The Biocheck.UGent biosecurity scoring system ( is a risk-based scoring system to quantify the on-farm biosecurity (Laanen et al., 2010; Gelaude et al., 2014; Ghent University, 2015). It does not start from a specific disease but rather approaches biosecurity in general and focuses on those aspects that are common for the transmission of many different types of infectious diseases.
The surveys are divided into several subcategories for internal and external biosecurity, and every subcategory consists of 2 to 19 questions. Most questions have two or three answer options. The answer to every question results in a score between zero (when this measure is not implemented at all or the least optimal answer is given) and one (when the measure is fully implemented). Depending on the importance of a particular biosecurity measure, the score per question is multiplied by a weight factor. The weights per score are determined based on the 5 principles of biosecurity.
Also, the subcategories have a specific weight factor equal to their relative importance for disease transmission as determined by a large group of specialists. As such, the Biocheck.UGent scoring system provides a risk-based score which takes into account the relative importance of all different biosecurity measures. The final score for both internal and external biosecurity can range from zero, indicating a total absence of the described biosecurity measures, to 100, indicating a full application of the described measures. The average of internal and external biosecurity results in a score for the total biosecurity. the report you obtain will also include a table with your results, a world average and a country average if there are more than 40 entries for your country.

The Biocheck.ugent scoring system is totally free for use
