Abstract

Sweden is investigating an outbreak of monophasic Typhimurium. Eighty-two nationally-distributed cases have been confirmed, with date of symptom onset between 28 August and 29 October. Cases were 51 years of age on average (range: 0–89) and the majority of cases were female (62%). A case–control study was conducted and suggested small tomatoes as source of the outbreak (adjusted odds ratio (OR): 10.8, 95% confidence interval (CI): 4.15-112.68, p value < 0.001), and a trace-back investigation led to a single, non-Swedish producer in Europe. Both the strain and the source of the outbreak are rarely encountered in Europe. Results from investigation at the producer are pending.
