Biosecurity in the agribusiness sector is an often neglected and forgotten area of biological and chemical security. Complicated world environments and fast developing science and technologies especially those in agribusiness sector have put security education and training up to a higher level of importance and therefore building up capability in training in this sector is an urgent but challenge work. In this paper, we firstly present the potential biosecurity issues in agribusiness sector and then address the gaps in biosecurity education in this sector and explore how to build up capability through collaborative works. Through using biosecurity training as a conceptual model to be replicated for chemical and radiological education in agribusiness, we hope to potentially work towards a general framework, so that this capacity can be integrated into building up an International Biological Security Education Network (IBSEN) to tackle other CBRN issues in general.
