The Enteric Reference Laboratory confirmed 117 non-human Salmonella isolates in August 2014 compared with 181 August 2013.
There was a decrease in the number of:
- S. Brandenburg isolates (55 in 2013 versus 45 in 2013)
- S. Montevideo isolates (9 in June 2013 versus 1 in June 2014).

- Bovine isolates (72 in 2013 versus 52 in 2013)
Occurrence of Salmonella Brandenburg infection in humans is a seasonal phenomenon in the southern half of the South Island (Baker et al. 2007 in Epidemiol. Infect. 135(1):76–83) and is often linked with occurrence of the serotype in livestock.
Salmonella Brandenburg has caused periodic epidemics of disease in sheep flocks in Otago and Southland since 1997 see: http://www.stuff.co.nz/business/farming/sheep/9090477/Bacterial-outbreak-killing-South-Island-sheep
