New findings on raw cat foods
Commercial raw cat foods that are sold shelf-stable or kept at room temperature may pose a notable health risk to both cats and the people who care for them. An analysis published in Communications Biology identified disease-causing microbes in raw or partially cooked meat products meant for cats, including items stored frozen, refrigerated, or as freeze-dried formats bought online or in stores. The study highlights that these products often lack warning labels about the potential for live bacteria, viruses, or parasites, which could make a family sick.
Pathogens detected and their implications
The researchers detected several harmful microbes in the tested products, such as Salmonella, Cronobacter, and Escherichia coli (E. coli). In addition, they found antibiotic-resistant strains, including Pseudomonas, Klebsiella, and Clostridium perfringens. Pseudomonas can cause severe infections in the lungs, blood, and urinary tract; Klebsiella is associated with fever, chills, and potentially pneumonia and urinary issues; Clostridium perfringens is linked to gastroenteritis and food poisoning occurrences around holidays like Thanksgiving.
The presence of these pathogens is particularly concerning because they can transfer from pets to humans. Vulnerable groups—young children, the elderly, pregnant individuals, and those with compromised immune systems—face higher risks from exposure to these bacteria and any associated toxins. The study’s authors stress that secrecy around how thoroughly meat ingredients are cooked may leave families unaware of the true risk.
What this means for pet owners
While raw pet foods have gained popularity for claims about nutrition and palatability, the new findings suggest a need for heightened caution. The study notes that the risk is not limited to raw diets for cats; antibiotic-resistant bacteria have already been documented in raw dog foods as well. Owners should consider the potential for cross-contamination in the home—kitchen surfaces, utensils, and feeding areas can become contaminated, increasing the chance of exposure for humans and other pets alike.
Regulatory and policy context
Currently, U.S. Food and Drug Administration (FDA) testing on raw cat foods covers a limited range of bacteria. The researchers argue that their broader identification of pathogens could inform future regulatory policies and testing standards, improving safety labeling and manufacturing controls across the industry. They point out that some human cases in federal databases share genetic similarities with the products studied, implying that people may have become ill from the same sources examined in the research.
Practical steps for safer pet care
Pet owners interested in raw diets should discuss options with a veterinarian, weigh the risks, and implement strict kitchen hygiene. If raw or freeze-dried products are in use, consider thorough handwashing after handling, dedicated feeding areas, and regular cleaning of surfaces and tools. Evaluate alternative diets with proven safety profiles if family members include young children, pregnant individuals, or immunocompromised people. Staying informed about evolving regulatory standards can also help owners make safer choices for both companions and households.
