Canine tapeworms which have sheep as their intermediate host can be responsible for unpredictable significant economic losses for individual farms. In addition one of these dog-sheep tapeworms, Echinococcus granulosus, is zoonotic, causing cystic echinococcosis in humans which can be fatal. Given that detection of a problem is often only achieved at post-mortem abattoir inspection, reactive control measures are necessarily limited. The aim of this article is to illustrate how the principles of the HACCP (Hazard Analysis and Critical Control Points) system, which is widely used in the food industry, can be used to identify proactive control measures. The role of the small animal veterinary surgeon in control is also discussed.
