The Study: How Raw Meat Affects Dogs’ Gut Bacteria
The research team at the University of Bristol analyzed the intestinal bacteria of 600 healthy pet dogs, investigating whether they carried E. coli that could resist ciprofloxacin, a widely used antibiotic in both human and veterinary medicine.
The findings, published in One Health, revealed a strong link between feeding dogs raw meat and the presence of antibiotic-resistant bacteria in their digestive tracts.

The study involved dog owners completing surveys about their pet’s diet, environment, and antibiotic history. Statistical analysis showed that raw feeding was the only significant factor associated with excreting ciprofloxacin-resistant E. coli—a clear indication that the diet played a crucial role in fostering antibiotic resistance.
Does Raw Dog Food Promote Growth of Antibiotic-Resistant Bacteria?
While E. coli is a naturally occurring bacterium in the intestines of humans and animals, certain strains can cause severe food poisoning, urinary tract infections (UTIs), and even life-threatening bloodstream infections.
Ciprofloxacin, classified by the World Health Organization (WHO) as a critically important antibiotic, is a key treatment for these infections. However, the growing resistance to this drug means that infections become harder to treat, leading to longer hospital stays, increased medical costs, and higher mortality rates.
A Growing Concern for Public Health
The implications of this study extend beyond just pets. When dogs excrete resistant bacteria into their environment, they increase the chances of transmission to humans through:
✔ Close contact, such as petting and licking
✔ Contaminated surfaces in the home
✔ Handling raw meat when preparing pet food
Once humans ingest these resistant bacteria, they can settle in the gut without causing immediate symptoms, potentially leading to infections years later. Given that the UK sees hundreds of thousands of UTIs caused by E. coli every year, and thousands of bloodstream infections leading to deadly sepsis, the role of antibiotic resistance in worsening these conditions cannot be ignored.

Raw Meat: A Breeding Ground for Resistant Bacteria
Professor Matthew Avison, a lead researcher in the study, explains that raw meat is frequently contaminated with antibiotic-resistant bacteria. Cooking meat effectively kills these pathogens, but when served raw—whether intended for human consumption or sold as raw pet food—it introduces a direct risk to both pets and their owners.
“Choosing to feed a dog raw meat means a person almost certainly has to handle the raw meat,” says Professor Avison. “Our research is clear that raw feeding also means pet owners are likely to be interacting with a pet that is excreting resistant E. coli.”
A Safer Approach: How Pet Owners Can Reduce Risk
While the study does not outright condemn raw feeding, it highlights the need for caution. Pet owners concerned about antibiotic resistance should consider the following steps:
1. Switch to Cooked or Commercially Prepared Diets
The simplest way to reduce risk is by feeding pets cooked meat or high-quality commercial dog food, which undergoes stringent safety checks. Cooking meat to the appropriate temperature eliminates harmful bacteria, making it safer for both pets and owners.
2. Choose Antibiotic-Responsible Meat Sources
If pet owners prefer a raw diet, they should source meat from farms with strict antibiotic usage policies. Countries like the UK have significantly reduced antibiotic use in farming, making their meat products a safer option compared to imports from regions with higher antibiotic resistance rates.
3. Maintain Strict Hygiene Practices
When handling raw meat, it is crucial to follow proper hygiene protocols:
✔ Wash hands thoroughly after handling raw food
✔ Clean and disinfect food bowls and preparation surfaces
✔ Avoid letting pets lick faces or hands immediately after eating raw meat
✔ Store raw meat safely in separate containers to prevent cross-contamination
Regulatory Action: What Needs to Change?
As antibiotic resistance continues to rise, experts are calling for stricter regulations on raw pet food production. Professor Avison suggests that:
✔ Companies producing raw dog food should be required to source meat from farms with responsible antibiotic policies
✔ Stricter limits should be set on bacterial contamination levels in raw pet food
✔ Regular testing for resistant bacteria should be mandated before raw food reaches the market
These measures could help reduce the spread of resistant bacteria, protecting both pets and humans from future health crises.
The Bigger Picture: Antibiotic Resistance in a Global Context
The fight against antibiotic resistance extends far beyond pet food. While human healthcare has made strides in reducing unnecessary antibiotic use, agriculture and pet food industries remain critical battlegrounds.
The nearly complete cessation of fluoroquinolone use in UK farm animals has contributed to declining resistance rates, yet high usage in other parts of the world continues to drive bacterial evolution.
The World Health Organization (WHO) has repeatedly warned about the growing global threat of antibiotic resistance, estimating that by 2050, drug-resistant infections could surpass cancer as a leading cause of death worldwide.
Addressing resistance in every sector, including pet nutrition, is crucial to preventing a post-antibiotic era where common infections become untreatable. The best collar size for an American Staffordshire Terrier ensures a comfortable and secure fit for your dog during walks and training.
The Growing Threat of Antibiotic Resistance and How Pet Owners Can Respond
The rise of antibiotic-resistant bacteria is a pressing global concern, and the role that pet ownership plays in this crisis is often overlooked. While much of the focus has been on human antibiotic overuse, research increasingly shows that the way we care for our pets—particularly their diet—can contribute to the spread of drug-resistant infections.
The findings from the University of Bristol study serve as a wake-up call, highlighting how feeding raw meat to dogs is linked to the excretion of E. coli that cannot be killed by ciprofloxacin, a critical antibiotic used in both human and veterinary medicine.
This issue extends beyond pet health. When dogs shed antibiotic-resistant bacteria in their feces, these microbes can persist in homes, public parks, and other environments where people and animals interact. The bacteria can be transferred through direct contact with contaminated surfaces, petting, or even through particles in the air.
Once introduced into the human body, these bacteria can remain in the intestines for years, posing a significant risk if an individual develops an infection that is difficult to treat due to antibiotic resistance.
Responsible Pet Ownership and Reducing Risk
Pet owners play a crucial role in minimizing the risk of antibiotic-resistant bacteria spreading from their dogs to their households and beyond. One of the most effective ways to do this is by reconsidering raw food diets.
Cooking meat thoroughly kills harmful bacteria, making it a safer option for pets. If pet owners still prefer a raw diet, they should ensure that the meat is sourced from farms with strict antibiotic policies and tested for resistant bacteria before being sold.
In addition to dietary changes, practicing good hygiene is essential. Washing hands after handling pet food, cleaning up dog waste promptly, and disinfecting areas where pets eat and sleep can help reduce bacterial transmission.
Regular vet check-ups and responsible antibiotic use for pets are also critical. Overprescription or improper use of antibiotics in veterinary care can contribute to the rise of resistant bacteria.
Pet owners should follow their veterinarian’s advice carefully and avoid seeking unnecessary antibiotic treatments for minor ailments. To find out the what size collar for an Affenpinscher, ensure you measure your dog’s neck correctly for a perfect fit.
Final Thoughts: Is Raw Feeding Worth the Risk?
While raw feeding proponents argue for its benefits, the scientific evidence highlighting its risks is hard to ignore. The University of Bristol’s study is yet another reminder that pet diets do not exist in isolation—what we feed our pets can have direct consequences for human health. Hope so, now you know Does Raw Dog Food Promote Growth of Antibiotic-Resistant Bacteria.
As the debate continues, one thing remains clear: responsible pet ownership includes making informed decisions about diet and hygiene. Whether choosing a raw, cooked, or commercial diet, safety should always come first—for the well-being of pets, owners, and the wider community.
