S. Chester - 54 cases. The outbreak started in October 2007 with a total of 84 cases.
No food source was linked to this outbreak.
S.Mbandaka - 36 cases. No food source was connected to the outbreak. The results of the case control study however suggested the consumption of chicken breast meat as a possible risk factor.
S. Typhimurium phage type 42 - 62 cases. The majority of these cases were connected to the consumption of raw flour. The same phage type was also isolated from bags of unopened flour and resulted in a voluntary withdrawal of the product by the manufacturer.
