When determining which are the salmonella serotypes with public health significance to which Community targets will apply, account must be taken of the following criteria:
the most frequent salmonella serotypes in human salmonellosis on the basis of data collected through EC monitoring systems;
the route of infection (that is, the presence of the serotype in relevant animal populations and feed);
whether any serotype shows a rapid and recent ability to spread and to cause disease in humans and animals;
whether any serotypes show increased virulence, for instance as regards invasiveness, or resistance to relevant therapies for human infections.
