Slide 2

BSE: Background First portrayed in UK in 1986 (>180,000 cases in UK steers to date) BSE present in many nations of Western Europe Peak of the scourge in UK 1992-1993 Surveillance in Canada started in 1992 BSE identified in Alberta in 1993 ( in one creature imported from UK ) BSE as of late found in Japan, Israel, Slovakia, Czech Rep, and Poland

Slide 3

Basic suppositions BSE first emerged in UK and was engendered through the reusing of contaminated ox-like tissues into ruminant food (meat-and-bone dinner). The fare of contaminated creatures and tainted food from the UK spread the BSE specialists to different nations were it was reused and engendered by means of the creature natural way of life.

Slide 4

1997: Ruminant Feed Bans in North America Canada executed a decide that restricts the encouraging of most mammalian proteins to ruminant creatures (“feed ban”). US executed a comparable guideline that year.

Slide 5

Variant Creutzfeldt-Jakob Disease (vCJD) vCJD is a neurological illness in people ascribed to utilization of meat items from BSE-influenced creatures. Most vCJD cases have been in UK (135). vCJD was found in 5 different nations: Canada * (1) , France # (6) , Ireland* (1) , Italy # (1) , USA * (1) * Patients in Ireland, US , and Canada had invested augmented energy in UK . # Some patients in France and the Italian patient had not went to UK . France imported critical measures of hamburger from UK.

BSE in Canada 2003 Jan 31 A more established reproducer dairy animals (6-8 yr) in Alberta was denounced with analysis of conceivable pneumonia and butchered (BSE not suspected). Head was gathered and put away, corpse sent to “inedible” rendering for pet sustenance, modern utilization. Cerebrum was not inspected instantly because of overabundance. Might 16 BSE analyzed in Alberta commonplace lab by immunohistochemistry (PrP Sc in medulla). Might 18 BSE affirmed in Winnipeg. Might 20 BSE affirmed in UK as “typical” BSE. Canada declared case; USDA import forbiddance.

Slide 7

Rendering Canadian powers guaranteed that the remains had not entered human sustenance chain—inedible rendering just. Rendered item went to : 8 food plants . All homesteads accepting food ( not expected for ruminants) reached to figure out whether any ruminants on premises. Provided that this is true, they were further researched. 2 ranches . Eliminated, couldn\'t discount unintentional nourishing of poultry food to steers on same premises. Pet sustenance producer (Alberta). Pooch sustenance was transported to one firm in US. There is no proof that pooches get any TSE. US firm requested that clients return nourishment to wholesalers for legitimate transfer.

Slide 8

Canadian Response Plan ( lines of request) Feed : Over 200 homesteads have been examined, found in consistence with obliged nourishing practices. Case crowd : No data accessible about utilization of MBM on last ranch where BSE cow lived; the homestead was eradicated and creatures tried. Follow back : Search for the conceivable origin of BSE influenced bovine (presumably Saskatchewan, potentially Alberta) was finished. Crowds where BSE cow mixed together( (conceivably presented to same food) were researched. Follow forward : Herds where posterity from case group may have lived were researched.

Slide 9

US Follow-up US government organizations (FDA CVM [Center for Veterinary Medicine], FDA ORA [Office of Regulatory Affairs], USDA APHIS [Animal & Plant Health Inspection Services], USDA FSIS [Food Safety Inspection Service]) are catching up 5 bulls imported into the US from one conceivable crowd of starting point of BSE cow.

Slide 10

Results Approximately 2700 cows brains have been broke down by quick test (PrP Sc ELISA) and immunohistochemistry. All creatures tried negative (aside from the single positive file dairy animals). Give or take 25 ranches have been explored (Alberta, Saskatchewan, British Columbia). June 9: Canadian Food Inspection Agency (CFIA) reported that dynamic examination of the case is finishing. Extra testing and data social affair will proceed. A global survey group (OIE) in Canada is assessing the circumstance. A late hazard appraisal (Dec 2002) had demonstrated that the probability of BSE influencing steers in Canada was low. Current commonness of BSE in Canada must be exceptionally low—risk likely lower than before 1997.

Slide 11

BSE – Canada Further Information BSE in Canada will be a theme of dialog at the following meeting on July 17-18, 2003 of the FDA Transmissible Spongiform Encephalopathies Advisory Committee The Canadian Food Inspection Agency (CFIA) keeps up a site at http://www.inspection.gc.ca
