Raw dog food: spread of antibiotic-resistant bacteria

Antibiotic-resistant bacteria: superbugs

Antibiotic-resistant "superbugs" is one of the greatest threats to public health according to The World Health Organization (WHO).

They usually conjure up images of hospital environments.

The research may point to a less obvious source, which is the family dog.

Just after discovering antibiotic-resistant bacteria in different types of raw dog food, many researchers have warned of "an international public health risk".

Researchers stated in a press release about their study that "The trend of feeding dogs raw food could accelerate the spread of antibiotic-resistant bacteria".

That is will be presented at the ECCMID (European Congress of Clinical Microbiology and Infectious Diseases).

Raw dog food: spread of antibiotic-resistant bacteria

Raw dog food: Antibiotic-resistant increase

It was reported that Antibiotic-resistant bugs can make common infections potentially fatal and minor injuries.

There has been a significant increase in resistance in recent years due to the overuse of these drugs in humans and farm animals.

 

In this sense, a team from the University of Porto analyzed 55 dog food samples from 25 brands.

In this dog food study, they investigated 14 types of frozen raw food - to detect the presence of enterococcus bacteria.

The bacteria can live safely in the human and animal intestines.

Whereas, it can be dangerous in other parts of the body and can be resistant to antibiotics.

According to researchers statements, all samples of the raw dog food contained antibiotic-resistant enterococci.

Namely, it contained bacteria resistant to linezolid, which is an antibiotic of last resort.


Spread of antibiotic-resistant bacteria

Genetic sequencing revealed that some of these bacteria in the raw dog food were of the same type as those found in hospital patients.

Practically, with those found in the UK, Germany, and the Netherlands.

According to the statement by researcher Ana Freitas, there is an international public health risk mainly related to the human's close contact with dogs.

She also added that the European authorities must make people aware of the potential health risks when feeding raw pet food.

Or when manufacturing dog food, including hygiene practices, the selection of ingredients must be reviewed.

In addition to that, dog owners must wash their hands after handling pet food and disposing of dog excrement.


Bacteria transmitting between dogs and owners

In another study carried out by a Portuguese team tested pet owners and animals from about 80 households for bacteria carrying the MCR-1 gene.

That offers resistance to the antibiotic of last resort colistin.

In the level of a separate research, they say that resistance to a last-resort antibiotic can be transmitted between pet dogs and their owners.

According to the study results, 126 humans were healthy, while half of the 102 pets sampled had urinary tract or skin infections.

Four humans and eight dogs tested positive for MCR-1 carrier bacteria, and in two outbreaks the gene was found in both the dog and its owner.

Bacteria transmitting between dogs and owners

Finally, she reported that genetic analysis of the various samples studied suggested that.:

In one of the two cases, the gene had been passed between the animal and the owner.

Furthermore, the gene was thought to have passed directly from dogs to humans.

This has raised concerns that pets could spread resistance to last-resort antibiotics.

Antibiotic resistance is one of the greatest public health threats facing humanity, according to word human organization (WHO).

Drug-resistant infections kill around 700,000 people a year worldwide.

The UN has warned that this could rise to 10 million by 2050 if no action is taken.
