About BSE

BSE is a progressive, fatal disease of the nervous system of cattle. The disease has a long incubation period (average of four to five years) and there is currently no treatment or vaccine for the disease.

BSE is one of a group of diseases known as transmissible spongiform encephalopathy (TSE). Other TSEs include scrapie in sheep, chronic wasting disease (CWD) in deer and elk, and Creutzfeldt-Jakob disease in humans.

BSE is a disease for which the OIE established official recognition of the sanitary status countries and zones.

The science-based standards, guidelines and recommendations issued by the OIE are designated as the international reference. The OIE through its experts and world network of Reference Laboratories and Collaborating Centers provides policy advice, strategy design and technical assistance for the control and eradication of BSE.
