Aronia melanocarpa, a main constituent of black chokeberry, provides a rich source of bioactive molecules including polyphenols, flavonoids, and anthocyanins and has been used for long in traditional medicine due to its various health-promoting and disease-alleviating properties. The aim of our literature survey was to provide an actual update of evidence regarding the antibacterial activities exerted by Aronia melanocarpa and its potential application for the treatment of human bacterial pathogenic including food-borne infections. Our survey revealed that distinct ingredients in Aronia melanocarpa do not only inhibit growth of Gram-positive and to a lesser extent of Gram-negative bacteria, but also biofilm formation that is even more pronounced upon combined application. Furthermore, the anti-microbial effects against food-spoiling bacteria underscores the application of defined Aronia-derived molecules in food preservation decreasing the risk for transmission of foodborne pathogens and thereby, improving food safety. Notably, in vivo studies revealed that prophylactic Aronia juice application alleviated murine Listeria monocytogenes-induced enteritis, dampened growth of streptococci involved in dental caries development, and decreased the incidence of urinary tract infections in nursing home residents. In conclusion, Aronia-derived bioactive molecules exhibit promising anti-bacterial and disease-alleviating effects that should be further elucidated in clinical studies.  Kulcsszavak: Aronia melanocarpa, black chokeberry, anti-bacterial effects, immune-modulatory effects, novel anti-microbial therapies, food-borne pathogenic infections, food packaging, multidrug-resistant (MDR) bacteria, anti-biofilm forming effects
