Transmissible Spongiform Encephalopathies
TSEs in animals are a class of rare brain diseases that are associated with the accumulation of abnormal prion protein in the brain and therefore affect the central nervous system. These diseases are very rare, fatal and are characterised by spongy degeneration of the brain. There are no validated live animal tests, no treatments and no vaccines for these diseases.
There are a number of TSEs which variously affect people and animals. Of most interest to Australia's livestock industries are:
- bovine spongiform encephalopathy (BSE) which affects cattle and other ruminants and is commonly referred to as "mad cow disease"
- scrapie, a TSE which affects sheep and goats
- chronic wasting disease (CWD) which is a TSE that affects cervids such as mule deer, white tail deer and Rocky Mountain elk
- feline spongiform encephalopathy (FSE) which is found in domestic cats and captive exotic cats
- transmissible mink encephalopathy (TME) which is a very rare disease of farmed mink
- Creutzfeldt-Jakob disease (CJD) which is a rare and fatal form of TSE that affects humans worldwide. A new form of CJD, called variant Creutzfeldt-Jakob disease (vCJD) was identified in 1996 as the human form of BSE linked to the consumption of certain tissues of BSE-infected cattle.
Bovine Spongiform Encephalopathy
BSE is a progressive, fatal disease that affects the nervous system of cattle.
Australia is internationally recognised as a ‘negligible risk’ country for BSE.
In common with other TSEs, BSE has a typical incubation period of four to six years. Most cases are seen in cattle over four years of age. Signs of the disease can appear gradually, however once clinical signs have appeared the affected animals die within two weeks to six months. There is no fever. Nervous signs are always present, but variable, and can fall into three categories:
- changes in behaviour, such as nervousness, apprehension and frenzy when cattle are confronted by gateways and other obstacles
- abnormal posture and gait, such as staggering, swaying, high lifting of legs when walking, tremors, falling over and being unable to get up when lying down, and
- extreme sensitivity to sound and touch.
A number of proven tests for BSE are available, but not in live cattle. A combination of these proven tests may be used on suspect cases. These include examining slices of the brain through a microscope, with or without staining with special antibodies, and a number of rapid tests which rely on detecting the abnormal protein that accumulates in certain parts of the brain.
The World Organisation for Animal Health (OIE) sets international standards for BSE in the Terrestrial Animal Health Code. The OIE has developed a three category country classification system assessing members as either ‘negligible’, ‘controlled’ or ‘undetermined’ risk countries.
As of September 2009, 11 countries have been assessed as ‘negligible risk’: Argentina, Australia, Chile, Finland, Iceland, New Zealand, Norway, Paraguay, Singapore, Sweden and Uruguay.
As of September 2009, 32 countries have received a ‘controlled risk’ assessment: Austria, Belgium, Brazil, Canada, Chinese Taipei, Colombia, Cyprus, Czech Republic, Denmark, Estonia, France, Germany, Greece, Hungary, Ireland, Italy, Japan, Latvia, Lichtenstein, Lithuania, Luxembourg, Malta, Mexico, Netherlands, Poland, Portugal, Slovak Republic, Slovenia, Spain, Switzerland, United Kingdom and United States.
The OIE also recognises that only certain cattle tissues present a risk of transmitting BSE and recommends that these be removed from cattle from BSE affected countries at slaughter if they are above a certain age. These tissues are tonsils, part of the small intestine, brains, eyes, spinal cord, skull and vertebral column. These OIE recommendations on tissue removal do not apply to Australia.
The OIE BSE standard in the Terrestrial Animal Health Code is available from the
OIE website. A disease card that provides further technical information on the disease is also available from the
Occurrences in Australia
Australia was one of the first countries to implement effective quarantine measures against BSE entering the country (see the section
Australia’s approach to BSE). Australia meets international requirements for a BSE negligible risk country. This has been confirmed by national and international risk assessments, for example those conducted by the Food Standards Australia New Zealand, the New Zealand Food Safety Authority and the European Food Safety Authority. An assessment by the OIE was released in May 2007 and concluded that Australia met the requirements for a 'negligible BSE risk' country.
TME have never been recorded in Australia. Scrapie has occurred once, in imported sheep on a single property in 1952 and was promptly eradicated. Two cases of
FSE have been diagnosed in imported animals in Australian zoos in 1992 (cheetah) and 2002 (Asiatic golden cat). In both cases exposure before importation to feeds derived from BSE affected cattle are thought to have caused the disease. In both instances, effective response measures were taken.
The Global Context - BSE
BSE was first reported in the UK in 1986. It is thought to have originated from the ingestion by cattle of scrapie infected material from sheep, although the original source of BSE infection remains under debate.
Changes in rendering practices that occurred in the UK around 1980 are believed to have allowed increased survival of the BSE agent in meat and bone meal used as an ingredient in cattle feed. In this way the BSE agent was recycled in the UK cattle population. Due to the long BSE incubation period of several years, this recycling continued unabated without obvious clinical signs of disease, eventually leading to the UK epidemic.
Other European countries were also affected, although at a much lower rate than the UK, as a result of importing infected live cattle and stockfeed (meat and bone meal) from the UK. These include Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Ireland, Italy Liechtenstein, Luxembourg, the Netherlands, Poland, Portugal, Slovakia, Slovenia, Switzerland, Spain, and Sweden.
A series of countermeasures were introduced by the UK and other countries to break the cycle of cattle re-infection. These measures included a ruminant protein feed ban as well as bans on importation of live cattle and ruminant protein from infected countries. The feed ban helped to reduce the BSE epidemic in Europe, with the numbers of
BSE cases there tailing off after 2000. This evidence suggests that BSE may eventually be eradicated. Outside of Europe, other countries that have diagnosed indigenous cases of BSE include Israel, Japan, Canada and the United States. Again, these cases can be linked to the importation of cattle and/or meat and bone meal from Europe.

International BSE incidences
OIE Terrestrial Animal Health Code (the Code) aims to assure the sanitary (disease related) safety of international trade in land based animals and their products. This is achieved through the detailing of health measures to be used by the veterinary authorities of importing and exporting countries to avoid the transfer of agents pathogenic for animals or humans, while avoiding unjustified sanitary barriers. The
Code Chapter on BSE details international standards for measures used in preventing the trade related transfer of BSE between countries.

Australia’s Approach to BSE
For beef producing countries such as Australia, the issues surrounding BSE are highly significant. Australia currently meets international criteria for a BSE negligible risk country, and this can only be assured by continuing to apply vigorous risk reduction measures, verified by an ongoing surveillance program. Through the government/industry Transmissible Spongiform Encephalopathy Freedom Assurance Program (TSEFAP), these processes are well coordinated, nationally uniform, transparent and auditable in order to demonstrate BSE freedom and maintain access to export markets for cattle, beef and by-products.
The Australian Government recognises that despite the best efforts to exclude serious animal diseases such as BSE, it is possible incursions could occur. Preparedness arrangements for large scale responses to emergency animal diseases are therefore a key element in Australia’s defences. Through the Council of Australian Governments, Australia’s preparedness to mount an effective, whole of government animal health response has been reviewed and upgraded. Furthermore, these arrangements are tested by disease simulation exercises to ensure a high level of preparedness.
How could BSE be introduced to Australia?
Key factors in the epidemiology of BSE are well established. These factors point to three main pathways for the possible introduction of the BSE disease agent to a country’s cattle herd.
Importation of certain animals from TSE-affected countries
Live cattle cannot be imported into Australia from BSE affected countries. The cattle that are still alive from the limited number of previous imports have been permanently identified utilising the National Livestock Identification Scheme (NLIS). They are also in official ‘lifetime quarantine’ so that they will never enter the human food or animal feed chains. Risk assessments have shown that there is a negligible risk that BSE was introduced into Australia by importation of these cattle. Information on the NLIS can be found at the
Meat and Livestock Australia website.
Importation of contaminated feedstuff originating from BSE affected countries
The importation of animal-derived meat and bone-meal (except for fishmeal) from all countries except New Zealand was banned in Australia in 1966 as a measure against the importation of anthrax spores. Risk based import controls minimise the chance that other imported stockfeeds or stockfeed ingredients have been cross-contaminated with meat and bone meal. Current import policies are detailed on the
Biosecurity Australia website.
Importation of biologicals contaminated with the BSE agent
Quarantine risk assessments have been made of vaccines and other biological materials that involve cattle and sheep products in their manufacture and that are intended for use in animals. Restrictions on the importation of these products have been extended in line with emerging knowledge of the BSE status of countries throughout the world. Current Biosecurity Australia policies are detailed on the
Biosecurity Australia website.
Stringent controls are in place against the introduction of BSE through these pathways. In the unlikely event that the BSE agent is introduced through one of these pathways, the legislated bans in Australia on feeding ruminant animals meat and bone meal derived from mammals, birds or fish (i.e. restricted animal material) will prevent BSE being propagated and amplified.
Transmissible Spongiform Encephalopathy Freedom Assurance Program
Prior to establishment of the TSEFAP, the many animal TSE risk reduction measures in Australia were managed and funded in different ways. The TSEFAP integrates all TSE measures into one national program with clear and nationally integrated operational components and a transparent funding framework. Information on the TSEFAP can be found at the
Animal Health Australia website.
The purpose of TSEFAP is to enhance market confidence that Australian animals and animal products are free from TSEs through the nationally integrated management of animal-related TSE activities. The purpose of the program will be served by meeting the following objectives:
- to carry out sufficient surveillance to meet international requirements and assure trading partners, markets and consumers that Australian animals and animal products are free of TSEs and to ensure the early detection of a TSE (should it occur)
- to demonstrate that no restricted animal material is fed to ruminants
- to manage the risks posed by animals imported from countries that have had cases of TSE
- to provide a nationally coordinated approach to TSE-related research and development
- to communicate Australia's favourable status for TSEs consistently and efficiently
- to ensure Australia is adequately prepared to address any TSE case, should it occur
- to identify emerging TSE-related issues and provide a framework for their management, if required
- to provide a forum to involve all stakeholders in addressing animal-related TSE issues, and
- to increase the efficiency and consistency of management of animal-related TSE activities.
TSEFAP activities fall into six project areas:
- surveillance (the NTSESP and any other required surveillance)
- ruminant feeding restrictions
- imported animal surveillance (including zoo animals) and 'buy-back' schemes for imported cattle
- research and development
- management and coordination, and
In developing the TSEFAP Business Plan, major stakeholders including all agricultural authorities from all Australian Governments, industry bodies representing producers, meat processors and the stockfeed animal feeding industry, and Food Standards Australia New Zealand.
Active surveillance for BSE commenced in Australia in 1990 and was modified in 1998 with the development of the National Transmissible Spongiform Encephalopathy Surveillance Program (NTSESP), which is a core activity of TSEFAP. The primary purpose of the program is to support trade by maintaining a surveillance system for BSE that is consistent with the OIE Terrestrial Animal Health Code, verifying that Australia’s BSE risk reduction measures are effective.
NTSESP is a targeted component of Australia's overall disease surveillance effort. The overall system comprises both general and targeted surveillance. General surveillance comprises a wide range of activities to maintain a continuous watch over the livestock disease profile so that unexpected changes can be recognised. Activities include pre and post slaughter inspection at meatworks, inspection of animals at sale yards and other points of aggregation, farm visits by private and government veterinarians and results from laboratory testing.
Raising local awareness among veterinary practitioners and producers of the need to report nervous diseases in cattle is carried out by government officers, relevant industry organisations and veterinary practitioners. Training of practitioners and government officers includes awareness of BSE and other
TSEs of animals, nature of the diseases, selection of eligible animals as well as specimen collection and laboratory submission to ensure the occurrence of
TSEs in Australian livestock can be ruled out and alternative diagnoses confirmed whenever possible.
Current policies, programs and links to international sites are detailed at the
Animal Health Australia website.
Ruminant Feed Ban
In accordance with a recommendation from the World Health Organisation, a voluntary ban on the feeding of ruminant meat and bone meal to ruminants was adopted in Australia in 1996. This acted as a fail-safe control measure to rule out the possibility that feeding will amplify the BSE agent in the unlikely event that it was introduced to Australia. Laws to enact the ban were introduced in all Australian jurisdictions in 1997. The ban has since been extended to 'restricted animal material', being any meal derived from animal origin including fish and birds. A uniform national approach to official inspection and auditing, coupled with industry-based quality assurance programs and third party audits, verifies compliance with the ban. A number of education initiatives have been undertaken to ensure that all industry segments are aware of their responsibilities. Current policies and programs are detailed at the
Animal Health Australia website.
Imported Cattle Quarantine and Surveillance
Australia suspended the importation of cattle from the UK in 1988 and from other European countries in 1991, and from other BSE affected countries from the date the disease was first reported.
Cattle imported from countries that subsequently have reported BSE cases have been traced, and those remaining alive at the time have been placed under official permanent quarantine in accordance with Section 55A, Regulation 36 of the
Commonwealth Quarantine Act (1908). This section of the Act prohibits the unauthorised movement of cattle, or their sale for slaughter, and ensures that their carcases will be disposed of in an approved manner upon death or destruction. All of these cattle have been permanently identified in accordance with the
NLIS and their details recorded in the NLIS database. These measures allow the normal commercial management of the animals, but prohibit their use for the production of human or animal food.
Some imported cattle were slaughtered before BSE was reported in their country of origin. However, scientific risk assessments have shown that there is a negligible likelihood that BSE became established within the Australian cattle herd as a result of the importation of cattle.
Current policies and programs are detailed at the
Animal Health Australia website.
Memorandum of Understanding (MOU) – National response to a foot-and-mouth disease outbreak PDF [113kb], is the result of an agreement by the Council of Australian Governments that an outbreak of foot-and-mouth disease and its consequences must be managed on a national basis. While this MOU primarily focuses on foot-and-mouth disease, it could be adapted by agreement of the parties for handling other major animal disease emergencies such as BSE. The
MOU sets out a national coordination framework to ensure close integration of responsibilities and actions within and across jurisdictions which builds on existing animal disease and emergency management plans. The MOU is at the Council of Australian Governments (COAG) website.
The Emergency Animal Disease Response Agreement is a landmark agreement that has been ratified by Australia's governments and livestock industries, with the aim of ensuring a rapid and efficient response to exotic animal disease incursions in Australia's livestock sector. The agreement is a world first and includes mechanisms for formal government/industry consultation on resource allocation, funding, training and risk mitigation. Details of the agreement are at the
Animal Health Australia website.
The Australian livestock industries and governments have taken a proactive approach to being prepared for a BSE case. The AUSVETPLAN Disease Strategy for BSE provides a technical response plan that describes the animal health response a BSE case in Australia. The document was first produced in 1996 and has been updated since. It sets out guidance on control and eradication of BSE and is based on sound analysis and linking policy, strategies, implementation, coordination and emergency-management plans.
AUSVETPLAN is available from the Animal Health Australia website.
These plans are regularly tested through
simulation exercises and reviewed in light of new scientific information.
