CJD can occur suddenly without any apparent cause; such cases are called sporadic. The disease may be passed on in families or may be transmitted by contact with contaminated tissue from humans or animals.

First, farmers everywhere must report cattle that show symptoms of Mad Cow disease and to stop importing and exporting meat from infested countries. This is not all, people around the world must also be careful about which foods they eat and how they cook their meat. Also, governments and policy-makers must protect public health by taking known information and design restriction and regulations pertaining to the type of feed cattle intended for slaughtering receive and the meat we receive from foreign countries. Eliminating the main source, sheep and cattle, would be the most practical solution today. A few years ago this might not have been so. There are also other techniques that we can use to test for CJD such as a spinal tap, which can be used to stop the transfer of tainted blood between transfusions (filtered blood). Today, these tactics are the most practical in terms of eliminating the most common type of the disease, new variant CJD.
