There were 1399 human Salmonella isolates confirmed in 2008 (2007 n= 1341). S. Typhimurium phage type 160 remains the predominant strain, representing 9.7% of total isolates (11.3% 2007). S. Typhimurium phage type 101 and S. Saintpaul have increased to 5% (3.2% 2007) and 2.5% (1.9% 2007) respectively.

There were three significant outbreaks:
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.
