Cost analysis of various low pathogenic avian influenza surveillance systems in the Dutch egg layer sector.

<h4>Background</h4>As low pathogenic avian influenza viruses can mutate into high pathogenic viruses the Dutch poultry sector implemented a surveillance system for low pathogenic avian influenza (LPAI) based on blood samples. It has been suggested that egg yolk samples could be sampled i...
