Example of a graph summary from one farms’ hygiene results. The farms’ total score is the bar to the left, and the horizontal lines indicate the assessment limits for hygiene rating. Below 55% (red line) indicates poor hygiene, between 55.1–70% (yellow line) indicates acceptable hygiene and above 85% (green line) indicates excellent hygiene. The diamonds point out the biosecurity areas needing improvement with scores below or borderline to 55% according to assessment scores
