Calls for farmers to get on top of worm treatment for their dogs - to stop the spread of C-ovis or sheep measles

The Ovis Management Programme reports 1.2-percent of sheep carcasses processed in October were infected - double the standard.

There's no risk to humans, but resulting blemishes in the meat make it undesirable for export.

The programme's project manager, Michelle Simpson, is urging farmers to treat their farm dogs regularly to prevent infections.

She says the higher the prevalence of infections, the higher the risk contaminated meat will reach our markets - meaning people won't want to buy New Zealand sheep meat.
