Efforts to eradicate salmonella enteritidis from the poultry industry are on track with no properties under restricted movement controls.
The bacteria strain was first found in an Auckland hatchery in March last year.
Since then 14 sites tested positive for the strain, about 550 thousand birds have been culled and 130 people became unwell with the bacteria.
Salmonella enteritidis can cause abdominal cramps, diarrhoea, fever, headache and vomiting in people.
New Zealand Food Safety deputy director general Vincent Arbuckle said control efforts were paying off.
Salmonella enteritidis had not been detected on farm since early September and the last case detected in a human was May, he said.
“It’s almost a textbook example of the regulator working with the poultry industry and individual farmers, what was a pretty serious outbreak in 2021. Through careful work with the industry, we believe we’ve got a well contained now.
