Through this message disseminated on social media, she is raising families’ awareness about the proliferation of dangerous bacteria in the kitchen and the risks to vulnerable individuals.

Nearly 7 out of 10 French people see their pet as a full-fledged member of the family, according to a 2023 Ipsos poll. Hence it’s not uncommon for dogs to be involved in daily routines, including meal times. But this affection, sometimes translated into the habit of letting them lick the leftovers on the plate, is far from harmless.

Persistent microbes, even after washing

Océane Sorel, a virology researcher better known on social media under the handle @thefrenchvirologist, warns that dogs’ tongues carry pathogenic bacteria. According to her, when dogs lick a plate, these microbes end up on the dishes, then in the sink, on sponges, and sometimes on countertops, thus exposing the house’s occupants to cross-contamination.

Contrary to popular belief, neither manual washing nor the dishwasher, especially on eco mode, always suffice to eradicate these pathogens. “The temperature is too low to kill all the bacteria,” explains the specialist.

Increased danger for the most vulnerable

The situation becomes even more concerning when sharing dishes with vulnerable individuals, such as pregnant women, young children, the elderly, or immunocompromised individuals. For these people, infections can be much more severe.

Océane Sorel thus recommends placing the plates directly in the dishwasher without offering them to your dog. If you want to treat your four-legged friend, it’s preferable to give them a portion of the leftovers provided they are suitable for their diet in a clean bowl dedicated to them.
