Antibiotics have been found in most foods
Widespread use of antibiotics in human healthcare and livestock husbandry has led to trace amounts of the drugs ending up in food products.
The Authors said that consuming these foods over a long period of time could lead to increased antibiotic resistance of bacterial pathogens or to an imbalance in the gut microbiome.
The examination included store-bought samples of wheat flour, mutton, eggs, milk, cabbage and bananas and detected a total of 10 antibiotics. One of them, roxithromycin which is a semi-synthetic macrolide antibiotic used to treat respiratory tract, urinary and soft tissue infections which is derived from erythromycin.
