A national control strategy only affects the proportion of meat that
originates from the domestic production. Therefore, the effect of interventions
will not target all broiler meat available for consumption
and accordingly, the direct impact on human cases will be less distinct
than if all meat was domestically produced. The case-by-case
initiative targeting also imported meat was therefore essential in trying
to cover all meat available for consumption in Denmark. It should
be kept in mind that the action plans initiated in the Danish broiler
production are on a voluntary basis so consistency in complying
with interventions cannot be strictly assumed.
