It now appears that food outlets in the South Auckland suburb of Clendon are not the source of a typhoid outbreak in the area.
Earlier this month health officials investigated four retailers for links to several cases of the disease but tests on 26 workers came up negative.
Dr Greg Simmons of the Auckland Regional Public Health Service says based on what he has seen, it is unlikely the infection is water or food-borne and is likely to be transmitted from person-to-person. Investigations are continuing.
Dr Simmons says the symptoms of typhoid can take three months to show up, so anyone suffering nausea, headaches or vomiting should see their GP.
