Multidrug-resistant Acinetobacter baumannii is a World Health Organization priority pathogen associated with hospital associated outbreaks. Its occurrence in vegetables and fruits is limited, with only a few reports till now but raising concerns regarding unnoticed community and hospital transmission. Grapes and environmental samples were screened for A. baumannii and cultured on selective media, bacteria were identified using species-specific PCR, VITEK, and biochemical testing. CLSI 2024 guidelines were used for antimicrobial susceptibility. Bacteriophages were isolated from Ganga, sewage, soil by enrichment, purification and plaque assay was done. Stability was measured throughout pH 3-10 and -80 °C to 60 °C, and transmission electron microscopy was used to analyse the morphology. A. baumannii isolates from different sources as soil and grapes showed resistance to multiple antibiotics. Five bacteriophages were isolated, ΦABGR01 and ΦABGR03, showed strong in vitro lytic activity against A. baumannii. These phages were stable and active across a wide pH (3-10) and temperature (-80 °C to 60 °C). Transmission electron microscopy revealed a podovirus morphotype with an icosahedral capsid and a short, non-contractile tail. This is the first report of MDR A. baumannii isolated from retail grapes in India, indicating a potential foodborne reservoir for this critical pathogen. Strong in vitro stability and activity were shown by environmental lytic phages, highlighting their potential as alternative treatments. These results underline the necessity of more thorough food safety monitoring as well as upcoming research that includes both in vivo and genomic validation.
