Mollusc diseases may
have a very serious effect on the shellfish
industry. An outbreak of such diseases can take
on epizootic proportions, causing mortality and
disturbances on a scale liable considerably to
reduce the profitability of shellfish farming.
It is therefore necessary to establish at
Community level the measures to be taken in
case of outbreaks of disease, in order to
ensure rational development of shellfish
farming and to contribute to the protection of
animal health in the Community.

and the movement into and out of the farm.
Directives 91/67 , 93/53 and 90/70 will be merged and updated by Directive 2006/88/EC of 24 October 2006 on animal health requirements for aquaculture animals and products thereof, and on the prevention and control of certain diseases in aquatic animals. Member States shall apply Directive 2006/88/EC from 1 August 2008.
