Bovine Spongiform Encephalopathy
BSE, also known as mad cow disease, originated in the UK and is of tremendous concern to the cattle industry. This is a fatal, neurological disorder that is spread by contacting infected central nervous tissue. Cows show neurologic dysfunction and are often dead within 48 hours. There are no ante mortem tests and there is no treatment for this disease. The major scare associated with BSE is that its a zoonotic disease, so it is imperative that infected animals don't enter the food chain.
Foot and Mouth Disease
FMD is a highly contagious viral disease that affects cloven-footed animals. Transmission of FMD is exceptionally fast and can cause devastating losses to producers. Infected animals develop blisters on their mouth and feet and there is a noticeable drop in weight gain and milk production. There is no treatment, but infected animals are usually culled due to the drop in production.
