Abattoir condemnation data are a rich source of information for syndromic surveillance, and have the potential to provide early warning of emerging animal and zoonotic disease but have been under-utilized in the past.
It is unclear whether organ/body system data may be better suited for syndromic surveillance, as these data may provide more specific information on health outcomes than whole carcass condemnation data.
Farm location information is not routinely recorded for provincial abattoir condemnation data.
Portion condemnation data may be particularly useful, as these data can provide more specific information on health outcomes than whole carcass condemnation data.
Overall, the results for both types of portion condemnation data demonstrate that as you increase the detail in the covariate adjustment information, the size of the cluster decreases.
Information from sales-yard [ 10] and veterinary reports [ 11], and condemnation data collected at abattoirs [ 12- 14] have recently been investigated for inclusion into animal health syndromic surveillance systems.
A prospective system that incorporates the purposeful, standardized collection of partial condemnation data pertaining to organs of interest for disease surveillance could be validated with other health information.
Because farm location is not routinely recorded with condemnation data, a subset of cattle, in which a sample was sent for laboratory testing, were used to obtain geo-location information for the abattoir and farm.
Physicians explored the underlying reasons for poor adherence and attempted to assist with behavioral advice or they tried to strengthen motivation for adherence through information, condemnation, or shaming of the patient.
