Experts say that although an outbreak of the Schmallenberg virus would be bad news for livestock farmers, it is not nearly as bad as a bluetongue outbreak.
Schmallenberg only causes mild symptoms in adult livestock and affects less than a third of newborn animals.
Bluetongue spread to the UK from the Continent in 2007, and prompted an emergency response of widespread vaccination. There were fears it could have killed 25-30% of the country's sheep.
