Mae'r Gweinidog wedi dod yn Warcheidwad Gwrthfiotigau - rhan o ymgyrch ledled y DU sy'n ceisio annog pawb, o'r cyhoedd i bobl sy'n gweithio ym maes iechyd anifeiliaid a phobl, i wneud gwell defnydd o'r meddyginiaethau hanfodol hyn.
The Minister has become an Antibiotic Guardian - a UK-wide campaign which aims to encourage everybody, from the public to people working in animal and human healthcare, to make better use of these vital medicines.
