FOOT AND MOUTH
* Points to consider in the prevention, control and eradication of FMD
Rationale risk management for the prevention, control and eradication of FMD must be carried out on science-based risk assessments. Presently, the discussion on "to vaccinate or not to vaccinate", and its consequences for international trade, relates to the fact that vaccinated animals may - like convalescent or subclinical infected animals - become (virus) carriers.

* Recently DEFRA published a report of a Cost/Benefit Analysis (CBA) of different Foot and Mouth Disease (FMD) control strategies.
The report notes the advantages of a stand-still of livestock movements, an immediate national movement ban and swift implementation of the revised contingency plan when FMD is first detected. The report also suggests that vaccination reduces the size and extent of medium and large outbreaks - although at an additional financial cost in all but the largest outbreaks.
