Emerg Infect Dis. 2016 Nov;22(11):1970-1973. doi: 10.3201/eid2211.160210.

Abstract

We conducted a retrospective study of 40 case-patients and 58 controls as part of a nationwide investigation of a group B Streptococcus outbreak in Singapore in 2015. Eating a Chinese-style raw fish dish (yusheng) was a major risk factor for bacteremia, particularly caused by serotype III sequence type 283.

Keywords: Singapore; Streptococcus agalactiae; bacteria; food safety; food-borne infections; group B Streptococcus; outbreak; raw fish; raw foods; sequence type 283; serotype III; streptococci; yusheng.
