Human Salmonella isolates, 2021 No.09, September
The number of isolates (n=40) confirmed this month showed a decrease in comparison to the number of isolates confirmed in September 2020 (n=63). Salmonella Typhimurium ST19 (14.3% in September 2020 vs. 27.5% in September 2021) was the most common serotype confirmed this month. Uncommon serotypes confirmed this month were Salmonella Orion (14 human cases since it was first confirmed in New Zealand in 1993) and Salmonella Uganda (21 human cases since it was first confirmed in New Zealand in 1994).
Due to COVID-19 effect on overseas travel and habits of the community post lockdown, there has been a downturn in the number of Salmonella samples.
