[Presence of antibiotics in pasteurized milk distributed in Costa Rica hospital nutrition services].
Two hundred samples of pasteurized milk collected from nutrition services of ten hospitals in Costa Rica, were evaluated for the presence of antibiotics residues. Bacterial inhibitory growth test were used to detect inhibitory substances. It was found that 13% (N = 200) of the samples were contaminated, with variations from 0% to 35% (N = 20) in the different hospitals tested. The larger number of positive samples corresponds to lactic industries that supply 70% of the hospital's requirements of pasteurized milk.
