This study was designed to assess various environmental sources and commonly touched surfaces as potential carriers of ARB and ARGs with implications for public health. A total of 392\u2009samples, including sewage (36), sludge (36), diapers (20), plastics (20), water sachet polythene bags (20), food wastes (20), soil beneath dump sites (20), and frequently touched surfaces such as restroom floors (80), corridors (24), door handles (56), and room floors and walls (60), were collected and screened for the presence of resistant bacteria carrying genes such as\n bla<\/jats:italic>\n \n KPC<\/jats:italic>\n <\/jats:sub>\n ,\n bla<\/jats:italic>\n \n NDM-1<\/jats:italic>\n <\/jats:sub>\n ,\n bla<\/jats:italic>\n \n CMY-2<\/jats:italic>\n <\/jats:sub>\n ,\n bla<\/jats:italic>\n \n IMP<\/jats:italic>\n <\/jats:sub>\n ,\n bla<\/jats:italic>\n \n OXA66<\/jats:italic>\n <\/jats:sub>\n and\n MecA<\/jats:italic>\n . Additionally, we employed standard techniques to detect methicillin-resistant\n \n \n Staphylococcus aureus<\/jats:ext-link>\n <\/jats:named-content>\n <\/jats:italic>\n (MRSA) and extended-spectrum \u03b2-lactamase (ESBL)-producing\n Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa<\/jats:italic>\n and\n \n \n Acinetobacter baumannii<\/jats:ext-link>\n <\/jats:named-content>\n <\/jats:italic>\n . We also evaluated the effectiveness of routine disinfection procedures in eliminating ARB from restroom floors. Our findings revealed that sewage, sludge, diapers, food wastes and restroom floors are frequently contaminated with highly and moderately resistant strains of\n E. coli, K. pneumoniae, P. aeruginosa<\/jats:italic>\n and MRSA. Notably, we identified two variants of the\n bla<\/jats:italic>\n \n OXA51-like<\/jats:italic>\n <\/jats:sub>\n gene (\n bla<\/jats:italic>\n \n OXA-66<\/jats:italic>\n <\/jats:sub>\n and\n bla<\/jats:italic>\n \n OXA-180<\/jats:italic>\n <\/jats:sub>\n ) in\n \n \n A. baumannii<\/jats:ext-link>\n <\/jats:named-content>\n <\/jats:italic>\n isolated from these environmental sources. Furthermore, we detected seven ESBL-\n \n \n K. pneumoniae<\/jats:ext-link>\n <\/jats:named-content>\n <\/jats:italic>\n , five ESBL-\n \n \n A. baumannii<\/jats:ext-link>\n <\/jats:named-content>\n <\/jats:italic>\n , two ESBL-\n \n \n E. coli<\/jats:ext-link>\n <\/jats:named-content>\n <\/jats:italic>\n and one ESBL-\n \n \n P. aeruginosa<\/jats:ext-link>\n <\/jats:named-content>\n <\/jats:italic>\n , all carrying one or more ARGs (\n bla<\/jats:italic>\n \n KPC<\/jats:italic>\n <\/jats:sub>\n ,\n bla<\/jats:italic>\n \n NDM-1<\/jats:italic>\n <\/jats:sub>\n ,\n bla<\/jats:italic>\n \n CMY-2<\/jats:italic>\n <\/jats:sub>\n ), in isolates recovered from sewage, sludge, restroom floors and plastics. It is of note that ARB persisted on restroom floors even after disinfection procedures. In conclusion, this study highlights that environmental wastes indiscriminately discarded in residential areas and shared surfaces among individuals are heavily colonized by ARB carrying ARGs of significant public health importance.\n
