Conclusions There are currently a few tools for the biosecurity assessment in farms. These tools rely on qualitative methods, which do not allow to perform a quantitative measure of biosecurity. Introduction Biosecurity on farms is considered essential to prevent the entry and/or transmission of disease, which could negatively affect production. Biosecurity is defined “as the implementation of measures that reduce the risk of disease agents being introduced and spread” (Bottoms, K. et al, 2009). The aim of this work is to review the different tools available for the assessment of biosecurity in farms and see if they fit correctly in the different productions in the world.
