Sheep ingest tapeworm eggs from the pasture, these eggs can survive on pasture for up to six months but most eggs are no longer viable at four months, length of egg survival is highly dependant on the environment.
The eggs if swallowed by a sheep, hatch in the intestine and the larvae migrate More
Of all the control measures for prevention of sheep measles regular dog treatment is the most reliable and the most simple (and probably the cheapest) measure to implement. Dog treatments and dosing should be the basis of any on-farm control programme More
Because sheep of all ages can be infected with sheep measles cysts, all sheep (and goat) meat should be treated before feeding to dogs. Sheep meat treatment can be done in one of two ways – by freezing or cooking. More
Home killing of stock is common on many farm properties to provide meat for human consumption on farm as well as for dog food. To prevent dogs gaining access to raw sheep meat or offal at the killing site, these procedures should be followed:
Dead stock attracts stray or unattended dogs that could scavenge on carcasses. Dispose of all dead animals as soon as practicable.
• Carcasses can be buried. If a pit is used, it should be covered or fenced to ensure it is dog proof. More
Uncontrolled or unsupervised dogs are a sheep measles risk if they scavenge on dead sheep who may be infected with the sheep measles. If they continue to roam they will contaminate sheep pastures. Dogs do not respect boundary fences and a stray dog has the potential to infect many surrounding properties. Recommendations to assist with effective dog control include: More
Foreign or external dogs pose a risk to any on- farm programme in place. Unless you are aware of their status in relations to Sheep Measles treatment all foreign dog should be deterred or the person in control required to show some evidence of treatment for sheep measles. More
Introducing store sheep including lambs is another means of bringing Sheep Measles infection onto the farm. As it is not possible (short of a blood test) to detect Sheep Measles in live stock it is a case of buyer beware!! In relation to Sheep Measles, store lambs fall into two categories: More
Hydatid is the cystic, larval stage of the tapeworm Echinococcus granulosus, Hydatid has a lifecycle similar to that of sheep measles: hydatid is found in farm livestock (including sheep) and even humans, while the adult tapeworm occurs in dogs (the parasite’s primary host). Unlike, sheep measles, hydatid is a public health issue. More
Request that new dogs being purchased have a current certificate or are treated with a cestocidal drug at least 48 hours prior to being introduced onto the property. If new dogs enter property without being treated beforehand, they should be dosed and quarantined for 3-4 days and all faeces buried or destroyed. More
