BSE, A 90s Chronology of Events

And here’s another interesting chunk of Archivery via Period Sites in Period Browsers that doesn’t appear to be online anywhere else – A mid 1990s chronology of the BSE outbreak in the UK as published by the MAFF.

Timeline

DATEEVENT
November 1986Disease identified by Central Veterinary Laboratory following study of affected cow referred to Weybridge for investigation and post mortem. Transmission experiments needed which required fresh material from animals thought to be suffering from the same problem
April 1987Initial epidemiological studies started. Objective was to obtain detailed data from a case study of 200 herds
5 June 1987CVO informs Ministers about new disease. Transmission experiment then put under way. Not known if disease was transmissible at that stage. Normal time for disease to develop in mice proved to be about 10 months. Results available September 1988 and published October 1988 in Veterinary Record
15 December 1987Initial epidemiology studies completed. Concluded ruminant derived meat and bone meal was only viable hypothesis for cause of BSE
January-March 1988Double checking of feeding histories of affected animals initiated; request sent to compounders for details of inclusion of meat and bone meal in rations fed
April-May 1988Responses from compounders further substantiated hypothesis for cause of BSE

29 March 1996The Beef (Emergency Control) Order 1996 (SI 1996 No 961) prohibits the sale for human consumption of any meat from bovine animals showing more than two permanent incisors. The prohibition was introduced as an emergency measure pending consideration of a more targetted approach to protecting human health
29 March 1996The Bovine Spongiform Encephalopathy (Amendment) Order 1996 (SI 1996 No 962) prohibits the sale or supply of any mammalian meat and bone meal, or any feeding stuff known to include mammalian meat and bone meal, for the purpose of feeding to farm animals, including horses and farmed fish. This requirement was introduced on the advice of the independent Spongiform Encephalopathy Advisory Committee
29 March 1996The Specified Bovine Material Order 1996 (SI 1996 No 963) replaces the Specified Bovine Offal Order 1995 and introduced a requirement that the whole head of all cattle over 6 months, except for the tongue provided that it can be removed without contamination, must be treated in the same way as material designated as ‘specified bovine offal’. This requirement was introduced on the advice of the Spongiform Encephalopathy Advisory Committee
3 April 1996Government announces changes to the Beef (Emergency Control) Order and the introduction of a 30 month slaughter scheme to ensure that all bovine animals over the age of 30 months at the time of slaughter do not enter the human food or animal feed chain.

1 May 1996The Specified Bovine Materials (No 2) Order 1996 (SI 1996 No 1192) amends and replaces the Specified Bovine Material Order 1996. Its effect is to amend the way in which existing controls apply to specified material from animals slaughtered under Commission Regulation 716/96. It requires specified bovine material (SBM) to be removed from carcases and handled separately, just as for animals below 30 months. The carcase meat from cattle slaughtered under the Commission Regulation must be dyed a different colour from SBM. The Order also brings the existing rules on rendering and disposal into line with EC requirements
1 May 1996The Bovine Animals (Enforcement of Community Purchase Scheme) Regulations 1996 (SI 1996 No 1193) make provision for the enforcement of certain of the new requirements of Commission Regulation 716/96.

It applies to approved operators of incinerators or rendering plants, approved under the Specified Bovine Material (No 2) Order 1996 and to licensed operators of slaughterhouses licensed under the Fresh Meat (Hygiene and Inspection) Regulations 1995, whose premises are designated under the terms of Commission Regulation 716/96

24 July 1996Following SEAC advice the Government announces its intention to introduce controls to require the removal of sheep’s heads from the food chain, an interim measure pending EU wide controls. This followed publication of evidence that BSE could be isolated from the spleen of sheep experimentally infected with BSE
