The yellow discolouration is to be solely considered a quality defect. Operators of hog slaughter and processing establishments are responsible for ensuring that discoloured products, including yellow bones, are not offered for sale to consumers. No action or special inspection activity is to be undertaken by CFIA during post-mortem procedures as this is an operator quality managed defect. Furthermore, considering that the yellow colouring of bones may disappear after the carcass has remained a certain time in the cooler, operators can decide that the removal of parts of bones that showed a yellow discoloration at the time the carcass was dressed, is no longer justified once the carcass is ready to be boned at the establishment or shipped. Should the removal of these bones from the carcass take place at another Federally Registered Establishment a control program acceptable to the Veterinarian in Charge shall be put in place.
There are four different levels of grading, from Listed at the bottom to Grade I at the top. The latter are higher-class races for bigger prizes for horses of the same age group (2, 3 or 3 and up) and may further be restricted by gender. The weight conditions of the races may vary provided they meet the Committee's standards to ensure competitiveness. Many grade I races are " weight-for-age ", with weights adjusted only according to age and gender, and also there are 'set weights' where all horses carry the same weight (usually applicable when all horses are of the same age and gender). Furthermore, there are "conditions" races, in which horses carry weights that are set by conditions, such as having won a certain number of races, or races of a certain value. Finally, some graded stakes are " handicaps ", in which an official handicapper assigns weights to each horse in an attempt to equalize the competition.
