Raw diets (BARF, prey model, etc.) have grown in popularity, but peer-reviewed evidence on benefits is limited. Risks—bacterial contamination, nutritional imbalance, zoonotic disease—are well-documented. Use the Nutritionist Specialist and Nutrition Label Scanner for evidence-based guidance.
Proponents cite shinier coats, smaller stools, and perceived "natural" alignment. Controlled studies on long-term health outcomes are scarce. AAFCO feeding trials demonstrate commercial diets support growth and maintenance.
Multiple studies find raw diets contaminated with Salmonella, E. coli, Listeria. Pets can shed these pathogens, posing risk to humans, especially immunocompromised individuals. Nutritional analysis of commercial raw diets often reveals deficiencies (calcium, phosphorus, vitamin D) or excesses.
Warning: Raw diets pose zoonotic risk. Handle raw meat with care; avoid feeding in households with young children, elderly, or immunocompromised individuals. FDA and AVMA advise against raw meat diets for these reasons.
High-quality commercial diets (AAFCO-approved, WSAVA guidelines) provide complete nutrition. For owners seeking "natural" options: limited-ingredient, novel protein, or fresh-cooked (properly formulated) diets may address preferences while reducing risk.
If raw feeding is chosen despite risks: use commercially prepared raw that has undergone high-pressure pasteurization (HPP) to reduce pathogens. Ensure formulation meets AAFCO standards. Consult a board-certified nutritionist.
Home-cooked diets require formulation by a veterinary nutritionist. Improper formulation commonly causes deficiencies (taurine, calcium, trace minerals) leading to serious disease.
- Raw diets: limited evidence of benefit; documented pathogen and nutritional risks.
- Zoonotic risk (Salmonella, etc.)—concern in vulnerable households.
- Many raw diets nutritionally imbalanced.
- Commercial AAFCO diets are evidence-based; consider HPP raw if raw chosen.
- Home-cooked requires veterinary nutritionist formulation.
