiotic residues in the samples. The correlation coefficient (r 2 ) of the calibration curves for all antibiotics was > 0.999 and the limits of detection and quantification were 0.002-0.005 µg/mL and 0.007-0.02 µg/ mL, respectively. Recovery rates were ranged from 75.5 to 92.3%. In group I, PEG, STR and NEO residues were detected in milk at 2, 3 and 2 days post-treatment, respectively, which were below the maximum residue limit (MRL). In group II, PEG, STR and NEO residues were detected in milk at 2, 3 and 3 days post-treatment, respectively, which were bellow the MRL. These results suggest that a 3-day for milk withdrawal period after the ointment treatment might be sufficient for reduction of the antibiotic residues below the MRL.

“…Por um lado, muitos dos agentes antibacterianos utilizados como primeira escolha terapêutica tem perdido a sua efetividade, perante a expressão de diferentes mecanismos de resistência adotados pelos agentes etiológicos da mastite bovina (RUEGG et al, 2015). Por outro lado, o uso de antibacterianos de amplo espectro tem comprometido as características organolépticas do leite, além de gerar resíduos que, direta ou indiretamente, afetam os derivados lácteos e a microbiota de ecossistemas que estão em contato direto com estes resíduos (ADETUNJI, 2011). Assim, estudos que contemplem esta problemática e visem à procura de alternativas de tratamento, são dignos de investigação.…”
