Description of flow chart for actions to follow if there is suspicion of foreign animal disease at an abattoir (ante-mortem)
This diagram lists the sequence of events to follow if a Foreign Animal Disease is suspected in an abattoir during ante-mortem examination. The suspect animal lot will be segregated and the farm of origin of the suspect lot will be identified. In order to follow-up on and support the risk determination associated within the abattoir, the contact information for the farm of origin must be forwarded quickly to the Local District veterinarian, via the Part A 1.2 of the Premises Investigation Questionnaire.
After segregation and farm identification, it is suggested that the inspection manager/regional veterinary officer/foreign animal specialist/district veterinarian as well as the plant management may be informed of the Foreign Animal Disease suspicion at this time or delayed until the clinical exam of the animals is done.
The Canadian Food Inspection Agency veterinarian will perform the clinical examination of the suspect animals of the same origin which will include clinical signs in live animals as well as observing lesions while performing necropsy, if needed, as there will be instances when complete necropsy will not be done at this time (for example, vesicular diseases). The number of affected animals within the group must also be determined.
With the above information collected, the Veterinarian in Charge shall contact and consult the Foreign Animal Disease Specialist and Inspection Manager. They will help the Veterinarian in Charge with the risk determination. The situation will be deemed to be high risk or low risk (confirmatory negative).
The Veterinarian in Charge will immediately inform the abattoir management of the extent of risk determined and on that basis the establishment will activate their appropriate emergency plan. The Veterinarian in Charge will also communicate the level of risk determined to District Veterinarian and Regional Veterinary Officer and as the Foreign Animal Disease specialist and Inspection Manager have already been involved in risk determination, there is no need to notify them again.
If the situation is deemed high risk (Section 188.8.131.52), there will be declaration of plant as infected premises using the Canadian Food Inspection Agency form 4204 and so movement restriction of animals into plant will be put into effect (section 184.108.40.206). Some other actions taken will be the trace back of farm of origin and trucks which were used to transport the suspect animals to slaughter house and the route taken by them (section 220.127.116.11), appropriate sample collection with proper packaging, submission into the Laboratory Sample Tracking System and shipping the samples with prior proper notification (section 18.104.22.168) segregation of the carcasses, products and by-products on site (section 22.214.171.124) and cleaning and disinfection activities (sections 126.96.36.199 and 188.8.131.52)
If the situation is deemed low-risk (section 184.108.40.206) then movement restriction is not applicable, trace back of the farm of origin is done (section 220.127.116.11), samples are to be sent to the appropriate laboratory as "Confirmatory Negative" (section 18.104.22.168), segregation of carcasses, products and by-products by an approved method is done (section 22.214.171.124) and proceed with cleaning and disinfection activities (sections 126.96.36.199 and 188.8.131.52)
