fed raw whole chicken, but the clinical consequence References
of differences in the feline intestinal microbiota is still unknown6.
Raw food diets naturally cover the pets nutrient needs and are safe
Comparing nutrient content in 95 bone and raw food rations for adult dogs with recommended allowances, 60% had one or more nutritional imbalance. These imbalances included low calcium and vitamin D content, low iodine, copper, zink and/or vitamin A content and some included excess calcium7. Further there are published case reports on malnutrition and growth disturbances in puppies fed BARF diets8 as well as development of nutritional thyrotoxicosis following consumption of all-meat commercial dog food containing remnants of thyroid tissue9.
Raw food feeding signi cantly increases the risk of
the pet harbouring zoonotic infectious agents such as Salmonella sp. and Campylobacter jejuni1,10. Often pets are asymptomatic carriers but there are reports on fatal salmonellosis in cats related to infected raw food and there are indications that human clinical salmonellosis and campylobacteriosis are sometimes linked to pets and feeding them contaminated food.
Conclusions
Raw food feeding is primarily marketed through claims that are still unproven. It is possible to feed a balanced diet to the pet based on raw food, but often diets based on homemade receipts are nutritionally unbalanced. Furthermore feeding raw meat increases the risk of pathogenic bacterial contamination and there are currently no evidence supporting the superiority of feeding the meat raw compared with cooking or frying it before serving.
