Abstract
The Biosafety Level 4 Zoonotic Laboratory Network (BSL4ZNet) was established in 2016, to provide a means of communication and support for the global high-containment laboratory community. Its working groups focus on international response, institutional cooperation and knowledge sharing, scientific excellence and training. In the latter role, BSL4ZNet sponsored its first international workshop in February 2018, held at the USDA National Centers for Animal Health, Ames, Iowa, USA, focused on necropsy procedures in high-containment laboratories. A second workshop, in November 2018, was held at the National Microbiology Laboratories (CFIA/PHAC) in Winnipeg, Canada, and focused on decontamination. A third workshop, held at the Australian Animal Health Laboratory in Geelong, Australia, in February 2019, was devoted to handling methods and ethical concerns for live animals in high-containment laboratories. The third workshop brought together 12 laboratorians from seven partner organizations in Australia, Canada, Germany, the United Kingdom and the United States. It included both discussion-based and hands-on training sessions on animal welfare, animal models, site-specific infrastructure constraints, health monitoring and humane endpoints, sampling procedures, and carcass disposal. This report summarizes the inception, development, and structure of the BSL4ZNet, and highlights the aims and results of the Geelong workshop.
