摘要：The Communicable Disease Control Branch of the South Australian Health Commission received 45 laboratorynotifications of Salmonella between 23 December 1996 and 17 January 1997. A rapid screening test, undertakenby the Institute of Medical and Veterinary Sciences, Adelaide, was the first indication that this was more thanone outbreak, prompting the establishment of separate investigations. Three Salmonella Typhimurium (S.Typhimurium) phage types were subsequently identified. Investigations are continuing into an outbreak of S.Typhimurium phage type (PT) 64, while investigations failed to identify any association between four cases ofPT 44. As of 12 February 1997, 71 notifications had been confirm ed as S. Typhimurium PT 135. Epidemiologi-cal investigations found this outbreak was associated with co nsumption of bread r olls with a meat fillingdistributed through local Asian grocery stores from a home-based manufacturer. The product was voluntarilywithdrawn and there have been no new cases of PT 135
