Young livestock increase risk of catching disease
There were two infectious disease notifications in the South Waikato during August.
In one incident an adult male contracted Yersiniosis, a disease which is commonly associated with wild pigs.
The possible sources of infection are farm and rural water supplies or contact with wild boar.
The other incident involved a child infected with Giardiasis, which is commonly spread through faecal matter.
South Waikato District Council environment group manager Sharon Robinson said the possible sources of infection were farm and rural water supplies or contact with faecal matter (baby farm animals, general farm activity).
She also confirmed that numbers of infectious diseases in September were trending at five cases.
‘‘There is always a spike in infectious diseases in spring time across New Zealand.’’
In the South Waikato about 90 per cent of all infectious diseases each year occur during spring.
Each incident is reported to the Department of Public Health.
Mrs Robinson said spring infection rates were primarily because of calving because there was more contact between households and baby farm animals.
‘‘A secondary factor can be heavy rainfall. During periods of normal rainfall faecal matter lying on the surface leaches slowly into the ground over time; during periods of heavy rainfall this faecal matter either enters the water table more quickly and in higher concentrations, affecting groundwater, or farm contours can mean that faecal matter can run closer to homesteads where children play.’’
