In my work as a veterinary educator, I have observed a large gap in the medical knowledge of anatomy and pathology of the lymphatic system of food animals. The goal of this book is to enhance the understanding of the lymphoreticular tissues' anatomy and pathology in food animals.
This 102 page work is a collection of 115 factual gross anatomical and pathological illustrations of carcass lymph nodes and spleens in different species of food animals as seen in abattoir settings.
The position, drainage area and destination of the lymph vessels are also described.
Some lymph node lesions are supported with histological and microbiological findings. The final disposition of carcasses is described in some cases.
Veterinarians and inspectors working in meat inspection will be able to better understand the unique structure and relationship between lymph node and spleen in different animal species. Consequently, they will be able to perform more accurate postmortem dispositions on food animal organs and carcasses. Students of veterinary medicine will benefit by using this book as an essential educational material for their course requirements on the anatomy and pathology of lymphoreticular tissue in food animals.
The majority of gross anatomical illustrations in this work were selected from beef animals between 1.5 and 2.5 years of age that were slaughtered in Ontario abattoirs. Other ruminants include calves, cows, lambs, and sheep. Equine species are also presented.

The purpose of this book, "Colour Atlas of Sheep and Goat Pathology and Meat Inspection", is to facilitate the interpretation of sheep and goat pathology and the final disposition of the carcasses at the abattoir level, thereby benefiting all personnel engaged in sheep and goat production and inspection.
This 128 page work is a collection of 241 factual clinical and pathological illustrations of sheep and goat conditions and diseases found during meat inspection procedures in the abattoir. Material presented in this work was collected for teaching purposes as a part of a broader study of sheep and goat pathology in Canada.
Veterinarians and inspectors working in meat inspection will benefit from this work, as decisions have to be made quickly based solely on visual appraisal, usually without the clinical history of the animal. All clinical and gross anatomical illustrations were selected from sheep and goats that were slaughtered in Ontario abattoirs.

This work contains information needed for diagnosing pathological conditions and the disposition of carcasses for human consumption. The atlas is presented in 15 chapters and contains 904 colour illustrations of cattle diseases and conditions. Eleven chapters are described according to the body system and the other four include parasitic diseases, diseases specific to cattle, neoplasms, and meat hazards. Descriptive text is included for all significant conditions and diseases.
Complete postmortem findings, and in some cases histological and bacteriological findings with dispositions are challenges for veterinarians and inspectors engaged in cattle inspection. This book describes factual dispositions of significant cases done by the author who has performed thousands of antemortem and postmortem examinations of animals and animal carcasses. In any classic HACCP program, the first control point (CCP) for all food is “the safety of the raw product received”. In the case of raw meat, this first CCP is the acceptable condition of the animal, and the animal carcass. The only intervention is antemortem and postmortem inspection performed by a qualified and well trained veterinary inspector or qualified meat inspector.

This book, “Colour Atlas of Poultry Pathology and Meat Inspection”, is a collection of illustrations of pathology found at the time of antemortem and postmortem examinations of poultry. In total there are 524 illustrations in 15 chapters. 11 chapters are grouped in systems according to the most significant lesions found in these systems. The last four chapters include poultry neoplasms, hazards of meat, diseases of ratites, rabbit pathology and meat inspection.
This work offers a North American perspective of poultry diseases and conditions found in abattoirs.
The majority of illustrations of poultry pathology in this book have been selected from 6-8 week old broiler chickens slaughtered in Ontario abattoirs. Other species of poultry include fowl, turkey, ducks and geese. In some cases post mortem lesions are supported by histological and bacteriological examinations.
This book will provide all personnel engaged in meat inspection, including veterinarians and inspectors of both the provincial and federal governments in Canada, with ongoing reference of poultry and rabbit pathology and diseases. In most cases, two colour illustrations appear on one page in order to better project a visual image of the displayed lesions for inspectional staff. With this way of presentation, inspectional staff will be able to better associate the displayed color text lesions with actual lesions on the postmortem examination. More emphasis has been placed on the disposition of bird carcasses. This work will assist the inspectional staff to better diagnose pathological lesions of poultry, and consequently to perform more accurate postmortem dispositions of bird carcasses and viscera.
Veterinarians in large animal and poultry practices and students of veterinary and agricultural colleges will benefit from the use of this high-quality educational and reference tool for daily work activity and course requirements.

This "Color Atlas of Fetal Development and Reproductive Organs Pathology in Food Animals" offers an abattoir perspective of reproductive pathology in food animals. The Atlas is presented in 6 chapters and contains 254 color illustrations of reproductive organ pathology and udder diseases in food animals. The first chapter deals with fetal development and the second with inflammation of udders in food animals. The other four chapters are grouped according to the species of animals. The Atlas also describes factual dispositions of carcasses done by the author who has performed a large number of antemortem and postmortem examinations of food animals with reproductive system pathology. In some cases, histological and bacteriological findings are also recorded.
Complete postmortem findings of carcasses with reproductive organ lesions are challenges for veterinarians and inspectors engaged in meat inspection as well as for veterinary practitioners specializing in reproductive pathology of food animals. This atlas will help the reader to understand the criteria used by the author for condemnation of animals affected with reproductive pathology. The information about general pathological conditions with antemortem and postmortem findings and disposition are also included at the beginning of this book. The clinical and gross anatomical illustrations in the Atlas were selected from the following animals: cattle (calves, heifers, steers, cows, bulls), sheep, goats, pigs and horses. All animals were slaughtered in Ontario abattoirs.
The author wishes to acknowledge and thank Dr. Robert Foster, Professor at Department of Pathobiology, University of Guelph, Ontario, Canada for his proofreading and valuable comments for certain conditions mentioned in this book.
