It's a specific allergen point as it relates to BRC Mrs.Mars
The guidance doesn't suggested it is considered an allergen, and one could assume that the heifers would be weaned from milking prior to slaughter (kind of like feed withdrawl for medication)
Here is a USDA beef slaughter model where it says;
"Potential hazards should be controlled through the SSOPs, and the application of a microbiological intervention(s) later in the process. Recommend that the establishment should develop a written SOP for the entire dehiding process to demonstrate the proper skinning procedure"

So i'm thinking it's not an allergen per say, but like Mrs Mars pointed out about poultry, slaughterhouses are required to have a process in place to deal with a carcass IF it becomes contaminated (we don't condemn poultry with spilled ingesta.....those carcasses are reconditioned)
