Data underlying the publication Development and implementation of a risk assessment tool for broiler farm biosecurity and a health intervention plan in the Netherlands, Greece, and Cyprus

Introduction Preventing pathogens from entering and spreading on farms is the first step in reducing health problems.<br> For this study a BiosEcurity Assessment Tool was developed to identify strengths and weaknesses in biosecurity on broiler farms,<br> which was used as a starting point to formulate tailor-made health plans to improve broiler health and reduce antimicrobial use. Measurements and data collection Farms were divided into 3 separate areas according to associated biosecurity risk; high disease risk external areas (red zone), medium risk service areas (orange zone),<br> and the clean and highly secure access-restricted green zone. In the Netherlands, Cyprus, and Greece, 13, 15, and 7 broiler houses were monitored for 4 production cycles (2 preintervention and 2 postintervention cycles).<br> At the start of the study the BiosEcurity Assessment Tool assessment was performed and a health plan was made in consultation with the veterinarian.<br> After the second cycle a start was made with the implementation of the health plan.
