3 February, 2021

The annual report concerning Foodborne Diseases provides annual data on foodborne trends in New Zealand.
Campylobacteriosis: During 2019, 6202 cases (126.1 per 100,000 population) of campylobacteriosis and no resulting deaths were reported. Approximately 9% of cases were recorded as hospitalised in 2019. Of the 702 hospital admissions (14.3 admissions per 100,000 population) recorded in 2019, 582 cases were reported with campylobacteriosis as the primary diagnosis and 120 were reported with campylobacteriosis as another relevant diagnosis.
It has been estimated by expert consultation that 63.8% of campylobacteriosis incidence is due to foodborne transmission. It was further estimated that 75.4% of foodborne transmission would be due to transmission via poultry.
Salmonellosis: During 2019, 1188 cases (24.2 per 100,000 population) of salmonellosis and no resulting deaths were reported. Approximately 23% of cases were recorded as hospitalised in2019.Of the 230 hospital admissions (4.7 admissions per 100,000 population) recorded in 2019, 203 cases were reported with salmonellosis as the primary diagnosis and 27 were reported with salmonellosis as another relevant diagnosis. It has been estimated by expert consultation that 62.1% of salmonellosis incidence is due to foodborne transmission. It was further estimated that approximately 19% of foodborne transmission was due to transmission via poultry.
In 2019, there were 27 salmonellosis outbreak notifications, 15 (56%) of which reported food as a possible mode of transmission. These 15 outbreaks included 186 cases, of which 26 were reported to have been hospitalised. 
In 2019, 1055 isolates from cases with non-typhoidal Salmonella were typed. S. Typhimurium and S. Enteritidis were the most common serotypes identified, of which S. Typhimurium 108/170 (83 isolates), S. Typhimurium phage type 56 variant (49 isolates), S. Typhimurium phage type 101 (36 isolates) and S. Enteritidis phage type 11 (31 isolates) were most commonly detected.
