Bovine Spongiform Encephalopathy by Tafara Mapuvire https://padlet.com/tmapuvire/8wfmiluqjvic en-us 2016-12-02 04:19:09 UTC 2016-12-02 05:11:32 UTC hello@padlet.com The Hazard tmapuvire https://padlet.com/tmapuvire/8wfmiluqjvic/wish/141300307 - Bovine spongiform encephalopathy (BSE) is a nervous disease of cattle. It is caused by an agent that differs distinctly from conventional infectious agents.
-Cattle in the UK contracted this disease when carcass meal obtained from sheep suffering from a similar disease (scrapie) was included in their rations. The disease was then propagated by feeding meat and bone meal (MBM) from diseased animals to healthy cattle. It takes years for cattle to show symptoms of the disease.
- The disease is invariably fatal.]]> 2016-12-02 04:36:57 UTC https://padlet.com/tmapuvire/8wfmiluqjvic/wish/141300307 The Risk tmapuvire https://padlet.com/tmapuvire/8wfmiluqjvic/wish/141300431 -The disease was first reported in 1985 in the United Kingdom (UK). Since then more than 
180 000 BSE cases have been confirmed in the UK alone. BSE has also since been reported from other countries. Most of these countries are, however, regarded as low-risk countries because of their strict slaughter-out policy. This disease has never been diagnosed in South Africa or any other country in Africa.
-There are 54 million people in South Africa.
- The cattle population in South Africa is 13.8 million.
-The sheep population in South Africa is 28.8 million
-Entry of BSE into South Africa would cause massive economic losses.
- There is no evidence that cattle can directly infect one another with BSE.
-A definite link between BSE (in cattle) and Creutzfeldt-Jakob disease (in humans) has not been proven. Suspicion of such a link is, however, the cause of worldwide concern.

-Ban on import of cattle, beef and beef products from the UK and any country that cannot prove that it is free from BSE.
-As a further precaution farmers in South Africa are not allowed to feed meat and bone-meal from the remains of cloven-hoofed animals to their livestock.
-Continuous surveillance by veterinary services in South Africa.]]> 2016-12-02 04:53:22 UTC https://padlet.com/tmapuvire/8wfmiluqjvic/wish/141301006 Communication tmapuvire https://padlet.com/tmapuvire/8wfmiluqjvic/wish/141301267 -Liaison between South African veterinary services and the veterinary services of other countries regarding changes in epidermiology of BSE.
-Border agencies to be vigilant and closely monitor imported animals for suspicious clinical signs.
-Communicate import requirements to trade partners.]]> 2016-12-02 04:59:35 UTC https://padlet.com/tmapuvire/8wfmiluqjvic/wish/141301267
