The inspector's sole task is to protec t the human food supply. Cancer eye is a common cause of condemnation in western herds. It is a good example to consider localization or systemic spread. Th e carcass of market cows with early cancer eye tumors localized to the eye region can be pass for human food once the head is removed and condemned. Malignant lymphoma, which is caused by Bovine Leukemia Virus, is an other common cause of condemnation.
Malignant lymphoma affects primarily the lymph nodes.
The livestock owner should know that cows with these Malignant Lymphoma lesions would be condemned at slaughter. Commo n locations are the abomasum and uterus. Cows with abomasal involvement may show a variety of clinical signs related to the GI tract. The veterinarian sometimes finds uterine lesions during routine reproductive examination. During the examination of the internal organs by the meat inspector, these unseen lymph node lesions will be discovered.
