The focus of the CFIA is food safety. When there is a question as to a food or a process being safe or unsafe, the decision is always to make a mistake on the side of safety. In the slaughter plants, this means that if there is a question, the part is either sent as animal food or condemned. There was a directive (or change in procedure) issued in December of 2004 that has changed marking and identifying procedures in slaughter plants. This directive details the responsibilities of the plant personnel and the CFIA personnel. There are now 3 categories of defects: Operator Managed Conditions (such as contamination or over-scalding), CFIA/Operator Managed Conditions, and CFIA Managed Condition. Four items that cause the greatest loss to producers include abscesses (most significant reason for loss), arthritis (about 14% of all carcasses being condemned and about 50% of trim weight), adhesions (about 6 or 7% of the trims), and the deduction for boars and ridglings. Lower trims can be realized by preventing or reducing injuries, preventing or reducing systemic infections, preventing or reducing respiratory problems, and marking all piglets that have not had 2 testicles removed and removing them later.
