Healthcare‐associated infections (HAIs) are a global concern, affecting all western hospitals, and profoundly impairing the clinical outcome of up to 15% of all hospitalized patients.

Persistent microbial contamination of hospital surfaces has been suggested to contribute to HAIs onset, representing a reservoir for hospital pathogens. On the other hand, conventional chemicals‐based sanitation do not prevent recontamination and can select drug‐resistant strains, resulting in over 50% of surfaces persistently contaminated.

There is therefore an urgent need for alternative sustainable and effective ways to control pathogens contamination and transmission.

Toward this goal, we recently reported that a probiotic‐based sanitation can stably decrease surface pathogens up to 90% more than conventional disinfectants, without selecting resistant species.

This paper summarizes some of our most significant results.
